Oct., '04] ENTOMOLOGICAL NEWS. 28 1 



Size rather small, form elongate fusiform, the dorsum very distinctly 

 arched. Head with the vertex declivent, the acute fastigial process 

 directed forward and downward, somewhat depressed, apex rather 

 blunt ; interspace between the eyes broad ; eyes sub-trigonal, not promi- 

 nent ; antennae approximately twice as long as the body ; fifth palpal 

 joint slightly longer than the third, slender, the apical two-thirds with the 

 axis at an obtuse angle with the basal third. Pronotum strongly convex 

 in transverse section ; anterior and posterior margins truncate, lateral 

 lobe with the inferior margin subtruncate. Mesonotum and metanotum 

 with their exposed portions subequal ; posterior margins subtruncate ; 

 lateral lobes with the inferior margin obliquely truncate, extending con- 

 siderably below the level of the pronotum ; surface of the mesonotum 

 almost as smooth and glabrous as the pronotum, metanotum with the 

 anterior portion glabrous, but bearing a transverse series of numerous 

 low obscure tubercles. Abdomen somewhat compressed ; posterior 

 portion of the ventral surface of each segment ornamented with trans- 

 verse series of irregularly sized tubercles, more distinct and more numer- 

 ous than on the metanotum ; cerci rather short, hardly as long as the sub- 

 genital plate ; subgenital plate broad, apically with two distinct cariiKL- 

 extending from the base of the styles half way to the base, apical mar- 

 gin broadly and shallowly emarginate ; styles thick, short, apically acute. 

 Anterior femora a third again as long as the pronotum, anterior margin 

 with a single pre-apical spine, posterior margin unarmed. Median 

 femora slenderer than the anterior but of the same length, anterior 

 margin with a single pre-apical spine, posterior margin with a slender 

 genicular spine, a distinct pre-apical spine, and several smaller depressed 

 spines. Posterior femora about as long as the head and body united, 

 considerably inflated, slightly more than three times as long as broad, 

 external inferior margin very minutely serrulate ; internal inferior margin 

 very distinctly serrulate, except in the genicular portion ; tibia; about 

 one-tenth longer than the femora slightly sinuate in the proximal half, 

 four pair of spars present, minor serrations distinct and sharp, calcaria 

 with the medium pair over twice the length of the others, under surface 

 with six paired adpressed spines on the apical section ; metatarsi slightly 

 longer than the remaining tarsal joint? combined, second over twice the 

 size of the third. 



General color ochraceous and ochraceous-buft marbled and finely 

 sprinkled with blackish brown ; posterior femora with the scalariforrn 

 markings distinct, and the posterior tibia; rather imperfectly annulate.
