Dec, 1908.] SCHAEFFER : NEW RHYNCHOPHORA. 217 



8. Alternate elytral intervals not elevated; general color grey einereus 



Alternate elytral intervals more or less elevated ; scales of upper surface brownish, 



with a more or less metallic lustre subtropicus 



9. Scales on underside and legs greenish metallic, feebly so on the upper surface ; 



beak sharply triangularly emarginate at apex ; anterior femora scarcely longer 

 than the others submetallicus 



CURCULIONID/E. 



Endalus robustus, new species. 



Color as in limatulus, but the beak is stouter and scarcely curved and densely, 

 rather coarsely punctate. Antennae inserted at apical third. Eyes separated by a 

 little more than their own width. Prothorax about twice as wide as long ; sides evenly 

 moderately strongly arcuate, apex constricted ; surface more coarsely punctate than in 

 limatulus. Elytra wider than the prothorax ; humeri obliquely rounded ; sides feebly 

 narrowing to apical fourth ; punctures of the striae elongate ; intervals flat, rather 

 sparsely and finely punctate, each with a row of large, more distant punctures, each 

 puncture bearing a short white seta. Underside covered rather densely with dirty- 

 grey scales. Length 4 mm. 



Brownsville, Texas. 



This species has a shorter elytra than the male of limatulus, 

 a different shaped and more strongly punctate prothorax, a stouter, 

 flatter beak and more widely separated eyes. 



Thysanocnemis balaninoides, new species. 



Pale rufo-testaceous, scales yellowish-white. Peak as long as head and pro- 

 thorax ; narrow, cylindrical ; on each side striate ; strise punctate. Antennae inserted'' 

 slightly below middle; the first funicular joint as long as the two following. Pro- 

 thorax twice as wide as long, sides very feebly arcuate, at about apical third arcu- 

 ately narrowing to apex ; the latter moderately constricted ; surface rather densely 

 clothed with transversely directed yellowish-white scale-like hairs. Elytra wider than 

 the prothorax ; humeri obliquely rounded ; surface moderately densely clothed with 

 yellowish- white, elongate narrower scales ; each interval with a row of rather sparsely 

 placed, wider, elongate scales. Body beneath clothed with pale, oval scales ; last, 

 ventral with a shallow, elongate median impression; pygidium rather convex. An 

 terior tibiae narrower and straight inside. Length 3 mm. 



Brownsville, Texas, one male. 



The very pale color, the narrow, cylindrical, rather longer beak 

 and the narrowly separated eyes distinguishes this from our known 

 species. In the formation of the head and beak it resembles species 

 of the genus Balaninus. 



Tychius griseus, new species. 



Form of tectus ; black, moderately densely clothed with narrow, hair-like, yel- 

 lowish-cinereous scales, beneath with broader white scales. Beak rather short, 

 scarcely as long as the prothorax, of nearly equal width throughout, except at the
