A small species readily distinpnished from all others of the genus 

 by its very conspicuous median prothoracic tubercle. 



The legs are sometimes infuscated in parts. The fascicles project 

 obliquely forwards ; they are l)oth small, but the inner one is con- 

 siderably larger than the outer one on each shoulder. At a glance the 

 elytra appear to have square shoulders, but the spaces where the 

 true shoulders should be are excised ; the false shoulders 

 are smooth and inipunctate at their tips. The tibiae are 

 compressed and inflated, with their outer edges rounded but not 

 angular, as in others of the genus, although from some directions 

 the front pair appear somewhat angular towards the base. The tarsi 

 are fitted into grooves in the tibiae, the tibiae into the femora, and 

 the front legs into prothoracic grooves. 



The three specimens sent by Mr. Davey (two have been returned 

 to him as co-types) are apparently females, as each has a process (ai> 

 parently an ovipositor) with two inner jirojei-tions, extruded from 

 the tip of the abdomen. 



(lihinu/(ln psiti ravicollift, n.sp. 



Of a uniform dark chestnut-brown, with rather straggling 

 stiff yellowish setae ; absent from greater portion of pronotum and 

 depression and sides of elytra : near shoulders with conspicuous 

 golden fascicles. 



Head between antennae about as long (to mouth parts) as Avide, 

 flat, finely shagreened ; with small but distinct punctures. Antennae 

 when at rest completely fitted into cavities. Frotliorar fully twice 

 as wide as the sides are long, but along middle about one-third longer 

 than sides ; these almost straight and strongly raised, front margin 

 sinuous and strongly raised, but somewhat thinner than sides ; disc 

 gently undulated and finely shagreened. Elytra decidedly wider than 

 prothorax, apices widely and separately rounded ; near base with a 

 wide, transverse, shining, irregular depression, which is continued 

 to each side, where it emerges as a narrow curved slit, but is partly
