asserting that liis specimen was a male and resembled BoiJirio 

 thorax in some respects it may rightfully belong here, althongh 

 the venation apparently is quite different, but perhaps not more 

 so th^ sometimes occurs in opposite sexes within certain 

 genera.^ Cameron states that this species was found by 

 Blackburn on several Islands, and if still present in the Isl- 

 ands and in our collections it can hardly be anything l)ut 

 BJepyrus, although I am quite unable to reconcile Blepyrus 

 with Cameron's description. 



Quaylea n. g. 



Female : Head moderately thick, with the dorsal surface strongly 

 convex, the face refiexed but the frons not prominent ; in side view 

 appearing triangular except that the dorsal side is rounded, the facial 

 and dorsal sides subequal and considerably shorter than the occipital 

 side ; in frontal view appearing fully rounded above but becoming some- 

 what narrowed towards the mouth below the eyes ; occiput slightly 

 concave, with the neck inserted at the center ; eyes medium-sized, touch- 

 ing the occipital margin posteriorly, and descending half way to the 

 oral margin as seen in frontal view of head, in shape subtriangular with 

 bulging sides and wider anteriorly, the inferio-posterior margin longest, 

 the other two sides subequal ; f rontovertex moderately narrow, about 

 two and a half times as long as wide and a little narrowed at the 

 anterior ocellus ; ocelli rather large, in an actue-angled triangle, the pos- 

 terior pair touching the eye-margins and about their own diameter from 

 the occipital margin, the anterior ocellus at the center of the fronto- 

 vertex ; cheeks about as long as the width of the eyes, with a short, 

 delicate genal suture descending from the eyes ; face about as wide as 

 long, and as long as one-half of the head, the oral margin moderately 

 wide and arched from side to side, the antennae separated by a low, 

 rounded longitudinal ridge, the scrobes in the form of short, rather 

 broad and deep impressions converging above and meeting acutely 

 between the anterior corners of the eyes. Antennae inserted rather 

 far apart and near the clypeal margin, rather short and slightly clavate ; 

 scape short or hardly reaching beyond the facial inflexion, compressed 

 but not expanded beneath, the radicle joint about a third as long as the 

 scape proper; pedicel of usual shape and a little less than twice as long- 

 as the first funicle joint, funicle joints except the last somewhat longer 

 than wide and increasing slightly in thickness distad, the first joint 

 shortest, the sixth about as wide as long; club oval, three-jointed, a little 

 wider than the funicle and as long as the last three funicle joints com-

 the description of the male of Eitcyrfus barbatus above.
