between the fine dense punctuation of the anterior parts, and the 

 coarser, beautifully regular sculpture of the abdomen, is very 

 marked. 



RHEOCflARA Rey. 



The species described below is assigned provisionally to this 

 genus, although the outer joints of the antennae are strongly trans- 

 verse, the first three tergites gradually less strongly impressed at 

 base, the posterior tarsi much shorter than the tibiae, and the ante- 

 rior tibiae entirely devoid of spinules. It will probably form a genus 

 distinct from Rheochara, but at present it is not advisable to sepa- 

 rate it, as I have no representative of Rheochara with which to 

 compare it. 



K* lucifllga. n. sp. — Slender, moderately convex, pale ochreous-yellow, 

 the head piceous and the abdomen with a large very feeble piceous cloud near 

 the apex ; apices of the three basal segments paler than the base ; surface 

 feebly shining, the abdomen polished ; pubescence rather coarse, decumbent, 

 moderately dense, sparser on the abdomen. Head ovulate, longer than wide, 

 three-fifths as wide as the prothorax, evenly convex, finely, sparsely punctate ; 

 eyes moderate, before the middle ; infralateral ridge very strong ; ligula with 

 a short thick simple and membranous deflexed process bearing two setse ; 

 terminal supplementary palpal joint distinct ; anteunse as long as the head 

 and prothorax, thick, the first three joints gradually decreasing in length, 

 four to ten transverse, increasing greatly in size, the tenth rather strongly 

 transverse, eleventh large, feebly pyriform, as long as the two preceding, 

 outer joints somewhat perfoliate. Prothorax one-fourth wider than long, sides 

 subparallel, broadly arcuate, distinctly convergent only in apical third ; base 

 broadly arcuate, much wider than the apex ; basal angles very obtuse but 

 not obliterated ; disk widest just behind the middle, broadly, feebly convex, 

 finely feebly and somewhat closely punctate, not in the least impressed, the 

 edges, except at apex, finely beaded ; hypomera slightly visibly from the sides, 

 subhorizontal. Elytra one-half wider than long, not distinctly wider and a 

 little shorter than the prothorax ; sides subparallel, feebly arcuate ; humeri 

 rounded, slightly exposed ; disk rather finely but strongly, somewhat closely, 

 subasperately punctate ; suture strongly margined, scarcely impressed. Abdo- 

 men — when extended — not quite twice as long as the anterior parts, very 

 slightly narrower than the elytra; sides just visibly convergent behind the 

 middle ; fourth segment a little shorter than the fifth, the latter very remotely 

 punctate ; basal impressions not more densely or coarsely punctate. Legs 

 moderate ; posterior tarsi much shorter than the tibia, slender, with the basal 

 joint fully as long as the next two. Length (extended) 4.8 mm. ; width 0.9 mm.

 pointed, extending to and over the acute apex of the mesosternal
