slightly fuliginous, least so basally, %vith a slight violet reflection. 

 Tegulffi dark brown. Anterior coxjb pubescent in front; fore meta- 

 tarsi with nine comb teeth hardly longer than half the metatarsus. 

 All the tibiae and tarsi very dark brown. One female, 20 mm. 

 Otherwise as described in my paper ^ 



CHLORION RESINIPES Fernald. 



This has heretofore been known only from the female. A male now 

 in the collection of the United States National Museum, which I 

 have examined, has made possible the preparation of the following 

 description: 



The male of tliis species differs from the description of the female 

 published in 1906^ as follows: 



Clypeus quite long and convex, its anterior margin slightly exca- 

 vated in the middle, but with a rounded projection at the central third 

 of the excavation. The surface of this plate entirely covered mth 

 pubescence, but without any backward extension of the ferruginous 

 color from the middle of the anterior margin. Outer ends of the 

 longer clypeal hairs not tipped with black. Distance between the 

 lateral ocelli equal to or slightly greater than from them to the eyes. 

 Cheek less than half the wddth of the eye at its widest point. Scape of 

 antenna faintly ferruginous beneath. Lateral mesonotal pubescent 

 bands not meeting behind. Pubescence absent on the posterior end 

 of the median segment and along the stigmatal groove. There is no 

 sericeous band between the middle and hind coxae (nor on a female in 

 tliis lot). Petiole slightly bent, the projection of the curve being 

 downward, and on its posterior third ; as long as the second segment 

 of the posterior tarsus. Abdomen dull ferruginous, darker behind; 

 with a black spot on the first dorsal plate on each side rather toward 

 its posterior margin, and with a median triangular spot, apex forward, 

 at the anterior margin of the second plate (these markings are proba- 

 bly variable). Entire dorsal surface of the abdomen yellowish seri- 

 ceous and with coarse yellowish hairs on the last two plates. Ter- 

 minal plate broadly rounded in the middle and with a slight median 

 longitudinal ridge. Beneath, plates three to seven are coarsely yel- 

 low sericeous, the hinder margins of the fourth to seventh plates 

 emarginate, the emargination increasing posteriorly, and with the 

 hairs longer and coarser toward the sides, almost forming lateral tufts 

 on the sixth and seventh plates. Terminal plate truncate, rather 

 sharply acuminate from the center of the truncation. Wings with no 

 yellow tinge, evenly, slightly fuliginous and with a decided violet 

 reflection. Tegulse dark, almost black, but with traces of ferruginous
