only about the extreme base, appears to indicate that the type 

 is a female. The tip of the club is slightly infuscated. Nearly 

 all species of the genus have variable clothing ; on the type, 

 evidently in perfect condition, the scales on the head are almost 

 entirely white and fairly dense ; the rostrum is glabrous except 

 at the extreme base ; on the prothorax each side is densely 

 clothed with white scales, elsewhere dark chocolate-brown 

 scales are dense, but mixed with a few pale ones ; on the elytra 

 the white scales are denser on the apical slope than elsewhere, 

 on a dilated space on the suture before same they are dark, 

 on other parts of the elytra the scales have a somewhat 

 mottled or feebly lineate appearance ; on the under-surf ace 

 and legs the scales are silvery, but with a rosy flush in places, 

 and slightly greenish on and about the coxae. 



Myrmacicelus pilosicornis, n. sp. 



Deep black. 



Read with minute punctures. Eyes large and close 

 together. Rostrum lightly curved, about as long as front 

 femora ; with dense and rather fine punctures, larger on sides 

 at base than elsewhere. Antennae with apical two-thirds 

 clothed with conspicuous and rather long hairs ; scape short ; 

 first joint of funicle distinct but transverse, the others very 

 short and closely applied ; club longer than funicle and scape 

 combined, rroihorax much longer than wide, sides rounded 

 on apical two-thirds ; disc with small but sharply defined punc- 

 tures, becoming larger on sides ; base depressed, narrow, sub- 

 opaque, and with crowded punctures. Elytra subopaque and 

 finely shagreened ; with very feeble remnants of striation. 

 Legs rather long and stout ; claw joint projecting well beyond 

 lobes of third. Length, 3^-4 mm. 



IIah.—¥\d.t Rock Hofe. Type, I. 5183. 



The subopaque elytra and base of prothorax, with the very 

 different clothing of antennae, readily distinguishes from all 

 previously described species of the genus. 



AULETES TIBIALIS, n. Sp. 



Deep black, but in places with a vague brassy gloss; knees 

 and tibiae more or less reddish. Upper-surface with moder- 

 ately long and almost uniform ashen pubescence, becoming 

 shorter on under-surf ace. 



Head evenly convex; with moderately dense and small, 

 but sharply defined punctures. Eyes very prominent. Ros- 

 trum rather long, slightly dilated to apex ; with fairly coarse 

 punctures and an impressed line at base, elsewhere with much 

 smaller punctures. Antennae long and thin, inserted almost 

 at extreme base of rostrum. Prothorax almost as long as
