210 Miss G. Ricardo on 



Another male from Yoouzalein Vallej, Burma, April 1891 

 (^Col. Bwghain). 



A species at once distinguished by the pale ashy-white 

 tomentum on the first three segments of the black abdomen. 

 Moustache pale yellow. Legs black. 



Length, type 22, second male 18 ram. 



Face protuberant as in all the species here mentioned, 

 covered with ashy-grey tomentum. Moustache composed of 

 yellowish-white long soft liairs. Antennce witli reddish 

 bristly hairs on the lower sides of the first two joints, the 

 third joint elongated, nearly as long as the first two together. 

 Bristles on ocelligerous tubercle and posterior part of head 

 stout, black. Collar brownish black, with black bristles in 

 the centre and white hairs at sides. Thorax brownish black, 

 with some grey tomentum ; two dark median stripes ara 

 visible ; pubescence on dorsum thick, black, short, but longer 

 posteriorly, the ashy-grey tomentose shoulders with short 

 black hairs ; the stout black bristles at sides and posteriorly 

 are numerous. Scutellum the same colour as the thorax, but 

 the pale ashy-white colour of abdomen is visible on the 

 anterior half of scutellum. Abdomen blackish, the pale 

 segments with white pubescence ; this pale colour is continu'^d 

 on the sides of the segments, reaching in a narrow line to 

 the centre of the fourth segment ; pubescence on the dark 

 parts black, white at the sides of abdomen. Genitalia rather 

 large, black and shining, with black pubescence. Legs 

 black, with white pubescence and yellow bristles. Wings 

 clear, veins not strikingly attenuated. 



Andrenosoma, Rondani. 



Subgenus Pogonosoma, Rondani. 



Founded by Rondani in 1856 for species with three sub- 

 marginal cells ; but, as v. d. Wulp and Hermann point out, this 

 is hardly a good enough character to divide it from Andreno- 

 soma^ Rondani, some specimens having been found with the 

 dividing vein which separates the first submarginal cell into 

 two absent in one wing and present in the other. Hermann 

 states if it is retained it should be looked upon as a subgenus 

 of Andrenosoma {Nusa). 



The subgenus seems widely distributed in the Oriental 

 Region (where there are eight species), the Palaearctic and 

 Nearctic Regions (both represented by four species each). 



Rondani made Laphria maroccanum, Fabr., the type of 

 the genus.
