Trypetes prodiictus. sp. nov. Trypetes barbatus, Trans. Am. Ent. 

 Soc. 2g: 171, 1903, S • 



This does not belong to the female described under the name of T. 

 barbatus. It can be distinguished from the male of T. cariitatus by the 

 ventral segment i being produced to a point; shorter antennee, with joint 

 3 more than one-half as long as 4; flagellum darker; clypeus more strongly 

 bearded. 



Carlinville, Illinois; 10 $ specimens. 



Osinia collitisice, sp. nov. Osmia major., Ent. News, /j; 79, 1902, ^J. 



Evidently this insect, described from one specimen, is not the male 

 of O. major. It is likely to be mistaken for the male of O. atriventris. 

 It runs a little larger; ventral segment 2 more finely punctured, its 

 apical margin rather densely pubescent; hind metatarsi unarmed; length 

 8-10 mm. 



Carlinville, Illinois; 10 ^ specimens. 



. Aiidreiia salictaria, sp. nov. — $ . In size, structure, colour and 



habits this specimen closely resembles A. Illinociisis. It is a little more 



slender; scutel minutely roughened and opaque; scutel and disc of meso- 



notum usually more ])urplish; fasciae on segments 2-4 more whitish, 



July, 1905.
