672 Coleopterological Notices, VI. 



Seii-beaches of New Jersey and Delaware. This species very 

 greatl}^ resembles texanus, but is rather larger and with more dis- 

 tant punctures, those toward the base of the pronotum especially 

 being less densely crowded. An essential similarity- of the sexual 

 characters is as^um^d, as there is no specimen before me which is 

 in condition for observation in this regard. 



The eastern examples, previously' regarded by me as belonging 

 to Anth. californicus,a.re to be referred to the present species, the 

 resemblances throughout the genus being very great, as before 

 remarked. 



3. T. iniiiius n. sp. — Moderately slender, hij;lily polished, pale rufo- 

 testaceous, the legs andanteniiie throughout i)ale; abdomen black; elytra black- 

 ish at apex, and with a large blackish cloud at the middle of each. Head 

 about as long as wide, convex, evenly rounded behind, finely but strongly, 

 rather sparsely punctate, the eyes moderately large, prominent; antennae very 

 nearly as long as the head and prothorax, slender, only very feebly incrassate, 

 the penultimate joint rather longer than wide. Prothorax scarcely as wide as 

 the head, rather longer than wide, moderately convex, finely but strongly 

 punctate, the punctures rather dense toward the median line especially toward 

 base, the basal tubercles distinct; anterior lobe widest and strongly rounded 

 near the apex, the posterior rather less than one-third the tot<il length; con- 

 striction acute. Elytra three-fourths longer than wide, somewhat less than 

 twice as wide as the prothorax, decidedly wider a little behind the middle 

 than at base, the apex moderately broadly rounded and oblique, the sutural 

 angles slightly rounded ; disk rather coarsely punctate, the punctures some- 

 what close toward the suture; omoplates small but ((uite distinct; pubescence 

 short but stiff, sparse biit pale throughout and distinct. AlxJomcn moderately 

 shining, the legs rather slender. Length 2.4-2.75 mm. ; width 0.75-0.8 mm. 



Wyoming (Cheyenne); New Mexico (Coolidge). 



The male has the fifth ventral but little longer than the fourth, 

 with a large rounded discal impression which is more shining 

 than the general surface, the genital segment broadl3- impressed 

 throughout the width, and with the apex arcuatel}' but rather 

 strongly sinuate in the middle ; terminal knob of the gradually 

 narrowed copulatory sheath transverseh' expanded, with the lat- 

 eral extremities posteriorly hooked.

Polished, rufo-testaceous, the head blackish; elytra clouded

 varying to entirely black. Head finely but strongly, sparsely
