lighter in color; antennae dark distad; forewings semitrans- 

 parent, usually brownish or sometimes brown and opaque. 



Head strongly declivous, fully as broad as thorax. Vertex a 

 little more than half as long as broad, subperpendicular to axis 

 of body, with a shallow sulcus across posterior portion, surface 

 somewhat convex. Frons visible in front, with large ocellus. 

 Genae swollen beneath antennal bases into subconical processes 

 very broad at base, subacutely pointed and about one-third as 

 long as vertex. Antennae a little less than twice as long as 

 width of head, slender. 



Thorax not strongly arched. Legs rather short, hind tibia? 

 with a small spur at base. Forewings long and narrow, sub- 

 acute at apex, membrane thick, semitransparent or often opaque 

 because of the brown color. 



Abdomen long. Male forceps slender, little more than half 

 as long as anal valve, acutely pointed ; anal valve long and rather 

 slender, tapering from base to subacute apex. Female genital 

 segment about half as long as abdomen, dorsal valve with a 

 large, rounded convexity dorsad, acutely pointed, a little longer 

 than ventral valve. 



Moluccas, Amboina (Muir), 1 male and 3 females. 



This resembles P. magnifrons, a tropical American species, 

 more closely than other species of this genus. Quite possibly 

 these two species should be referred to a distinct genus. 



Genus HETERONEURA novum 



Head somewhat as in Pauropsylla, much deflexed and short; 

 vertex roundly convex; frons inferior, with anterior ocellus 

 visible only from in front; gense small, not much swollen, cones 

 wanting; eyes rather small; beak short; antennae as long as 

 width of head or longer. 



Thorax well arched; legs short, front tibiae flattened, thin and 

 foliaceous; hind tibiae with a tooth near apex; metacoxal spurs 

 short. Forewings coriaceous, opaque, broad; marginal cells 

 long and narrow as in Paurocephala ; second marginal cell flexed 

 toward costal margin; radius contorted; pterostigma closed. 



Type of the genus, Heteroneura oceanica sp. nov. 



This genus appears to belong to the subfamily Pauropsyllinae, 

 but differs from other genera of this subfamily in the coriaceous 

 forewings, the much contorted radius, and the foliaceous front 

 tibiae.

Length of body, 1.8 millimeters ; length of fore wing, 2 ; length 

 of antennae, 1.2. General color dark brown; meso- and meta-
