BELONUCIIUS Nord. 



B. moqilillUS n. sp. — Form rather slender, depressed. Head and 

 prothorax black, mandibles fuscous toward tips ; antennae dark fuscous, 

 piceous-black at base ; elytra and abdomen rufous, last two segments above 

 and beneath black ; pubescence of elytra and abdomen sparse, rather fine, 

 pale, not conspicuous, that of the head and prothorax in the form of very 

 sparse coarse erect setae. Head small, slightly longer than wide ; eyes 

 elongate, oval, not at all prominent, at more than their own length from 

 the base ; sides behind them feebly convergent and nearly straight, then 

 strongly and broadly rounded behind to the neck ; interocular surface feebly 

 convex, shining, extremely minutely strigato-rugulose, having two setiger- 

 ous punctures near the middle on a line through the middle of the eyes, and 

 two or three just above each eye, also a very feebly impressed median canali- 

 culation becoming stronger toward the labrum ; the latter very short and 

 broad, strongly bilobed, each lobe broadly rounded anteriorly and bearing 

 two very long and several small setae ; epistoma broadly and feebly sinuate 

 anteriorly ; mandibles long and prominent, nearly straight externally toward 

 base, arcuate at the apex ; antennae two-thirds longer than the width of 

 head, outer joints gradually and somewhat feebly incrassate and covered 

 very densely with extremely short fulvous pubescence and coarse sparse 

 erect setae, basal joint slender, four-lifths longer than the second which is 

 more than twice as long as wide, second and third equal, strongly clavate, 

 fourth very short, very slightly longer than wide, tenth scarcely longer than 

 the fourth, about one-third wider than long, eleventh obliquely produced at 

 tip ; maxillary palpi very slender, piceous-black toward base, pale reddish- 

 testaceous toward tip, fourth joint very slender, one-half longer than the 

 third ; under surface polished, excessively sparsely and minutely punctu- 

 late. Prothorax scarcely narrower than the head, just visibly longer than 

 wide ; sides nearly parallel, feebly arcuate ; base and basal angles broadly 

 evenly and continuously rounded ; apical angles inflexed, rounded ; apex 

 broadly and feebly arcuate ; disk moderately convex, polished, with two 

 straight medial rows of five punctures not attaining the base, and, on each 

 side, an exterior very irregular row of three or four punctures, also three or 

 four along the edge at each basal angle. Elytra at base distinctly wider 

 than the pronotum ; sides slightly divergent posteriorly and feebly arcuate ; 

 together broadly angularly and distinctly emarginate behind ; disk slightly 

 wider than long, shining, rather finely evenly and sparsely punctate. Abdo- 

 men diminishing but very slightly in width posteriorly ; border strongly 

 inclined, rather thin and very strong ; surface feebly and sparsely punctate ; 

 under surface more strongly so, especially along the bases of the basal seg- 

 ments where the punctures are abruptly large, deeply impressed and close. 

 Legs rather long ; anterior coxae extremely large, extremely highly polished^ 

 glabrous except near the tips, almost as long as the femora ; the latter are 

 slender and armed along the inner edge with a short row of erect stout black 

 spines just beyond the middle ; corresponding tibiae slender, armed at tip 

 with two strong very nearly equal spines and many shorter and more slender 

 spinules ; corresponding tarsi not dilated ; first joint of the posterior tarsi
