SCHIZILLUS LATICEPS HORN 205 



rectangular; disk sculptureless, smooth, almost without impressions, cen- 

 tral area anteriorly rather strongly convex, elsewhere moderately so, 

 gradually declivous at the apical angles. 



Parapleura smooth and opaque, with few rugae on the coxal con- 

 vexities. 



Elytra about a half longer than wide, suboblong-oval, widest at about 

 the middle ; base feebly arcuate, quite equal to the pronotal base ; disk 

 moderately convex, more strongly and rather broadly rounded at the sides, 

 obliquely declivous posteriorly; apical lobe moderate and not broadly 

 rounded ; surface smooth and dull, striae obsolete or very faintly evident 

 when viewed obliquely, interstices with a row of rather small muricate 

 tubercles ; these are obsolete along the suture, becoming gradually stronger 

 laterally and on the apical declivity. 



Epipleura smooth and without sculpturing. 



Sterna. Prosternum obsoletely rugose anteriorly and on the process, 

 the latter a little produced, suboval with the sides converging slightly 

 behind the coxae, tip rather broadly rounded, marginal bead not evident ; 

 surface longitudinally impressed along the middle, with few punctures 

 along the margin. Mesosternum not sculptured, declivous anteriorly, 

 broadly impressed at middle, sides prominent and subtuberculate. Meta- 

 sternum rugose at middle, smooth laterally. 



Parasterna sculptureless, or with a few fine obsolete punctures. 



Abdomen obsoletely sculptured; a few very fine punctules more or 

 less evident, few coarse punctures behind the coxae; fifth segment with 

 very small indistinct punctures. 



Legs rather slender, anterior pair apparently a little stouter. Femora 

 and tibiae rather densely but not strongly sculptured throughout including 

 the tibial grooves, the former punctate, the latter muricato-punctate. 

 Tarsi without doubt similar in the sexes, rather stout, plantar grooves 

 open, setae ferruginous; terminal joints of all the tarsi fringed with 

 closely placed ferruginous setae. 



Male unknown. 



Female. Abdomen convex and horizontal. 



Measurements Length, 18.2 mm. ; width, 8 mm. 



Holotype a female in my collection. Collected on Aug. 14, 1908, by 

 Mr. F. W. Nunenmacher. 



Type locality and habitat. Goldfield, Esmeralda County, Nevada. 



Nunenmacheri is distinct in its obsolete sculpturing, long third an- 

 tennal joint and less rounded sides of the pronotum. The mentum is 

 smooth and partly hidden by dried regurgitated ingesta. This species is 

 suggestive of Cryptoglossa laevis on account of its smooth integuments, 

 with the exception of the elytra ; it is more elongate and less robust, the
