also be entitled to somewhat less than specific rank, since in this 

 genus, as in Statira, specific difference seems to be indicated by a 

 difference in relative length of antennal joints rather than sculpture. 



Comparison has also been made with the original descriptions of 

 Sav's (Tiica and Kirby's donacioidcs, and with specimens, kindly sent by 

 Mr. J. I. Beaulne, of Ottawa, of the latter. The Canadian specimens 

 agree in every respect with those from the Atlantic States (of which 

 the collection of Mr. Wm. T. Davis contains a long series) and with 

 Kirby's description, based upon specimens from Lake St. Clair (be- 

 tween Michigan and Ontario) and Massachusetts. They do not 

 however agree with Say's description of A. ccnca, either in color or 

 locality for he describes an insect that is " green, sometimes tinged 

 with brassy " of which a specimen was obtained on " Red River " in 

 the course of an expedition to the source of St. Peter's River. This 

 would now be in North Dakota or northern Minnesota. I have been 

 unable to obtain any specimens from Say's type locality ; if any can 

 later be examined, it is possible that they may not prove identical with 

 Kirby's species; a possibility that becomes even a probability in view 

 of the variations already made known and the discrepancies in the 

 descriptions. 



It seems also advisable to point out that the statement in Leconte 

 and Horn's Classification that all our species of Lagriidse belong to 

 the tribe Statirinae requires correction as mentioned by Champion 

 (Biol. Cent.-Am. Col., IV, 2, p. 4). Seidlitz (Ins. Deutschl., V, 2, 

 1898) groups the species into three tribes, viz.: Trachelostenin?e, 

 Lagriinae and Statirin?e. The first comprises only six South American 

 species, the second includes Arthromacra and other genera of 

 palsearctic origin, the third includes Statira and other genera of 

 tropical origin; and it is interesting to note that while Arthromacra 

 occurs only in our northern region, Statira is represented by two 

 species in the Antilles and in our southern states by thirteen species of 

 which two reach as far north as Pennsylvania and New York. Many 

 of the species of Statira have become known through Mr. Schaeffer's 

 work in Arizona and Brownsville, Texas. Both genera occur in the 

 vicinity of New York City, one coming down to us from the north, 

 the other up from the south. 



I have not found any American reference to the food habits of 

 any species of Lagriidas; the European Lagria hirta, the first species 

 of the family to be described, has been repeatedly redescribed in all
