size for the Cryptini and a quadrate or (to any extent, breadth, and 

 size) transverse areolet for the Mesox/r/m/V. Into these two, certainly 

 very loose, divisions I .find all the genera with which I am acquainted 

 fall sufficiently naturally with no overlapping except in the case of 

 the Indian genus Etha, under which name Cameron had congregated 

 examples of both wing-types. The "small, square" areolet of 

 Stenomeris shows it to unmistakably belong to the Mesostenlni.

AGLAOCRYPTUS GLABRATUS, sp. nov. 



9 only. A strongly nitidulous, testaceous species with only the 

 abdomen somewhat dull ; ocellar region to centre of occiput, mandi- 

 bular apices, flagellum and dot on scape, onychii, costa and stigma, 

 black ; remainder of head, and the flagellar band, white. Head broad 

 and glabrous with the face longitudinally silicate between epistoma 

 and orbits, clypeus apically depressed and truncate, labrum exserted, 

 Notauli profound and entire to disc of mesouotum ; metathorax 

 glabrous with both transcarinae strong and entire, its spiracles 

 exactly circular and apophyses wanting. Scutellum smooth, not 

 margined. Abdomen narrow and confidently punctate, with anus 

 smoother and basal segment glabrous ; terebra a little shorter than 

 abdomen. Legs and the hyaline wings normal, with penultimate 

 joint of hind tarsi deeply bilobed ; areolet small and pentagonal, 

 emitting recurrent nervure from its centre ; uervelet wanting ; upper 

 basal nervure and nervellus postfurcal, the latter centrally inter- 

 cepted. Length, 9 mm. There is nothing distinctive about this 

 species (which has the facies of a small Mama, Tosq. = Colganta, 

 Cam.) but its subglabrous body, circular spiracles and bisulcate 

 face. 



The type was taken at Durban in Natal during February, 1913, by 

 W. Haygarth.
