inclusive. True legs six, articulated, brown ; prolegs wanting, or re- 

 placed by double rows of hooks in pairs beneath the sixth, seventh, 

 eighth and ninth rings, and two single rows under the last rings. Spir- 

 acles brown. A few very short hairs on each ring, arising singly from 

 little hard points or pit-like, warty substances. Length from one inch 

 to one inch and a fourth." 



This is followed with the statement that on "August 17th, one of 

 these formed its cocoon of fragments of squash-stalks tied together with 

 a few silken threads." It is preceded with the mention: " Found sum- 

 mer and winter near the roots of squash vines, and also 

 in the roots " — probably referring to the cocoons. The 

 larva is shown in P'ig. 4, and in Fig. 5, the cocoon con-

taining colored plates (published in 1862), may find there (pi. V, fig. 8) 

 a figure which will enable them readily to recognize the insect when it 

 is seen, during the month of July, flying over the plants, and alighting, 

 from time to time, to deposit an egg. To others it may be of service 

 to state, in addition to the above description of the moth, that the insect 

 belongs to the family of Jigeriadm, sometimes known as "clear-wings," 

 from the wings being without scales. In this species, however, only the 

 hind wings are transparent, the front ones being opaque, and covered 

 with scales, as in nearly all of the Lepidoptera. 



The Family of ^geriadae- 



The ^^geriadcB bear a marked resemblance to wasps and hornets, 

 with their orange markings, narrow and usually transparent wings, and 



their flight by day. Most of them have 

 at the end of the body a tuft or brush of 

 stiff hairs, which they can spread out, at 

 pleasure, like a fan. The currant-stem 

 borer {^I'Jgcria tipulifonnis) illustrated in 

 Fig. 6, and the peach-tree borer {^T^. exi- 

 iiom) are perhaps the best known species 

 of the group. Within a few years past

through the studies of Mr. Henry Edwards, of New York. The latest

 American Sphinges, published in 1834, named but twelve species.
