rugosely punctured, coarser at base than at apex; wings grayish, veins darker. 

 Under surface more finely punctured than the upper surface. Last joint of maxillary 

 palpi slightly widening to apex and obliquely truncate, last joint of labial palpi oval. 

 Prothorax beneath broadly and deeply emarginate in front just before the front coxse. 

 Hind tibce outside longitudinally impressed at apical half. Abdomen broad, gradu- 

 ally narrowing to the sixth ventral, last segment conical. Length, 7 mm. 



One specimen in the Hubbard and Schwarz coll. U. S. National 

 Museium, taken by Mr. Schwarz, June 6, in San Diego, Texas. 



Type. — No. 8162, U. S. National Museum. 



This insect is very remarkable by the structure of the antenn;e. 

 I have called the twelfth joint compressed leaf-like, which appearance 

 it has, but it is more correct as given in the generic description, that 

 to the entire length of the twelfth joint an appendage is soldered simi- 

 lar in shape and texture to the others, given this joint the appearance 

 of a leaf like appendage of the eleventh joint. 



The apendages and tooth-like projections are much paler in color 

 than the joints. There may be some doubt as to the correctness of 

 my observation in regard of the twelfth antennal joint, but I have 

 carefully examined the antennse from every point and the specimen 

 was excellently mounted by Mr. Schwarz, and in good condition. On 

 looking from above the division between the eleventh and twelfth joint 

 could be as plainly seen as that between the tenth and eleventh. 



Cenophengus ? pallidus, new species. 



Elongate, opaque, pale yellowish ; thorax distinctly longer than wide, side 

 margin deflexed more widely at apex. Head flat, parallel, coarsely punctured, 

 moderately, densely pubescent with pale hairs ; eyes large, convex, rounded ; antennse 

 eleven jointed, biramose from the fourth joint. Thorax distinctly longer than wide, 

 narrower at apex, sides slightly arcuate, side margin broadly deflexed near apex, 

 narrow at base, basal angles variable, base slightly lobed at middle, disk alutaceous, 

 with coarse punctures, sparsely placed and not deeply impressed. Elytra short, not 

 quite half as long as the body, narrowing to apex, which is subacutely rounded, disk 

 finely granulate, punctate smoother near base. Maxillary palpi long, last joint tri- 

 angular or rather securiform, labial palpi short with last joint oval. Last ventrat 

 segment narrowly, rather deeply, emarginate. Length, 3 mm. 



Brownsville, Texas (Esperanza Ranch, June). Four specimens 

 in the Museum of the Brooklyn Institute. 



This species is not a Cenophengus according to our present classi- 

 fication, there is no acute side margin of the thorax and the last joint 

 of maxillary palpi is not cylindrical. Dr. Leconte's generic descrip- 

 tion is very short and in absence of specimens for comparison I pre- 

 fer to leave it in this genus for the present.
