206 THE ENTOMOLOGIST. 



rugose ; the clypeus produced, shining and truncate ante- 

 riorly, having only a few scattered punctures; the face, along 

 the inner margin of the eyes, with a line of short fuscous 

 pubescence ; from the anterior ocellus a shining carina runs 

 to the base of the clypeus. The thorax subopaque, with 

 scattered fuscous pubescence, that on the sides and beneath 

 griseous and very sparing; the floccus at the base of the pos- 

 terior femora white ; the posterior tibiae have the scopa fuscous 

 above and silvery white beneath ; the wings subhyaline, the 

 nervures fuscous. Abdomen oblong-ovate, widest towards 

 the apex and much narrowed towards the base, glossy black 

 and with very delicate punctures, the apical fimbria fusco- 

 ferruginous. 



The general aspect of this species is that of a species of 

 Halictus ; its produced nasus is a striking characteristic. 

 The species is remarkable in being apparently an enlarged 

 representative of the British Andrena Coitana. 



Nomncia mnculifrnns. — Female. Length 4 lines. Ferru- 

 ginous, wilh three longitudinal black lines on the thorax ; the 

 abdomen spotted with yellow. Head : the antenna3 fuscous 

 above ; a black macula extends from the insertion of the 

 antennae to the ocelli, which it encloses ; a smooth yellow 

 spot on each side of the clypeus of a somewhat triangular 

 shape ; the head otherwise, as well as the thorax, closely 

 and strongly punctured. The mesothorax with three lon- 

 gitudinal lines ; the metathorax and the base of the femora 

 black ; the metathorax ferruginous on each side ; the scutel- 

 lum ferruginous ; the sides of the metathorax with a little 

 cinereous pubescence ; the wings subhyaline, their margins 

 fuscous ; the tegulse ferruginous, the nervures fusco-ferru- 

 ginous. Abdomen ferruginous, with the base and the apical 

 margins of the three following segments black ; the second 

 segment has on each side a large subangular yellow spot, a 

 minute one at the sides of the following segment, an inter- 

 rupted transverse line at the base of the fourth, and a large 

 quadrate yellow spot on the fifth ; beneath ferruginous. 



This species closely resembles the darker examples of the 

 Nomada ruficornis of Europe, but the smooth yellow spot on 

 each side of the face is never found in any of the European 

 specimens.
