This species differs from true Calliopsis somewhat as Macrotera 

 differs from Perdita s. str., and should perhaps fall with ahdominalis 

 into a distinct genus. At one time I thought it might be a Scrapter, 

 but that was surely an error. 



Andrena cerasipolii, n. sp. 



$ . Length, 10 mm. or a little over, head black, thorax and abdomen Prussian- 

 blue, tegulag shining piceous, legs black, antennae wholly black ; wings hyaline, 

 minutely hairy, apex slightly clouded, nervures and stigma piceous, the latter dark 

 rufescent in middle. Pubescence of head and thorax tolerably long and dense, more 

 sparse on dorsum of mesothorax and vertex, pale grey, mostly black on hindmost 

 half of metathorax, or scutellum and dorsum of mesothorax ; entirely black also on 

 clypeus, sides of face and about the antennae, black hairs also on the anterior part 

 of occiput. The pubescence of the cheeks, and of the middle of the face below the 

 antennfe, is dull white. Abdomen shining, pubescence white, sparse, mainly confined 

 to first segments, sides of the others, and venter. There is some short black pubes- 

 cence on the hindmost halves of the segments dorsally, only noticed when the insect 

 is viewed from the side. Pubescence of legG rather short, dirty wliite, and longest 

 on femora, more or less mixed with darker on tibise and tarsi. The hairs on hind 

 femora are clear shining white. Head broader than long, eyes small, distance be- 

 tween the ocelli less than the diameter of the middle one. Clypeus more or less 

 bluish. Face and front strongly and closely punctured, punctures of clypeus just as 

 close in middle as at the sides ; labrum shining, prominent, with a central pit, lower 

 margin of labrum fringed with reddish hairs. Second joint of flagellum barely 

 shorter than third. Mesothorax and scutellum with lai'ge, comparatively sparse, 

 punctures ; metathorax black, strongly rugulose or subcancellate, enclosed area not 

 bounded by a distinct rim, and sculptured much as the rest. Second sabmarginal 

 cell very short, higher than broad ; third narrowing more than half to marginal. 

 Abdomen strongly and closely punctured, the apical margins of the segments some- 

 what constricted. 



Kah. : Santa Fe, INT. M., on foliage of cherry in Mr. Boyle's 

 garden, morning of July lOth, 1895 (Ckll., 3432). Seven others 

 taken at the same time and place, flying round and settling on the 

 foliage of a peach tree ; all were males. In one the wings are sligbtly 

 dusky throughout. One specimen of this species was taken on July 

 Sth, 189i, at Sta. Fe (Boyle). 



This differs at once from A. ccerulea, Sm., by the colour of the 

 pubescence on the face, the punctured abdomen, &c. Using the table 

 given by Schmiedeknecht for the European species, it comes in the 

 neighbourhood of A. pilipes, Fl. 



nJ Perdita ignota, w, sp. 

 $ . Length, about 5 mm., head and thorax dark blue-green, tolerably hairy, 

 supraclypeal area brassy. Head of ordinary size, face and front shining, front with 

 Tcry sparse punctures ; clypeus, except the usual dots, and nearly circular lateral
