I dedicate this genus to Lieut. H. O. Boger, K.N., to whom 

 the British Museum is indebted for the specimens of the 

 typical species described below. 



Boqeria princeps, sp. n. 

 (Pi. XIII. figs. 5-5 b.) 



cT- Length 20^-21| millim. ; width of front at vertex 

 2A-3 millim. ; widtli of head 8|- millim. ; length of wing 

 16 millim. 



General colour of thora.v brownish gret/, abdomen silvery 

 grey ; ground-colour reddish broion^ concealed by greyish dust ; 

 thorax and abdomen nearly bare above ; pleurce clothed with 

 thick white pile, which extends in a stripe above the base of the 

 wing to the base of the scutelluvi. 



Head almost precisely the same width as the thorax, the 

 latter appearing slightly broader at the base of the wings, 

 owing to the |)ilosity of the pleurai ; front thinly clothed below 

 with short appressed yellowish-white hairs, and above and on 

 the vertex with short erect blackish hairs, and forming a 

 rounded projection in front of the eyes when the insect is 

 viewed from above ; a narrow median shining black triangle 

 extending forwards from the anterior ocellus to a distance of 

 H millim. ; a strongly marked ridge surrounding the anten- 

 nary pit, except below, and bounded by the vertical semi- 

 circular fissura frontalis j antennary pit contracted below into 

 a narrow flattened median ridge extending to the oral cleft ; 

 septum separating the antennas well marked : anfetina; blackisii 

 brown, second joint reddish brown ; arista bright reddish 

 brown; first joint and extreme base of the second black; a 

 shining dark brown semilunar spot above the base of each 

 antenna, while, on a slightly lower level, a transversely elon- 

 gated shining spot of a similar colour extends upwards and 

 inwards from the margin of each eye; above each of the 

 latter spots a small silvery-white triangle, resting on the 

 margin of the eye : face and cheeks silvery white ; face covered
