318 MICHIGAN SURVEY, 1908. 



Eocky Mts. areas in New Mexico and westward to the Pacific. (Titus 

 1906, p. 158, Cockerell 1906) (1 and 2). Notliing is known of its 

 breeding habits. I have specimens from eastern Canada and New Eng- 

 land but have seen none from south of New York along the Atlantic 

 region. There are mites on the Isle Koj^ale specimens. 



Xanthosarus melanophcea Smith. (Det. Titus). Taken on jack pine 

 ridge (108) ; about camp at Rock llarbor (133, 166 eleven) and on flow- 

 ers of Campanula rotnndifoUa in clearing at Siskowit Bay (148, 202). 



Geographic range: Described from British America, Smith 1853, p. 

 91 and known to occur throughout the region of southern Canada, New 

 England, New York, and in northern United States to the Pacific coast 

 and in British Columbia. This and the following species are leaf-cut- 

 ters working especially on the leaves of Rosa spp., the pieces clipped 

 out are used in lining their nests which are usually made in old logs 

 or dead trees, the female often utilizing the abandoned boring of some 

 other insect. The little rolls are often found when splitting logs or 

 Avood in the fall or winter. 



Xanthosarus latimanus Say. (Det. Titus). Very frequently taken 

 about the camp clearings at Rock Harbor and Siskowit Bay (38, 49, 68, 

 133, 137, 153, 179, 231)"; also at sand beaches at head of Conglomerate 

 bay (31) ; on jack pine ridges (68, 1-8 1 ; near Neutson's resort (121) ; on 

 flowers of Opulastcr (148) ; and on flowers of Campanula rotnndifoUa 

 (202). 



Geographic range: Described from "Arkansas" by Say 1823, p. 81, 

 which may mean any where from Missouri to Colorado. It is one of the 

 most common species in the United States and Canada, occurring from 

 coast to coast and from the Gulf northward. 



AntJvemois sp. near infragilis Cresson (Det. Titus). This specimen 

 was taken around camp at Rock Harbor (86) . "VSTiile it bears a close 

 resemblance to A. infragilis there are sufficient differences to make it 

 a good species and probably new. A. infragilis was described from 

 New York and probably occurs in the Isle Royale region, since I have 

 seen specimens from Canada (Titus 1906, p. 152). 



Stelidae. 



Cwlio.rijs moesta Cresson. (Det. Titus). One on flowers of Cmn- 

 panula rotundlfolht in clearing at Siskowit Bay (202) (V, 2).

 403; reported by Provancher, 1882, p. 241, 1883, p. 725 as tristis, from 

 Canada. Occurs Avestward to Colorado, New Mexico and probably 

 Utah.

 Rock Harbor (26). 



Geographic Range : Desc. from New Y'ork by Cresson, 1878, as 

 a Stclis and from Canada by Provancher, 18SS, p. 322 as Clielrm 

 lahiata and in Panurgidae. Ashmead, 1896, p. 283, erected the genus 

 ,'\[elanostcUs for his species ietheli, which is congeneric with ivitida 

 (Titus, 1906, p. 161).
