LEPTUSA Kraatz. 



, The first species here described seems to be truly congeneric 

 with the European anaiis, but has the prothorax much smaller and 

 narrower, the elvtral humeri being exposed at base. 



I/, 'brevicollis n. sp. — S!end«i-, subparallel, rather convex, shining, 

 the abdomen still more polished, dark red-brown ; legs paler, moi-e flavate ; 

 antenna concolorous ; head piceous ; abdomen brighter rufous, with a black 

 subapical cloud ; head and pronotum very feebly punctulate ; elytra coarsely, 

 somewhat rugosely but not at all asperately so ; abdomen finely and sparsely ; 

 pubescence sparse but rather long, subrecumbent and distinct. Head orbicu- 

 lar, convex, much wider than long, distinctly narrower than the prothorax, 

 the eyes rather large and prominent, at less than their own length from the 

 base ; labrum truncate ; antennae as long as the pronotum and elytra, moder- 

 ately incrassate, second and third joints elongate, subequal, fourth obconical, 

 as long as wide, four to ten gradually wider, the latter nearly twice as wide 

 as long, eleventh rather small, not longer than the two preceding. Prothorax 

 transverse, fully three-fourths wider than long, widest at two-fifths from the 

 apex where the sides are narrowly rounded, thence convergent and feebly 

 arcuate to the apex, equally convergent and broadly sinuate to the basal 

 angles, which are obtuse but sharp, the apical deflexed but also not at all 

 rounded ; hypomera extending to the apex ; base transverse, equal to the 

 apex ; disk strongly convex, extremely obsoletely impressed along the middle 

 and transversely before the scutellum. Elytra large, parallel, slightly wider 

 than long, one-fourth wider and one-half longer than the prothorax ; sides 

 nearly straight ; humeri exjjosed at base ; suture finely beaded. Abdomen 

 parallel and straight at the sides, much narrower than the elytra, as wide as 

 the prothorax ; only the first three segments strongly impressed at base ; fifth 

 distinctly longer than the fourth. Legs rather long, slender ; posterior tarsi 

 short, with the first joint distinctly longer than the second. Length 2.1 mm. ; 

 width 0.55 mm. 



Pennsylvania. 



The type is a male, the fifth dorsal plate having a small feeble 

 longitudinal carina in the middle. The labial palpi are apparently 

 three-jointed, but the first is small and anchylosed to the second, 

 which is subequal to the more slender third ; the process of the 

 ligula is slender, parallel and simple at apex. The metasternum is 

 large and long, with the side-pieces very narrow and parallel — 

 quite different from the form occurring in Sipalia. The middle 

 acetabula are deep and sharply limited by an acute beaded edge, 

 except for the extremely short distance between the apices of the 

 sternal processes, of which the mesosternal is acutely produced to 

 the middle with its apex slightly blunted, the coxa? quite appre-
