Systropha planidens (Giraud). 

 Three specimens ; Quetta. 



Osmia sponsa, n. sp. 



9 Closely and finely punctured, median segment minutely rugose, 

 with no enclosed space ; mandibles with two longitudinal carinse, biden- 

 tate, the inner tooth broad, blunt, almost bifid; clypeus with its 

 anterior margin transverse ; 1st and 2nd joints of flagellum of antenna 

 subequal, 3rd and 4th also subequal, shorter than 1st and 2nd ; scutellum 

 prominent, level with the mesonotum ; median segment short, round- 

 ed, almost vertical; abdomen nearly cylindrical, convex, shorter than 

 head and thorax united. Dark blue, abdomen brighter blue, shining ; 

 clypeus blueish black, antennae piceous, legs, including calcaria, black ; 

 pubescence greyish white, somewhat sparse, forming entire narrow 

 subapical bands on abdominal segments 1 — 5 ; scopa white ; pubescence 

 on inside of posterior tarsi black ; wings hyaline, very slightly infuscated 

 at apex, nervures and tegulae piceous. 



$ Similar ; no pubescent bands on abdomen ; front with long greyish 

 pubescence ; wings clear hyaline, very slightly infuscated in radial cell. 



Long. 9 7-8 mm. $ 5*5 mm. 



Habitat — Quetta; not uncommon, but I only obtained one $, which 

 may be an unusually small specimen. 



Much smaller than 0. adce, which has no pubescent bands on the 

 abdomen. Nearer to the European 0. gallarum (Spin.), but clypens 

 not emarginate, abdominal fasciae 1 — 3 not interrupted, and wings only 

 slightly infuscated. 



Osmia balucha, n. sp. 



9 Head and thorax closely and finely, abdomen more minutely, but 

 very closely, punctured ; lower margin of eyes not reaching the base 

 of the mandibles, and the portion of the face between them enlarged and 

 subtuberculate on the outer side ; clypeus with a median longitudinal 

 carina, its anterior margin produced, sub-porrect, deeply triangularly 

 emarginate, leaving two triangular sub-porrect laminae ; remainder of 

 head, thorax and abdomen with the sculpturing to a considerable extent 

 hidden by the pubescence. Aeneous green, the head and thorax some- 

 what darker than the abdomen; all the calcaria, and sometimes the 

 apical two or three joints of the tarsi, rufo-testaceous ; pubescence grey, 

 mixed with a few black hairs ; abdomen with ciliated bands of fulvescent
