mostly pale, but black or dark fuscous on inner side of 

 middle and bind tarsi, shining fulvous on inner side of 

 anterior tarsi ; scopa of bind legs abundant, in the type 

 full of orange pollen. Abdomen shining, but not ex- 

 cessively so, with narrow median white hair-bunds on 

 segments 2 to 4, and indications of a second (basal) band 

 on 2; the two apical segments with dark fuscous hair; hair 

 of venter dark reddish fuscous. By the colour of the hair 

 on the legs and thorax &c, this resembles M. Mizerc, but it 

 is evidently a distinct species. In addition to the characters 

 cited, the third antennal joint is shorter than that of Mizece. 

 Compared with M. pa/lidicincta, the abdominal bands of 

 blakei are narrower, the vertex is not so broad, and the black 

 hair on the scutellum is lacking. The insect is considerably 

 larger than M. grindeUce, and otherwise different. 



Hah. l^eulah, New Mexico, end of August {Cockerell). 



The name commemoratestheBlakerancli,the entomological 

 headquarters at Beulah during several seasons. The width 

 of the abdomen of blakei is 5 mm., of Mizece nearly 6. The 

 locality of M. Mizea is in the Upper Austral zone, that of 

 M. blakei in the Canadian zone. 



Melissodes chrysothamni, sp. n. 



? . — Length almost 18 mm. 



Large and robust, black, with pale ochreous pubescence, 

 tinged with fulvous on scutellum and anterior part of meso- 

 thorax ; without black on thoracic dorsum or vertex, or with 

 a few black hairs at each extreme side of vertex, above top 

 of eye ; hair of labrum, lower part of pleura, base of legs, and 

 ventral surface of thorax generally, black or sooty, perhaps 

 best described as brown-black ; hair of venter of abdomen, 

 of middle tarsi and inner side of bind ones black ; hair of legs 

 generally dark, but the middle femora, anterior femora 

 behind, and basal half of anterior tibiae on outer side have 

 light hair in considerable quantity; the anterior tibire have 

 dark red hair on inner side ; the copious scopa of the hind 

 legs (in the specimens seen filled with orange pollen) is light. 

 Abdomen dullish, broadened towards the apex; apical margin 

 of first segment rather broadly reddened in one specimen, 

 but not in the other ; first two segments not obviously 

 bandtd ; third and fourth with dull yellowish-white hair- 

 bands, that on third inclined to be interrupted, that on fourth 

 very broad and entire ; bases of third and fourth segments 

 with black hairs ; the two apical segments with black hair. 

 Eyes silver-grey ; facial quadrangle broader than long, l)ut
