[125.] In Europe there are found, in ant-hills, little jumping insects 

 about three twentieths of an inch in length, of a brownish color, with an 

 egg-shaped body, entirely destitute of wings and wing-covers. The head is 

 very small, and nearly concealed under the forepart of the body; the bind- 

 most thighs are remarkably thick; and the female has a very short piercer, 

 not exceeding the terminal appendages in length. These insects belong to 

 the genus Myrmecopliila. Several years ago I observed that cucumber vines 

 were much infested by some minute jumping insects, rather less than one 

 tenth of an inch long, of a broad oval shape, and black color, without wing- 

 covers or wings, but furnished with short thick hinder thighs. They in- 

 jured the vines very much by eating holes into or puncturing the leaves, 

 and were expelled by dusting the plants with flour of sulphur. These 

 cucumber-skippers were so soft and tender, and withal so agile, that it was 

 difficult to catch without crushing them. Consequently I was unable to 

 examine them thoroughly, and failed to preserve specimens of them. It is 

 possible that they may come near to the genus Myrmecopldla, which was 

 unknown to me at the time; and since then these minute insects have 

 escaped my observation. They were very different from the little flea- 

 beetles (Haltica cucumeris or pubescens), also found on cucumber-vines, 

 which have already been noticed among the Coleopterous insects.

[264.] In the early part of August another kind of tussock-moth is some- 

 times seen on fences or on the sides of buildings. Both sexes are winged, 

 the females differing from the males only in being of a larger size, and in 

 having antenna? which are not distinctly feathered. They are of a brownish 

 gray color; their fore- wings are traversed by two zigzag brown lines, and 

 these are crossed by a straight brown line running parallel to the inner 

 margin, and there is a large pale spot near the middle of the front margin; 

 on the top of the abdomen are two little tufts composed of black glittering 

 scales. The wings expand from one inch and a half to two inches. These 

 moths belong to the genus Dasyclura, a word signifying thick hand, and 

 applied to insects of this kind on account of the thick covering of hairs on 

 their fore-legs. The present species seems to be the Icucopltaa, or brown 

 and white tussock-moth, figured in Mr. Abbot's sumptuous work on the 

 insects of Georgia. The caterpillar I have not seen; but in the figure of it, 

 given by Mr. Abbot, it is represented of a greenish yellow color, clothed 

 with yellow hairs on the sides, with four yellow brush-like tufts on the back, 

 and two brownish pencils on the first, eleventh, and twelfth rings. It is
