 In the above table I have omitted all reference to the terminal joint 

 of the antennae as it varies with the sex, being longer in the male.

 does not appear in the table as I am unable to separate it from 

 convexidus Lee. 



H. perforatllS n. sp. — Moderately elongate, piceous or black, moderately 

 shining. Antennae rather slender, nearlj' reaching the middle of the body, 

 outer joints scarcely wider and very little comi)ressed. Head moderately 

 denselv punctured. Thorax wider than long, apex and base equal, truncate, 

 sides moderately arcuate, a little more strongly in front of middle, margin 

 acute, hind angles sharply rectangular, disc moderately convex, coarsely ami 

 densely punctured. Elytra oblong oval, very little wider than the thorax, 

 surface with rows of large, very deeply impressed, slightly elongate punc- 

 tures, intervals narrower sparsely punctulate. Prothorax beneath with punc- 

 tures which become strigose. Abdomen sparsely punctured. Length .SO inchj 

 7. .5 mm. 



This species has some superficial resemblance to disrrefus, but the 

 rows of punctures on the elytra are not only coarser than in that but 

 also than in any other of our species. 



Two specimens from Texas, given me by Mr. A. S. Fuller. 



II. spretus n. sp. — Form oblong oval, moderately robust, black, surface 

 with slight seneous lustre. Antennae slender, attaining the middle of the body 

 % , or slightly passing the hind angles of thorax J . Head moderately densely 

 punctured. Thorax a little wider than long, base a little broader than apex, 

 sides feebly arcuate in front, nearly parallel 9 <"* slightly convergent %, 

 jnargin acute, hind angles sharply rectangular, disc moderately convex, and 

 rather densely punctate. Elytra oval slightly oblong, at middle nearly twice 

 as wide as thorax 9, less wide in %, moderately convex surface finely striate, 

 strise indistinctly punctured, intervals flat, sparsely punctulate, often wrinkled. 

 Under side of thorax coarsely and moderately densely punctured, abdomen 

 densely punctured, denser in the 9 ^lian the %. Length .36— .68 inch; 

 9 — 17 mm. 



In the 9 the last three antennal joints are much shorter than those 

 which precede, are broader and more flattened. lu tlie % the last 

 two only are a very little shorter, not broader, the eleventh being 

 fully as long as the tentli.
