essentially as in Robertson's Andrenoidea in the structure of 

 the anterior femora and in the Andrcna habitus. 



Coquillettapis melittoides, new species. 



Female 12 mm. long. 



Head with the occipito-clypeal distance greater than the ocular 

 distance, first joint of flagel on its upper side seemingly slightly longer 

 than the next two joints combined on their upper sides. The second 

 and following joints of the flagel excepting the apical joint subequal 

 and wider than long, tne apical joint approximately one and one-half 

 times as long as wide at base, ocelli forming a slightly arcuate row, 

 the posterior ones about as far from each other as from the nearest 

 eye margin, cheeks rounded off and at their widest part slightly wider 

 than the eye as seen from the side, malar space practically wanting, 

 mandibles siiple, except for a slight indication of a tooth on the inner 

 margin near the apex, tegument of the head mostly smooth, polished 

 and impunctate, a few scattered punctures on the cheeks and along the 

 eye margins on the front ; clypeus and labrum appear to be uniformly 

 uneven and shiny ; thorax above shining, and sparsely punctured, anter- 

 ior femora at base beneath produced into a hairy falcate process which 

 is directed downward backward and inward ; this process from base to 

 apex is approximately half as long as the femur, scopa of posterior 

 tibiae and metatarsi plumose on account of hairs that are branched and 

 most of which are longer than the greatest width of the joint to which 

 they are attached ; abdomen shining above and beneath, indistinctly 

 sculptured, being sparsely punctured and somewhat roughened above, 

 more closely punctured beneath. 



Tegument almost entirely black except where relieved by some brown- 

 ish, as in the mouth parts, tegulae and tarsi ; pubescence black except on 

 vertex, dorsum of thorax and first dorsal abdominal segment, where it 

 is ocherous.

PANURGOMIA, new genus. 



On account of its two submarginal cells, etc., this might be 

 relegated to a relationship with Rhophitbides Schenck. It is 

 however more likely, judging from its habitus, that this genus 

 is nearer Noinia and really an Andrenid with only two sub- 

 marginal cells, the first nearly one and a half times as long as 

 tbe second on the cubital vein. In the relationship between 

 the posterior angle of the mandible to the posterior eye margin
