with irregular, not densely-placed punctures, each puncture with a 

 recurved hair, finer and longer than in the preceding species ; sutural 

 angle obtuse. Propygidium longitudinally-grooved at middle, the sides of 

 which are strongly divergent in front. Mentum as long as broad, sudden- 

 ly narrowed in front into a small process, deeply impressed in about 

 apical half. Prosternum broadly arcuate in front. Anterior tibi?e tri- 

 dentate, the upper tooth small and further removed from the second tooth 

 than from the base ; posterior femora broad at apex, and with a large, 

 slightly curved tooth ; posterior tibi^ broad and somewhat flattened ; 

 first joint of posterior tarsi elongate, not curved. Beneath sparsely 

 punctate and clothed with moderately long hairs, the last two segments 

 more densely punctate than the rest of abdomen. 



Female : Difi'ers from the male by having the hind femora and tibine 

 not as .broad and the apical femoral tooth much smaller. 



Length, 6.25-6.50 mm.

Except in some minor characters, the specimens, which I refer to this 

 species, agree well with nearly all the important ones used in separating 

 the species in this genus, as far as given in the description. By the not 

 entirely impressed mentum this species has to be placed with mandi- 

 bular is 2a^di frontalis ; from the first it differs by the form of femora and 

 tibise and the different clypeus; some of these characters separate it also 

 from frontalis, besides the different mentum. The frontal carina is at 

 best feeble, and in some specimens entirely absent. 



Ochodmis estriatus, new species. — Elongate, testaceous. Head flat, 

 unarmed, densely punctate ; clypeus very short, reflexed, clypeal margin 

 single, thickened, arcuate ; labrum strongly transverse, broadly emarginate. 

 Prothorax punctate, punctures well separated, median line impressed, 

 obsolete near apex. Elytra irregularly, not very densely punctate, without 

 strise, except an impunctate sutural, surface pubescent with fine, short 

 hairs ; sutural angles rounded. Prosternum in front subangulate at 

 middle. Anterior tibise strongly tridentate ; intermediate tibi^ strongly 

 dilated towards apex and shorter than the femora; posterior trochanters 

 prolonged into an acute process, posterior femora with a triangular, obtuse 

 tooth slightly before apex, posterior tibiae simple, broad and short, outer 

 side straight, inside arcuately widening to apex ; first jpint of posterior 

 tarsi elongate, as long as the three following joints ; spurs of middle and
