COLEOPTERA 



395 



The antennae are rather stout and short, the iourth joint not loneer than broad, 

 the fifth a Httle longer, the third about as long as these two and half the sixth together, 

 terminal joint rather long, stout. Thorax strongly transverse, diftering from the species 

 grouped round D. obtitsns by the less developed hind angles, rather closely and coarsely 

 punctured, not shining. Elytra distinctly striate, the interstitial punctuation rather coarse. 

 [Co.xal laminae falling very distinctly short of the first ventral suture.] Tarsi slender, 

 their last joint small. The character drawn trom the hind coxae may possibly be due 

 to the disarticulated condition ot the specimen.

(23) Droniaeolns sputator, sp. now 



Robustus, sat latus, piceo-niger, vel piceo-rutus, crebre subtiliter punctatus, dense 

 flavo-pubescens, subopacus ; antennis, modice elongatis, pedibusque sordide testaceis, 

 prothorace elongato et lato ; tarsis angustis. Long. 8 — 8^ mm. 



Much narrower than D. ohtusus, and with the antennae different from those of 

 D. brachycerus. They are rather slender, and about one joint extends beyond the thoracic 

 angle ; the tourth joint is rather longer than broad. The thorax is long, not much 

 narrowed in front and distinctly broader than the elytra. The striation on the elytra 

 moderately deep. The tarsi are more slender in this species and in D. inolokaiejisis 

 than in any of the other large .species. Two specimens, found in fallen decaying acacias.

(24) Droiiiaeoliis luololokaieiisis. sp. no\'. 



Convexus, crassus, haud elongatus, piceus, baud nitidus, tlavo-pubescens, antennis 

 pedibusque rufis, illis haud elongatis, parum crassis. Long. 7-J^ mm. lat. fere 3 mm. 



Allied to D. obtitstis and clateroidcs : of very convex form, and readily distinguished 

 from the two species by its smaller antennae and more slender legs. The antennae are 

 rather slender, and do not extend backwards quite so far as the thoracic angles, the 

 third joint is rather slender, distinctly longer than broad, the tollowing joints are rather 

 more slender and less elongate than they are in the allied species, the terminal joint is 

 moderately long, about twice as long as the fifth. The punctuation is moderately coarse 

 and close ; the thora.x is but little narrowed in front. We have only one e.xample.

(25) DroDiacoliis siibiilis. sp. nov. 



Robustus, elongatus, sat latus, postice acuminatus, parum nitidus, subtilissime 

 pubescens, thorace elongato, anterius angustato, angulis posterioribus elongatis, dense 

 subtiliter punctato ; elytris evidenter striatis, interstitiis discrete punctatis : antennis 

 elongatis. Long. 9{r mm.
