Also specimens which I identify doubtfully as the following : — 

 A. nigriceps (Kirby) ; Baluchistan. 

 A. minutula (Kirby) ; Baluchistan. 



(a) Abdomen more or less red. 



Adrena unita, n. sp. 



9 The pubescence, though somewhat sparse, hides the sculpturing 

 of the head and thorax ; median segment very finely rugose, with no 

 enclosed space ; abdomen minutely aciculate ; lamina at base of labrum 

 short, transverse at apes ; second joint of antennse longer than the two 

 following united, vertex much narrowed and very convex ; median seg- 

 ment short, narrowed and rounded posteriorly ; abdomen as long as 

 head and thorax united, narrowed at base and apex. Head and thorax 

 black, apical two-thirds of flagellum red below ; legs black, the apical 

 3 or 4 joints of all the tarsi rufo-testaceous, calcaria pale testaceous ; 

 abdomen pale red, shining, two very small lateral dark spots on 2nd 

 segment, the first three segments almost entirely without pubescence ; 

 pubescence, including scopa and anal fimbria, greyish white, the anal 

 fimbria with a slightly pale fulvous tinge above ; wings clear hyaline,

 Black; the 1st, 2nd, 3rd, and sometimes the lateral margins of the 4th 

 abdominal segments, the anterior tibire below and at apex, the posterior
