the posterior but little more than one-half as long as the tibise, with 

 the first joint just visibly longer than the second or third, the latter 

 scarcely longer than wide. 



This genus is closely allied to Leptusa, but differs in the longer 

 antennae with much shorter third joint, in the longer head and 

 labrum, in the bifid ligula and very short fifth segment of the 

 abdomen, which is not perceptibly more than one-half as long as 

 the fourth ; also in the more robust tarsi and minute size. 



A. pallens n. sp. — Pale rufo-testaceous tliroughout, tlie fourth dorsal 

 segment piceous-black ; iiitegumeiits slightly reticulate, feebly shining, the 

 abdomen polished ; head, pronotum and elytra very minutely and scarcely 

 visibly punctulate ; abdomen more sparsely but not distinctly so ; pubescence 

 sparse but long, coarse and distinct. Head rather longer than wide, a little 

 narrower but longer than the prothorax, convex, even ; sides parallel and 

 evenly arcuate ; antennse as long as the head, prothorax and elytra, pale 

 throughout. Prothorax one-third wider than long, the sides broadly, feebly 

 arcuate, more convergent and nearly straight in basal half, the basal angles 

 very obtuse but not rounded ; apical deflexed, right — viewed laterally — not 

 rounded ; base yery feebly arcuate, slightly narrower than the apex ; disk 

 convex and declivous at the sides, more flattened above, with a broad region 

 along the middle which is very feebly impressed, more distinctly so toward 

 base and densely granulato-reticulate and opaque throughout. Elytra dis- 

 tinctly wider than long, parallel and straight at the sides, just visibly longer 

 and fully one-fourth wider than the prothorax, the humeri distinctly exposed 

 and transverse at base. Abdomen as long as the anterior parts, behind the 

 middle as wide as the elytra, but at base distinctly narrower ; sides scarcely 

 perceptibly arcuate ; border moderate, not thick ; surface transversely convex 

 behind. Legs short. Length 1.25 mm. ; width 0.3 mm. 



Florida. 



In the male the fifth ventral plate is transverse at apex, with a 

 short acute spicule projecting horizontally from the middle of the 

 edge, the sixth lobed in the middle, 



SIPALIA Rey. 



This genus seems to be distinct from Leptusa although closely 

 allied. 



S. frontalis n. sp. — Parallel, thick, rather convex, shining, the abdomen 

 polished, rufo-testaceous, the antennse dusky except at base ; abdomen pice- 

 ous, the fifth segment and apices of the first three, pale ; pubescence coarse, 

 sparse but rather long and distinct ; head and pronotum extremely finely, 

 feebly but rather closely punctulate ; elytra coarsely, more sparsely and 

 asperately punctate ; abdomen sparsely so. Head orbicular, convex, slightly
