Mtiirclla gen. nov. 



\'ertex flat, elongate, a little (leclivou.s, and somewhat sloping 

 laterally, about twice and one half as long as wide at the trun- 

 cate base, lateral margins parallel for about three-fourths of their 

 length, then diverging outwardly to a little beyond the anterior 

 margin of the eyes, then converging strongly, forming a round- 

 edly acute angle. In profile the head is subconical. Ocelli 

 lateral, a trifle nearer to the eyes than to the top of the head, 

 visible dorsally. FrcJis elongate, about twice and a half as long 

 as wide at antenna! scrobes, a little wider just basal of this, nar- 

 rowing apically and basally, basally acutely triangular, apically 

 subtruncate. Tempora very short and narrow. Genae deeply 

 impressed roundly in the middle. Clypeus not produced beyond 

 the apical margin of the genae. about twice as long as wide, 

 strongly carinate on the basal half, a little wider than the lora 

 wliich do not touch the posterior margin of the genae. Labium 

 reaching to anterior margin of fore trochanters. Antennae in- 

 serted anterior to the middle of the eyes (viewed in profile), the 

 eyes extending posteriorly beyond the apical margin of the frons 

 (thus separating this genus from the others) and decumbent 

 nearly one-half, on the pronotum dorsally ; seta long, more than 

 half the length of the body. Pronotum transverse, lateral mar- 

 gins fairly long, somewhat feebly carinate : posterio,r margin ob- 

 tuse-angularlv emarginate. Scutellum wider than long. Teg- 

 niina with one subapical and 4 apical cells ; the subcostal cell ob- 

 hf|uely divided near the apex by a fork of the radia'. Wing with 

 a supernumerarv cell, which however does not nearly reach thr* 

 apical margin of the wing, the next of the apical cells being thus 

 short and broad.
