punctures somewhat larger and deeper. Ventral surface moderately 

 punctate, prosternum and base of ventral segments rugose. Femora 

 rugosely punctate, the posterior ones reaching the apex of elytra. 



Length 19 mm. 



Type No. 4170, U. S. N". M. Two examples, from Los 

 Angeles County, California, collected by Mr, D. W. Coquillett. 



The species resembles in form C. dilaticollis, Mannerheim, 

 but is abundantly different by the thorax and elytra being strongly 

 convex and rugose. 



Conibius rotundtcollts, n. sp. Robust, oblong, convex, smooth, piceous, 

 black, feebly shining. Head transverse, prominent at the sides before the 

 eyes, strongly punctate; epistoma broadly emarginate ; antennae very 

 robust, shorter than thorax, slightly incrassate to apex, third joint a little 

 longer than fourth. Thorax one-half broader than long; apex truncate 

 with the angles obtuse, sides scarcely depressed, strongly rounded, with 

 a fine reflexed margin, not fimbriate, posteriorly arcuate, without angles; 

 base broadly, feebly rounded ; disc rather finely and sparsely, at the sides 

 more coarsely and densely punctate, with a smooth median line. Elytra 

 ovate, widest one-fourth from the base; humeri margined, obtusely 

 rounded; surface distinctly alutaceous, with regular series of fine punc 

 tures, intervals entirely flat, with still finer irregularly scattered punctures. 

 Epipleura; broad, smooth. Abdomen polished, sparsely and finely punc- 

 tulate. Legs robust. Anterior tibiae strongly and gradually widened to 

 apex, convex above, flattened beneath, the outer apical angle slightly 

 obtuse, not at all rounded, the outer edge and hind surface denticulate. 

 Tarsi short, slender. 



Length 4 mm. Type No. 4171, U. S. N. M. 



One example from San Diego, Texas, collected (April 29, 

 1895) by Mr. E. A. Schwarz. This specimen is nearest allied 

 to Notibius gagates Horn, which is placed in the genus Conibius 

 by Capt. Casey, but the dilated anterior tibiae and rounded thorax 

 will require a new subgenus according to his arrangement. 



Ancedus texanus, n. sp. Elongate oval, depressed, ferruginous, darker 

 above, sparsely clothed with rather long erect hairs. Antennae slender, 

 second joint short, third equal to fourth, last joint but slightly longer and 

 wider than the preceding one. Eyes large, separated by a little more than 

 their own width, viewed from above. Front very coarsely punctate at 

 the sides, smooth along the median line. Thorax twice as broad as long, 

 as wide as elytra at base, apex truncate with rounded angles ; sides strongly 

 rounded, subangulate at middle, sinuate behind, the margin feebly re- 

 flexed ; base broadly rounded at middle, feebly sinuate near the sides with 

 an impressed smooth fovea in front of the sinuation; hind angles rectan 

 gular, not prominent; disc feebly convex, very coarsely rather densely 

 punctate, the intervals polished. Elytra feebly shining, densely punctate,
