204 NEW SPECIES MELYRIDAE, CHRYSOMELIDAE AND TENEBRIONIDAE 



Abdomen more or less closely and moderately coarsely punctate, 

 intercoxal process rugose and smooth at middle; segments more or less 

 transversely rugose along the sides, second segment more or less glabrous 

 in middle third, third quite glabrous at middle, fourth and fifth rather 

 more densely punctate, fourth more or less glabrous along the base ; first 

 suture straight, third and fourth strongly arcuate. 



Legs rather slender, posterior tibiae slightly inwardly arcuate ; femora 

 densely punctate throughout including the tibial grooves, punctures smaller 

 than those of the abdomen ; tibiae densely muricato-punctate ; tarsi similar 

 in the sexes, rather stout, plantar grooves open ; terminal joints of all of 

 the tarsi fringed with rather long and closely-placed ferruginous setae. 



Male unknown. 



Female. Abdomen convex and horizontal. Elytra oblong subovate 

 and moderately broad. 



Measurement. Length (Type), 23 mm. ; width, 10 mm. 



Holotype, female, in my own collection. A paratype in the collection 

 of Mr. F. W. Nunenmacher. 



Type locality. Goldfield, Esmeralda County, Nevada. Collected 

 June 16, 1908. Two females studied. 



Convexus, as compared with 'laticeps, is more convex and not so 

 broad, the body beneath is much more densely and strongly punctate, the 

 pronotum is more distinctly punctate, especially within the angles, the 

 mentum is less transverse, densely punctured, with the sides broadly 

 arcuate and the surface at apex impressed so as to make the margin 

 appear slightly emarginate. 



Schizillus nunenmacheri, new species. Form elongate, oblong-sub- 

 ovate. Color dull black, more or less opaque. Subobsoletely sculptured. 



Head very broadly and transversely but not strongly impressed 

 between the antennae and along the sides before the eyes ; central area of 

 the epistoma slightly prominent and convex ; fronto-epistomal margin 

 rather hemi-hexagonal ; surface smooth, obsoletely punctate, except on the 

 epistoma along the margin where the punctures are more or less distinct. 

 Antennae quite slender, third joint very elongate, about equal to the next 

 four taken together, joints four to eleven rather narrower than the third, 

 about twice as long as wide, tenth slightly narrower, eleventh smaller, 

 pointed-oval and about as long as wide. 



Pronotum almost a half wider than long; apex rather deeply and 

 broadly emarginate, apical angles subacute and anteriorly prominent; 

 sides feebly arcuate in anterior one-half, thence almost straight and 

 moderately convergent to the basal angles, marginal bead very fine to 

 subobsolete; base broadly and feebly emarginate; basal angles sub-
