and closely punctate ; metasternum rather finely punctate at middle, coarsely 

 at sides ; abdomen finely and rather sparsely punctate at middle, punctures 

 much larger at sides. Length 13.5 mm. Width 3.75 mm. 



Arizona, one male (coll. Dietz). 



This species is readily distinguished from similar species by the 

 feebly impressed and partly obliterated elytral striae and shorter 

 antennae. 



Trichophorus arizonensis new species. 



Elongate, rufo-castaneous ; underside, antennae and legs scarcely paler. 

 Head moderately coarsely and closely punctate ; antennae reaching a little 

 beyond the basal angles of prothorax; third joint a little longer than second, 

 both together slightly shorter than the fourth joint. Prothorax slightly 

 longer than wide at base ; sides slightly converging towards apex and near 

 apex feebly arcuate ; hind angles acutely carinate ; surface with moderately 

 coarse punctures. Elytra not quite two and one half times as long as the 

 prothorax at base, punctate-striate, intervals rather flat and somewhat closely 

 punctate, rugose near base. Prothorax beneath coarsely punctate ; meta- 

 sternum coarsely punctate, finely at middle ; abdomen coarsely punctate on 

 the first three segments at sides, finely at middle. Length 15 mm. Width 

 3.5 mm. 



S. Rita Mts., Arizona, one male (Marsden). * ' 



This species resembles siihstriatus, described above, very much, 



but is a narrower and more elongate insect with longer antennae and 



distinct elytral striae. 



Trichophorus variatus new species. 



Elongate, dark castaneous to rufo-castaneous, underside, antennae and 

 legs slightly paler. Head coarsely and moderately closely punctate ; antennae 

 reaching a little distance below the hind angles of prothorax, third joint a 

 little longer than second and both together a little shorter than fourth. 

 Prothorax as long as wide at base; sides rather feebly converging to apex; 

 hind angles acutely carinate ; surface not densely nor coarsely punctate. 

 Elytra about two and one half times as long as prothorax; punctate-striate; 

 intervals feebly convex, not very closely punctate and scarcely rugose near 

 base. Prothorax beneath coarsely punctate, punctures generally rather widely 

 separated ; metasternum and abdomen more finely punctate than prosternum. 

 Length 1 5 mm. Width 4.2 nini. 



Brownsville, Texas (Schaefifer). 



This is rather a common insect near Brownsville from May to 

 August and a variable species regarding size and color. The smaller
