COLEOPTERA 481 



to be placed satisfactorily in Ncsopetinus, and I therefore locate it with the aberrant 

 Nesopcpli that come nearest to Ncsopetinus. 



It varies a eood deal in colour, but the colours are more vivid than usual ; the 

 marks on the elytra consist of longitudinally placed yellow marks, of variable extent, the 

 largest immediately behind the scutellum. The abdomen may be entirely yellow, or as 

 the other extreme, blackish, slightly yellow about the margins. The thorax is distinctly 

 narrowed behind ; the angles there are definite though obtuse ; the explanation of the 

 sides is less definite than usual. The abdominal punctuation is fine and scanty. 



The male has the punctuation of thorax finer and denser than the female. The 

 structure of the pygidium is much the same as it is in Ncsopetinus vaj-iits, the male 

 having only an extremely slight emargination of the hind margin, and the angles very 

 rounded. Eight specimens.

(13) Nesopcp/us abuonnalis, sp. nov. 



Niger, supra aeneo-micans, prothorace lateribus testaceis, antennarum basi pedi- 

 busque rufo-obscuris, abdomine subtus interdum rufescente ; prothorace sat fortiter 

 punctato, bifoveolato ; elytris seriatim subtiliter punctatis. Long, fere 4, lat. i|- mm. 



A rather robust species, with short stout legs ; most like Ncsopetinus scottianus, 

 slightly larger and broader, and bearing two small depressions on the thorax in front of 

 the base in the middle. The thorax has the base nearly straight, the hind angles 

 well marked, not at all rounded but slightly obtuse ; the pubescence scanty ; the serial 

 punctures of the elytra very lightly impressed. The female pygidium is short and 

 broad, rather narrowed apically. The male has not been found. Eight specimens. 



The species is abnormal inasmuch as the prosternal process behind the coxae is 

 very short ; as its short terminal portion is strongly curved upwards, the insect is better 

 placed in Ncsopcp/us than in Ncsopetinus.

(14) Nesopeplus solitarius, sp. nov. 



% minus depressus, fusco-rufus, parce pubescens, sat nitidus, antennis pedibusque 

 testaceis ; thorace fortiter transverse, elytris angustiore, parce punctato, ante medium

Head small. Thorax considerably narrower than the elytra, but much broader 

 than long, the sides much narrowed and rounded in front, slightly narrowed behind, 

 the hind angles well marked, rectangular : the explanation of the sides narrow, but at 

 the hind angles distinctly broader and quite definite ; the punctuation is scanty and not
