with which I place it for the present, rather than create a possible 

 synon3'm. 



Teretriosoma sexualis, new species. 



Subcylindrical, metallic green or blue, above somewhat coarsely not closely punc- 

 tate, beneath more coarsely punctate, antennae and legs reddish. Head between the 

 eyes convex, at middle transversely sulcate and finely pubescent, below this sulcation 

 very deeply excavated. Thorax withthe stria close to the margin, entire, the punc- 

 tuation at apex a little finer and closer than near base. Baasl margin of elytra smooth, 

 transversely impressed, faint on the disk, very deeply so and continued along sides 

 to the middle of the humeral umbone, which is impunctate. Pygidium at middle 

 acute, convex above, beneath concave. Prosternum truncate in front, longitudinally 

 impressed on each side, not striate. Mesosternum semicircularly rounded in front, 

 margined. Anterior tibiae with eight, middle tibiK with seven, hind Uh'ive with five 

 spines. Length, 2 mm. 



Two specimens, Brownsville, Texas, in the Museum of the Brook- 

 lyn Institute. 



I place with this species two specimens, which agree well with the 

 type except that the front of head is convex and the pygidium more 

 produced and which I regard for the present, according to th views 

 expressed under chalybceiim, as females. These supposed females are 

 according to the description very close to T. conigerum Lewis described 

 from an unique specimen from Guatemala but there is a difference in 

 the number of spines of the tibiae * the underside is not strigose-rugose 

 and the abbreviated post-humeral stria, which is confluent with the 

 basal impression, and when present in conigerum would have been 

 mentioned in the description as to the presence or absence or number 

 of striae much importance is given in distinguishing species. 



Teretrius levatus Horn. 



I refer specimens which occurred frequently on dead branches of 

 Acacia farnesiana at Brownsville, to Horn's levatus. They agree well 

 with specimens collected in lower California by Mr. Beyer, except 

 that in the Texas specimens there is a very small additional spine on 

 the front tibiae ; size, form, sculpture are the same. It occurs also in 

 S. Diego, Tex. and in Arizona where it was taken by Mr. Schwarz. 



Camptodes texanus, new species. 



Rounded, convex, testaceous, head, thorax and scutellum piceous shining, fading 

 into rufous at sides of thorax and apex of clypeus, elytra greenish black. Labrum 

 feebly lobed, the lobes i^ounded, not dentate. Thorax twice as broad as long, narrow- 



*I have counted all the spines situated on the outer edge of the tibiae.
