120 NORTH AMKKICAN 



FALISCVS n. gen. 



The uni<iue species of Faliscus was taken in very moderate number 

 by Mr. E. A. Schwarz at Trenton Falls, New York, The descrip- 

 tion of this form which follows, will at the same time serve to convey 

 a more minute knowledge of its generic characters. 



1. F. 1>icanalis n. .sp. — Form robust. Pubescence rather fine, short, 

 evenly distributed, dense, very pale and somewhat conspicuous ; color of 

 body throughout rather dark piceous-brovvn, antennae and legs much paler, 

 piceo-Havate. Head rather small, much wider than long ; eyes large, promi- 

 nent, coarsely granulated, evenly convex ; genae extremely strongly conver- 

 gent, very feebly arcuate, scarcely more than one-half as long as the eye, not 

 at all prominent ; interocnlar surface moderately elevated above the eyes, 

 nearly flat above, highly polished and impunctate, having at a little more 

 than one-third the length from the base two small rather deeply impressed 

 circular foveae, mutually nearly twice as distant as either from the eye, 

 and apparently naked, also just behind the anterior angles of the front two 

 obli(jue narrow feebly impressed and clearly defined gi'ooves, which. are very 

 short and almost transverse, not meeting on the median line, but joined 

 posteriorly to the foveae by excessively feeble broadly impressed parallel 

 channels ; intermediate surface broader than long, nearly flat ; supra- 

 antennal tuberculations rather flat, each crossed by a narrow clearly defined 

 canaliculation, joined by the strongly arcuate very broadly convex frontal 

 ridge ; labrum small, scarcely twice as wide as long, broadly and extremely 

 feebly arcuate anteriorly, rounded at the sides and feebly constricted at 

 base; antennae slender, nearly two-thirds longer than the head, club very 

 long and slender, second joint longer than wide, slightly robust, third nar- 

 rower, longer than wide, four to six globular, seventh thicker than the sixth, 

 nearly globular, eighth nearly as thick as the seventh, one-third wider than 

 long, ninth one-half longer than the eighth, scarcely one-third wider than 

 long, transversely and very slightly cuueate, tenth scarcely as long as the 

 ninth, one-half w'ider than long, nearly rectangular in outline, eleventh very 

 slightly wider than the tenth, distinctly longer than wide, oval, slightly 

 acuminate at tip ; last joint of maxillary palpi rather long and slender ; 

 under surface of head having a large pad of erect sensitive setae. Prothorax 

 widest just before the middle where it is about one-sixth wider than long 

 and distinctly wider than the head ; sides broadly evenly and strongly 

 arcuate, straight toward the basal angles, very feebly sinuate for a very 

 short distance near the apex ; apex much less than one-half as long as the 

 pronotal width and two-thirds as long as the base ; lateral edges even ; disk 

 broadly convex, shining, very finely and rather sparsely punctulo-asperate, 

 having at one-sixth the length from the posterior margin a small deep longi- 

 tudinally oval punctiform impression, not spong\'-pubescent and produced 

 forward through the basal half of the pronotum as a feebly impressed canali- 

 culation, which gradually becomes obsolete ; lateral foveae wanting, but in 

 their i)lace two longitudinal broadly impressed nearly straight canalicular 

 I'liaunels, crossing the edge near the basal and apical angles, not connected
