rather strongly developed horns. Later Mr. Davis collected one male 

 of the same form. Another lot of both sexes (two males, three 

 females) was received from Mr. Davis from the same locality, smaller 

 in size and with less developed prothoracic horns. I collected three 

 specimens on Staten Island with still less developed prothorax and a 

 similar lot in Queens, L. I., on swamp oak and walnut, all males. At 

 Lake Hopatcong, N. J., I found fourteen on a walnut having the 

 horns only slightly indicated. Both sexes were represented. One, 

 however, from the same tree had rather strongly developed horns. 

 Finally I got one female from Hempstead, L. L, collected by Mr. Ch. 

 Olsen, with highly developed, wide ear-like horns, showing how 

 extreme the variations may be. In size they vary from 6.5 to 9.5 mm. 



SMILIA CAMELUS FABRICIUS AND SOME OF ITS 

 VARIATIONS. 



By Ignaz Matausch, 



Newark, N. J. 



Through the kind assistance of some of my fellow entomologists 

 I have been able to make observations on the variations of Smilia 

 camelus females. The males seem to be more constant, but the 

 females vary somewhat in size, and to a remarkable extent in colora- 

 tion and markings. 



Without doubt, as Mr. Van Duzee says, guttata Fitch and viridis 

 Coding are only varieties of camelus, and I think only of the females. 

 The first insects I received from Mr. G. P. Engelhardt and M. W. 

 Beutenmiiller, and one from Florida, were typical camelus females. 

 Mr. F. E. Watson collected on June 25, 1907, in New Foundland, N. 

 Y., two females of guttata having the transverse band formed by a 

 row of more or less heavy markings but otherwise they are the same 

 in color and form as camelus. Professor Filippo Silvestri collected, 

 besides two males, one female intermediate in size between male and 

 female of the dark form of the male. At the meeting of the New 

 York Entomological Society on November 17, 1908, I exhibited them
