bined ; of the first four joints each is a little longer than the one 

 beyond ; fifth equaling second, third, and fourth combined. 



Color : Antennae with stalk brown, and pectinations light yel- 

 lowish-brown, tipped with darker; elytra, anterior and median 

 legs about color of the pectinations of the antennae ; posterior 

 legs somewhat darker ; head and thorax black ; abdomen dark 

 brownish ; elytra hyaline, clouded at middle with brown. 



Myodites fasciatus Say, brunneus n. var. 1 



Say's description is so general that the author has not dared 

 to call this a typical fasciatus. Before deciding that this is Say's 

 species, it would be necessary to see the type or topotype. The 

 first joint of the hind tarsi is as long as the succeeding three 

 joints, about once and a half as thick, and slightly emarginate 

 and obliquely truncate at tip. The abdomen has a distinct brown- 

 ish luster. The antennae are brown with black at base ; elytra 

 reddish yellow ; wings clouded with fuscous ; legs light brown, 

 tarsi yellow ; prothorax with abbreviated median line ; 6 mm. ; 

 West Point, Neb., June 20. Specimen in collection of the Uni- 

 versity of Nebraska. 



A specimen at Manhattan, Kan., answers this description also: 

 5.5' mm. ; Riley county, Kan. ; Popenoe, May. 



Melander and Brues in their paper on the genus Halictus 

 record this species as follows : 



"Inasmuch as Fabre and others have found the larvae and 

 pupae of a member of this family in the cells of a European 

 species of Halictus, it is quite interesting to note the occurrence 

 of M. fasciatus about the colonies of the American form. Sev- 

 eral specimens were taken while sweeping with the net among 

 the swarming bees as they entered and left their nests." 



The following table will aid in the determination of the species 

 of this genus, found in the United States. It is largely remodeled 

 from Le Conte, Trans. Am. Ent. Soc, 1880, vol. VIII, p. 210:
