Studies in the Tenebrionidae (Coleop.). 



By FRANK E. BLAISDELL, SR., San Francisco, California. 



The following new species are based on facts observed in 

 the field, by Messrs. Ralph Hopping and F. W. Nunenmacher 

 respectively. 



Coniontis hoppingi n. sp. 



Oblong, smooth and shining; black, frequently nigro-piceous; tibiae 

 and tarsi rufo-piceous, antennae and palpi rufous, pubescence minute 

 and inconspicuous. 



Head equal to one-half the width of the prothorax, convex be- 

 tween the eyes, vertex rather prominent, finely and sparsely punc- 

 tate, the punctures frequently denser laterally and on the epistoma; 

 fronto-clypeal suture is more or less evident, and the posterior can- 

 thus of the eye is slightly more prominent than the anterior. Antennae 

 extending to a point slightly behind the middle of the pronotum. 

 Epistoma triangularly emarginate with the angles rather narrowly 

 rounded. Setae absent. Antennae rather slender, the third joint dis- 

 tinctly twice as long as the second, the fourth to the seventh inclus- 

 ive, subequal in length and obconical, eighth to the tenth subtriangular, 

 eleventh suboval and smaller. 



Pronotum about one-sixth wider than long, base one-third wider 

 than the apex; disk evenly convex, finely and sparsely punctulate, the 

 punctules becoming slightly larger and denser laterally; apex emar- 

 ginate in circular arc, rather finely beaded, more strongly so later- 

 ally; sides subparallel in basal half, thence evenly arcuate to the apex, 

 or more distinctly arcuate to the base, bead rather strong; base as 

 wide as the elytra, emarginate, moderately lobed at the middle third 

 and sinuate laterally; basal angles slightly less than right; apical angles 

 narrowly rounded. 



Elytra rather more than one-half to almost one-third longer than 

 wide; sides snbparallel, distinctly and rather broadly arcuate in api- 

 cal third, slightly so in basal two-thirds; apices swollen and reflexed, 

 sub-tuberculate and slightly divergent; disk convex, moderately so on 

 the dorsum, strongly and evenly rounded laterally, with a tendency 

 to a slight inflexion, arcuately declivous posteriorly, sides of the de- 

 clivity more or less slightly inflated, very finely and at times sub- 

 obsoletely punctulate, setae only visible under high power. At times 

 llu're is evidence of eroded grooves, occasionally there are evanes- 

 cent corrugations. 



Proplcurae longitudinally rugose and smooth. Prosternal process 

 strongly margined and feebly convex. 



Length 14.0-15.5 mm.; width 6.5-7.5 mm.
