EPUJALXES. 185 



infuscate ; areolet triangular and laterally coalesceiit above, 

 emitting the recurrent nervure from its basal fourth. 



Length 19 millim. 



ASSAM : Khasi Hills (llothney}. 



Type in the British Museum ; the apical half of the abdomen 

 is wanting.

Ephialteslonyirentris, Cameron, Zeits. Ilym.-Dipt. 1908, p. 37 ( $ ). 



$ . A black species, densely clothed with white pubescence, 

 which is longest on the sides of the thorax and abdomen. Head 

 immaculate ; face finely punctate and centrally subglabrous, as 

 are also the frons and vertex. Antennas black, with the scape, 

 except above, bright citrinous. Thorax immaculate ; the pro- and 

 meso-pleune glabrous and nitidulous, mesonotum closely but not 

 strongly punctate ; metanotura much more strongly and apically 

 closely punctate, extending to the lateral carinae ; metapleur* 

 glabrous and nitidulous. Abdomen elongate and slender, with the 

 two basal segments longer than the head and thorax ; first seg- 

 ment only slightly longer than half the second ; terebra only 

 slightly shorter than the body. Legs with the anterior pairs 

 bright flavous ; hind ones with their coxae and femora bright 

 red, their trochanters basally black and apically white, their tibia* 

 and tarsi dull pale flavescent, with the former below and at their 

 apices entirely black ; apices of all the tarsal joints subinfuscate. 

 Wings hyaline, with the nervures and stigma black. 



Length 27 millim. 



SIKKIM (Col. C. I. Bingham). 



Type. Location unknown. 



I have not seen this species, of which Cameron (/. c.) says : 

 ' The abdomen is longer and thinner than usual ; as compared 

 with E. iridipennis, Cam., from Simla, apart from the marked 

 difference in the colouration of the legs, that species may be 

 known by the first abdominal segment being longer than the 

 second. In E. latiannulata, Cam., from Sikkim, the first abdominal 

 segment is as long as the second, the abdomen is stout, not elon- 

 gated, and the legs are rufous, the four hinder tarsi black, the 

 hind tibiae black, broadly white above." It may be the $ of 

 E. tinctipennis, though femoral coloration is usually constant in 

 this genus. 



127. Ephialtes latiannulatus, Cam. 



Ephialtes latiannulatus, Cameron, Tijds. Ent. 1907, p. 90 ($). 



5 . A black species, with only the pronotum pale, and the terebra 

 longer than the body. Head with the frons and vertex smooth 

 arid shining, but laterally closely punctate ; face, except laterally, 

 with deuse elongate and infuscate pubescence ; palpi pale flavous.
