 parallel-sided, not quite twice as long as wide. Wings long, (anterior 

 wing 45 mm.) tinged with yellow, nervures and stigma ochreous.

^, l - 3-l # 8 mm. Head and thorax reddish ochreous, the head some- 

 times darker or brownish, abdomen brown. Legs, antennae and 

 mandibles pale ochreous, the flagellum slightly infuscate. Differing 

 from the type species by the colour and shorter scapes, the latter 

 only just reaching the hind margin of the head. It is closely allied 

 to var. mediorufa Forel, from which it differs by its larger size and 

 by the shallowly concave hind margin of the head, (convex in mediorufa).

§. 1*3-1 *5 mm. Colour as in the type, excepting the flagellum 

 which is dark brown, the first two joints excluded. It differs from 

 the type of the species as follows. The metanotum is much longer, 

 almost as long as the mesonotum; the meso-epinotal suture is 

 very shallow. The pair of stigmata on the epinotum are less pro- 

 minent and the dorsum of the epinotum is more convex lengthwise. 

 Otherwise like the type of the species. 



9- 3*1 mm. (hitherto undescribed). Smaller than the type of the 

 species and of a more reddish brown colour. The wings are fuscous, 

 not tinged with ochreous as in the type, nervures pale brown. The 

 scapes reach just beyond the hind margin of the head, and the latter 

 is not wider than long. The mesonotum is narrower than in the 

 type species, or as long as wide, and the scutellum is barely more 

 than one-third the length of the mesonotum. 



cf. 1*5-2 mm. Pale brown, the head somewhat darker, tarsi and 

 antennae more or less yellowish. Slightly shining, smooth, feebly 

 pubescent. Pilosity wanting. Head subquadrate, clearly wider than 

 long, the posterior half a trifle narrower than the anterior half. Eyes 

 large, occupying the anterior half of the sides of the head; the dis- 

 tance between the posterior ocelli is twice as great as between them 

 and the anterior ocellus. The scape extends a little beyond the 

 posterior margin of the head ; 1st joint of the flagellum as long, or 

 nearly as long as^ the 3 following joints taken together. The scutellum
