364 T. D. A. COCKERELL. 



sumably, judging from the other characters, the tongue is of the 

 Colletid type, although the insect has an extraordinary superficial 

 resemblance to the American Andrena prunorum Ckll. The hind 

 legs have a very distinct,' lanceolate, knee plate. The last antenna! 

 joint is flattened at apex. 



Andrenopsis flavorufus sp. n.— % Length about 10i mm.; head 

 broad, but facial quadrangle considerably longer than broad, the orbits slightly 

 converging below; face and vertex with much long orange hair, cheeks with 

 white hair; mandibles (except apex), labrum, clypeus and supraclypeal area yel- 

 low ; clypeus with the anterior margin rather bulging, smooth and very shiny, 

 the sides well punctured ; malar space obsolete ; antennae ordinary; scape yellow 

 sutfused with red ; flagellum clear ferruginous beneath and blackish above, not 

 mouiliform ; fourth antennal joint very short, broader than long; thorax black, 

 with the hair above fulvous, and beneath white; mesothorax exceedingly densely 

 punctured, with distinct median and parapsidal lines; scutellum rough with 

 punctures like the mesothorax; area of metathorax dull, roughly sculptured, 

 without any trace of a transverse keel ; its margin with little cross-ridges sepa- 

 rating shining pits; tegulse ordinary, shining, yellowish-ferruginous; wings 

 somewhat dusky, darker on apical margin; stigma and nervures dark brown; 

 second recurrent nervure bulging outwards; anterior cox* rather swollen, dark 

 brown ; femora and tibiae clear shining ferruginous, with pale, slightly yellow- 

 ish hair ; tarsi light yellow ; basal joint of hind tarsi flat and rather broad ; abdo- 

 men black, with the hind margins of the segments broadly ferruginous; the 

 second segment is all ferruginous except a patch in the middle and one at each 

 side, and the third is ferruginous at base; the surface is minutely granuloso- 

 punctate, and there is a good deal of erect, pale fulvous hair; the basal half of 

 the venter is pale yellowish-ferruginous and bare, the apical part hairy and 

 much darker. 



Hab. — " Australia " (no other particulars known); in the Brit- 

 ish Museum, from the F. Smith collection, 79.22. Compared with 

 Biareolina (neglecta Dours), our genus is easily recognized by the 

 venation. In Biareolina the marginal cell ends in a blunt point on 

 the costal margin, and the stigma is large ; in Andrenopsis the mar- 

 ginal cell is obliquely truncate, ending in a point away from the 

 costal margin, and the stigma is small. 



POSTSCRIPTS. 



(1) Vachal (Bull. Soc. Ent. France, 1905) has proposed the 

 genus Manuelia for Halictus gayi, posticus and gayatinus. 



(2) Alf ken has recently asserted that the Chinese Nomada versi- 

 color, Smith, is the same as N. japonica Smith. When I had the 

 types (both females) before me, it did not occur to me that they Were 

 identical, though they are certainly allied. I believe that they are 

 distinct species.
