of small spots in costal membrane, the stigma, and a broad 

 irregular longitudinal suffusion from base to apex, the 

 venation also fuscous brown ; wings very pale fuliginous, 

 the veins darker; vertex longer than broad, the margins 

 strongly carinate ; margins to pronotum carinate ; mesonotum 

 with five central longitudinal carinations ; face centrally 

 and marginally strongly carinate, the central carinatiou 

 bifurcate at apex ; clypeus centrally and marginally carinate; 

 female with a long central abdominal apical appendage ; 

 posterior tibise with a distinct spine near middle.

Adzapala, gen. no v. 



Head moderately large and prominent, eyes large, longer 

 than broad, vertex longer than broad, distinctly concave, the 

 lateral margins carinate; face large, posteriorly about as 

 broad as long, centrally longitudinally carinate, the carina- 

 tion anteriorly bifurcate, the anterior margin about half the 

 breadth of the posterior margin, a distinct transverse incision 

 level with the posterior margins of the eyes, before clypeus 

 distinctly concave, an ocellus on each side near posterior 

 margin ; clypeus large and broad, almost as long as face, 

 centrally carinate ; pronotum very short, strongly straightly 

 angulate ; mesonotum large, considerably longer than head 

 and pronotum together, with five central carinations ; abdo- 

 men broad and robust ; posterior tibiae strongly spined near 

 middle ; tegmina more than twice as long as broad, distinctly 

 angulately sinuate beyond clavus, claval vein not extending 

 much beyond the middle of clavus, stigma large, inwardly 

 convexly rounded, two waved series of transverse veins, one 

 beyond middle, the other nearer apex, thus defining re- 

 spectively apical and anteapical cells, apical margin rounded ; 

 wings shorter and at base about as broad as tegmina^ two 

 oblique discal transverse veins beyond middle. 



This genus by the five carinations to the tegmina is allied 

 to both Oliarus and Mnemosyne, from both of which it differs 

 by the structure of the face and the sinuate tegmina beyoud 

 the apex of clavus. 



Adzapala greeni, sp. n. 



Vertex dull ochraceous, eyes piceous ; pro- and mesonota 

 piceous, the carinations to the latter testaceous ; abdomen 

 above fuscous brown, the lateral areas ochraceous ; face
