This has nearly the colours of" A. pcrimelus, Ckll., but it is 

 smaller, and the hair of the head is quite diH'erently 

 coloured ; it is soniethinj? like ^1. perple.va, but the hair 

 of li'^s is quite a (iHTeicnt colour, &c. ; it ditlVrs at once 

 from viilna in the eoKnir of the thoracic hair, and from 

 Carliui it is easily separated by tiie area of nictathorax more 

 coarsely fjranular, and broader above, colour of hair at sides 

 of nietathor;ix, ii:c. The colour of the thoracic hair recalls 

 A. H/il'i, but it is not that species.

Andrenu pyrura, s[i. n. 



? . — Length about 11 ram. 



Black ; hair of head and thorax long, greyish uhite, with 

 a slight creamy tinge on scutcUum, &c. ; that on legs mostly 

 yellower, on inner side of basal joints of tarsi light golden 

 fulvous ; abdomen withoxit hair-bands, but with some line 

 white hair, which in certain lights shows up as ])atchcs at 

 the sides of the segments (very much as in A. Wilmattce); 

 caudal fimbria very bright golden red ; tegulae piceous with 

 a reddish spot. AVings yellowish, with the apical margin 

 broadly smoky ; stigma aiul ncrvures ferruginous, the stigma 

 fairly large ; first i-. n. joining second s.m. about the middle; 

 second s.m. obli([ue. Process of labrura very broad, sub- 

 truncate; clypens strongly and densely punctured, with au 

 ill-defined median line; antcnnie dark, third joint con- 

 spicuously longer than 4 + 5; mcsotliorax dull, rather 

 obscurely punctate ; area of metathorax triangidar, not 

 bounded by a rim, dull and granular, with weak plications; 

 akdomen rather shining, with small but \ery di>tinct 

 punctures ; basal joints of tarsi large and fiattencd ; spnrs 

 light brownish. Facial fovtic, seen from above, very pale 

 greyish, or greyish white, vciy broad, occupying al)out three 

 quiiiters ol the distance between eye and antenna, separated 

 Irom eye only by a narrow line, ending at the level of the top 

 of the clyi)eus, 



Aery much like A. salicijloris, Ckll., but the second 

 abdominal segment is depressed much less than half, and 

 that feebly, whereas in salicijloris it is depressed two 

 thirds; the area of metathorax wholly lacks the transvcise 

 ridge posteriorly, seen in sulu ijloris ; the wings are much 

 yellower, und the sculi)ture ot the unsothorax is entiiely 

 different. In Ixobcrtson's tables it runs as near to corni 

 (= covimoda) as anything. It is evidently near to commoda, 

 but differs by the clypeus lacking a distinct median ridge,
