The plant-lice "naturally" reproduce through the summer by unfertilised eggs producing only females, but in the first cold of autumn males are hatched from some of the eggs, and the eggs of this generation are fertilised and bide through the winter, hatching in the following spring.

Whatever the husbands were and Jasper had almost insinuated that the males occasionally allowed themselves some latitude they appeared to be as faithful to their husbands as the ancient Roman matrons were to theirs. Roman matrons! and, after all, might not these be in reality Roman matrons? They called themselves Romans; might not they be the descendants of the old Roman matrons?

This suspicion will appear somewhat less improbable after we have seen what strong antipathies and preferences female birds occasionally evince towards particular males. Before we further discuss the question whether the females select the more attractive males or accept the first whom they may encounter, it will be advisable briefly to consider the mental powers of birds.

It will also be admitted that species of the same group differ from each other more widely in their secondary sexual characters, than in other parts of their organisation; compare, for instance, the amount of difference between the males of gallinaceous birds, in which secondary sexual characters are strongly displayed, with the amount of difference between the females.

Well, the captive insect fiercely attacks this lining, which to its eyes represents the pithy layer of its usual abode; it tears it away by tiny particles and strives to cut itself a road between the cocoon and the glass wall. The males, who are a little smaller, have a better chance of success than the females.

With species in a state of nature, every naturalist has in fact brought descent into his classification; for he includes in his lowest grade, that of species, the two sexes; and how enormously these sometimes differ in the most important characters is known to every naturalist: scarcely a single fact can be predicated in common of the adult males and hermaphrodites of certain cirripedes, and yet no one dreams of separating them.

People disguise themselves as giants and wild beasts, they also parade images of serpents, elephants, tigers, peacocks, &c. Dancing is carried on with enthusiasm by the males, the girls, clad in their best attire, remaining on-lookers. Before the meeting breaks up the males play a sort of game of hockey with wooden balls. Genna The word genna is one in common use amongst the Naga tribes.

Most males are perfect by the thirtieth day, but females seldom before the forty-second or forty-fifth day, because the heat of the womb is greater in producing the male than the female.

Claire's ambition had once been babies and a solid husband, but as various young males of the species appeared before her, sang their mating songs and preened their newly dry-cleaned plumage, she found that the trouble with solid young men was that they were solid. Though she liked to dance, the "dancing men" bored her.

The imprisoned female of certain nocturnal species, for instance, will attract the males from a comparatively immense distance, under conditions in which neither sight nor hearing could have been brought into play. The emission of odors and acute sensibility to them is the only presumable agency at work in those instances.
