141. Aleuas curtipennis sp. nov. 



A medium-sized brachypterous species, in which the hind temora 

 .uc more or less strongly infuscated on the lower sulcus and internally, 

 and the hind tibiae are coralline. 



Head large, about as wide (cf) or a little wider than the anterior 

 edge of the pronotum (9 ), the occiput gently arcuate about one-half 

 the length of the pronotum; eyes elongate, moderately prominent, 

 their anterior edge nearly straight, a little longer than the anterior 

 edge of the cheeks below them, separated above by a space equal to 

 the shortest diameter of one of them in the female, and by two-thirds 

 such diameter in the male. Fastigium gently depressed, somewhat 

 sulcate in both sexes. Frontal costa prominent, acuminate above, 

 the lateral walls sharp, in the female parallel from the antennae to 

 clypeus, in male slightly contracted just below the ocellus, in both 

 sulcate; facial carinae also prominent, divergent. Face feebl} 

 and sparsely punctulate, viewed in profile gently arcuate, somewhat 

 oblique. Antenna? filiform, slender, annulate, in the male as long as 

 the head and pronotum combined, in the female somewhat less. 

 Pronotum with the sides parallel, strongly rugoso-punctate, much more 

 closely so on the posterior lobe; the dorsum viewed laterally gently 

 arcuate, the median carina prominent, severed behind the middle 

 by the last transverse sulcus, the posterior margin broadly angulate. 

 Tegmina smooth, abbreviated, elongate elliptical, in the female
