. Bulletin. Natural history; Natural history. 260 History Survhv I ol. 22, Art. 2 Since oiiitiftitalis was described, three additional specific names of closely related tornis have been proposed. V\g. 22 shows the modified anal cercus of a male speci- men from "Prairie Hills, B. C. July 1^. 1*>()S," in the collection of the American Kntomolo^ical Society of Philadelphia, which ajirees very well with pumllaiKt Nea\e (1'534) described from British Columbia. Fig. 23 shows the modified anal cercus as it exists in specimens from Oretjon that 1 described (1937) under the name of forcipatn. Clanssen {VMlh) proposed the name of s(ira for a species of this genus from New \Ork which very closely resembles the western (iciidcntalis and the related inrcipatn and purct'llaiia. Fig. 2AA shows the character of the variation observed in the modified anal cercus from a Massa- chusetts specimen; fig. 2AB from an Indi- ana specimen; 24C-f from Tennessee specimens. I am strongly of the opinion that all of these eastern specimens are of the same species, and the dif+erences arc due merel\ to variations in local popula- tions. The dilierences between sara and orci- dentalis are certainly slight, and there is reason to suspect that collecting in north- ern states and southern Canada will show- that sara is specifically the same as occi- (Itntalis. I he same fate in synonymy ma>' be in store for the more divergent forms described as forcipatn and purctllana. Un- til further evidence to this cfiect is pro- duced, hcwever, it seems the safest pro- cedure to hold occidentalis, forcipatn, purcellana and sara as distinct species, recognizing that certain specimens are merely variants (no names necessary) of these more widel_\ separated units. The recognition, for the time being at least, of tliese four major tvpes as species causes me to propose another specific name for an even more divergent form. Certainly, this new form deserves specific status
