narrower three-waved band on the fourth, the fifth to shortly beyond the mid- 

 dle, a narrow line round its sides and apex ; the ventral surface with the follow- 

 ing black markings: the first segment, except for a triangular mark on the sides 

 at the apex, an irregular narrow line, narrowed to a sharp point at the apex, on 

 the centre of the basal two-thirds of the second, lines on the following three, 

 roundly dilated at the sides, and the whole of the last. Legs colored like the 

 body, but paler, the four anterior behind to beyond the middle of the femora 

 and the hinder all round to near the apex of the femora. Wings hyaline, the 

 base suffused with fulvous, the apex with violaceous, the costa and stigma ful- 

 vous. % . Length 7 mm. to end of second segment. 



Head and thorax strongly, closely punctured, thickly covered with dark fu.';- 

 cous hair. Ciypeus clearly longer than wide, sparsely, strongly punctured ; its 

 apex with a shallow rounded incision. Base of thorax transverse, the sides not 

 transverse. Apex of metanotum irregularly transversely striated ; the sides at 

 the top project into a clearly separated (especially at the base) testaceous tooth ; 

 they are irregularly margined on upper half. First abdominal segment cup- 

 shaped, sparsely, but distinctly punctured ; the second is almost square, not much 

 narrowed at the base; the basal half finely, the apical coarsely putictured, its 

 apex only very slightly reflexed ; the other segments are strongly punctured, 

 especially at the apex. 



Three Rivers, California. 



This species has the abdominal markings pretty much as in A. 

 duranrjoensis, which may be known from it by the sides of the pro- 

 notum projecting, by the strongly reflexed apices of the second and 

 third abdominal segments, and by there being a broad lateral mark 

 on the sides of the second ventral, on which there is no central line.

 Black; the ciypeus, mandibles, except the teeth, a small mark over the an- 

 tennae, broad and rounded above, obliquely narrowed below, a short narrow line 

 on the outer orbits above, underside of antennal scape, a line, narrowed in the 

 centre, on the base of pronotum, tegulse, a small oval mark on the sides below 

 them, two marks on the apical half of the scutelhim, rounded at the base, trans- 

 verse at the apex, the apical half of postscutellum and the greatar part of the 

 abdomen, bright sulphur-yellow ; the following parts of the abdomen are black : 

 the basal slope, the black produced in the centre at the apex, into a point of equal 

 width and slightly broader than long, its apex transverse, not reaching to the 

 centre of the yellow apical part, the basal fourth of second segment, the band 

 widened laterally; attached to it is a slightly narrower band which does not 

 reach the sides, the short pedicle by which it is attached to the basal band, being 

 as wide as its lateral projections, there are waved basal bands on the third to 

 fifth, and the apical is entirely black ; the first ventral segment is black, except 

 for a transverse yellow line near the apex ; there is a narrow tripartate line — the 

 central projection much smaller and more sharply pointed than the lateral — on 

 the base of the second ; from its sides projects a stout oblique mark, rounded and 

 slightly narrowed at the apex ; the following segments two are black at the base, 

 the last is entirely black. Legs of a paler yellow than the body; the greater
