spots, some larger, some smaller, of a whitish or ivory colour ; and 

 there is another transverse series of similar marks behind the 

 middle. The legs and antennae are yellow, the club of the latter 

 being a little infuscate ; the tarsi are short. 



Grey mouth. A single individual, sent by Mr. Helms. 



Adolopus. 



1833. A. helmsi, u.s. (Sharp; Trans. Ent. Soc. Loud., 1884, 

 p. 478.) Piceus, limbo dilutiore, elytrorum apice irregulariter pallido, 

 pedibus runs ; tarsis, palpis, antennisque testaceis, harum clava 

 fusca ; corpore supra crebre punctate, et in elytris seriatim fortiter 

 punctatis, seriebus ad basin desinentibus. 



Long., 3mm. ; lat., fere 2mm. 



The punctuation on the head, thorax, and basal portions of the 

 elytra is close and rather coarse ; on the head it becomes finer in 

 front, so that on the epistome it is excessively fine, the surface there 

 being opaque and alutaceous ; the series of punctures on the elytra 

 are coarse behind, and at the sides none of them extend to the base, 

 the outer ones stopping short rather abruptly at about one-fifth of 

 the length ; those nearer the suture extend very nearly to the base, 

 becoming, however, very fine in front, and the one or two next the 

 suture hardly extend so far forwards as the two or three outside 

 them ; the sutural series becomes deepened behind into an hnpunc- 

 tate stria. 



Greymouth. Helms. 



Adolopus altulus (No. 158) is extremely similar to A. helmsi, but 

 is a trifle smaller, has the serial punctures of the elytra behind 

 much coarser, the series near the suture very much shorter, and the 

 margins explanate behind ; the punctuation of the thorax is also 

 finer and more scanty. 



Phelerosus. 



Nov. gen. 

 (Sharp ; Trans. Ent. Soc. Lond., 1884, p. 480.) 



Antennae 7-articulatse ; palpi maxillares parum elongati, articulis 

 longitudine subaequalibus ; prothorace elytris angustiore basi quam 

 apice haud latiore ; prosternum ante coxas omnium brevissimurn. 

 Femora posteriora glabra. Generi Berosi proximus, sed femora 

 posteriora tantum ad summum basin pubescentia discedit. 



Although so close to the widely-distributed genus Berosus, I 

 think this insect had better be isolated therefrom, the hind femora 

 being pubescent only where they touch the coxas ; the side-pieces of 

 the prosternum are less prolonged inwardly than they are in Berosus, 

 and the prothorax is slightly impressed on the middle. 



1834. P. pallidipennis, n.s. (Sharp; Trans. Ent. Soc. Lond., 

 1884, p. 480.) Capite thoraceque seneis, densissime punctatis, hujus 

 margins anteriore et lateribus cumque elytris pallide testaceis ; subtus
