ments 2 to 4, and more or less of a basal band on 2 ; hind margin of first 

 segment narrowly dull white; fifth and following segments with black 

 hair, .but the hair on the apex of fifth is partly light, producing a rather 

 ill-defined light band ; spines at sides of fifth a'nd sixth segments well de 

 veloped ; apical plate dark red, with the apical part black, squarely and 

 deeply notched at sides; hair of venter entirely reddish-fuscous, not very 

 dark. In my tables it runs to M. communis Cress., but it is easily separated 

 by its larger size, red tegulse, much less black hair on thorax, and very 

 yellow wings. I at first thought it might be a form of M. illinoensis Rob. 

 (which I know only from description^, but it is larger, the venation appears 

 to be different, and the wings are strongly yellow ; the ornamentation of 

 the abdomen also appears to be different. It must also resemble M. comp- 

 toides Rob., but the dark hair on scutellum, the light hair on fifth abdom 

 inal segment, and other characters are sufficient for separation. In its 

 build, and the banding of tr/e' abdomen, it is very much like M. blakei Ckll., 

 9 , but close comparison shows that it can not well be the male of that 

 species.

M. hortivagans var. a. 



A series of five males and one female from Morton Co., Kansas, 3,200 

 feet (F. H. Snow 1787, 435, 433, 432, 431, 1788) must be referred to M. hor 

 tivagans as a variety. The males agree with hortivagans, except that they 

 have the stature of communis. The female resembles communis (taking the 

 Georgia examples as typical), but differs by being more robust, with a 

 much broader abdomen ; the legs with less light hair ; and more space 

 between the sides of the black patch on the mesothorax and the tegulae, 

 owing to the fact that the thorax is broader than in communis, while the 

 black patch remains the same size. The tegulae are dark with a narrow 

 reddish margin. Both sexes were taken in June. 



Melissodes galvestonensis sp. nov. 



Female. Length about 11 mm.; hair of face and cheeks white, of occi 

 put faintly yellowish ; vertex with black hairs, not very numerous; flagel- 

 lum, after second joint, rather dark ferruginous beneath ; mandibles with 

 a broad rufo-fulvous apical stripe ; thorax above with dense, short deep, 

 rufo-fulvous hair, a patch on hind middle of mesothorax, and anterior part 

 of scutellum, exposed, shining but strongly punctured ; hair of lower part 

 of pleura black in front, white behind, that of the rest of pleura grayish or 

 dull ; tegulse rufous, dark in front ; wings dusky, nervures dark fuscous ; 

 hair of legs pale but dull ; a sooty patch on outer side of middle tibiae ; hair 

 on inner side of basal joint of hind tarsi, and their tibiae except at extreme 

 base, bright ferruginous, scopaon outside of these joints white or yellowish- 

 white, in the type filled with bright orange pollen ; abdomen with an en 

 tire but narrow median band on second segment, and basal bands on 2 

 and 3, of yellowish tomentum ; 4 covered with white tomentum, except a
