l)o(l\- hairs; anierior, median, dorsal surface of prcnhorax hears a pair of j)romineiU 

 tuhercles, each tuhercle hearing two redcHsh-hrown, proniinenl, posteriorly 

 directed, curved spines (giving an antler-hke effect); posterior, median, dorsal 

 surface of prothorax hears a pair of smaller tuhercles each with two posteriorly 

 directed spines, the anterior spines heing strongly curved; mcsothorax bears a 

 pair of median tubercles each with a large, posteriorly directed spine and a 

 smaller, perpendicular one anterior to it; metathorax bears pair of tubercles 

 each with a posteriorly directed spine; bases of thoracic tubercles all bear smal- 

 ler, reddish- brown tubercles, those on mcso- and metathorax being arranged 

 in a circle; median, dorsal portions of abdominal segments one to eight bear 

 eight, large spines with tuberculate bases, arranged in a double row of four each, 

 the anterior four usually being anteriorly directed and the posterior four being 

 posteriorly directed; on last three abdominal segments these spines become 

 closer together and appear to radiate somewhat; last abdominal segment bears 

 a dorsal pair of prominent, anteriorly directed, curved, chitinous spines; all 

 spines reddish brown; fewer tuberculate, spine-like hairs on ventral surface. 



Adult. — Ischyrus quadripunciatns. This was described by Olivier in 1808 

 (Enc. Meth. Ins. \T, 437). Blatchley^ states that it is frequent throughout 

 Indiana, Jan. 21-Dec. 8, being gregarious in winter and hibernating beneath 

 bark and logs, also it is often found at sap in early spring and on fungi in the 

 summer. Smith^ records it only from Caldwell and Westville in New Jersey, 

 but it occurs in various other places in the state. Chagnon* lists it from Quebec, 

 Canada. Beutenmuller in his ''Bibliographical Catalogue of the Described 

 Transformations of North American Coleoptera"^ gives the following single 

 reference to the larva, "1855, Larva (Fig.) Chapuis et Candeze. Mem. Soc. 

 Sc. Liege Vn I, 22 pi. 



NOTE ON THE DISTRIBUTION OF ATTEVA AUREA FITCH. 



BV frank M. GIBSON, PH. D., 

 Baltimore. Md. 



This moth was first described by Asa Fitch in his Third Report on the 

 noxious, beneficial and other insects of the State of New York, but he does not 

 report its occurrence in that State, having prepared his description from a 

 specimen sent him from Savannah, Georgia. Dyar gives its habitat as the 

 Southern States; Holland as the southern portion of the region covered by his 

 Moth Book, from the Gulf States southward and westward, into Mexico and 

 lands still further south. 



. In July of the present year, I found in this city, feeding upon ailanthus, 

 certain larva? which were unknown to me. They pupated while suspended in a 

 loose, irregular net spun among the leaves, and emerged July 25-28. I sent 

 one of these to Dr. Barnes, who kindly confirmed my identification of it, and 

 stated that he had raised the moth at Decatur, Illinois, on ailanthus, and that 

 Mr. Poling had bred it at Quincy in the same State. This would indicate a 

 far wider distribution for it than that assigned by Holland and Dyar.
