Nitidulidce from the Hawaiian Islands. 137 



nitldus, tenuisslme pubescens ; protliorace transverso, 

 lateribus rotundatis, basi recte truncato, angulis pos- 

 terioribus nullo modo retrorsum spectantibus ; disco tri- 

 vel quadri-impresso ; elytris vix insequalibus, regulariter 

 seriatim punctatis ; abdomine crebve punctato. Long. 

 3| mm.; lat. 1^ mm. 



This species is closely allied to Brachypeplus im- 

 pressus, but is undoubtedly distinct, the surface of thorax 

 and elytra being much less uneven; the thorax is more 

 contracted behind, the elytra are longer in proportion to 

 their breadth, and the dorsal segments of hind body are 

 more closely punctured. I have before me four in- 

 dividuals, and if I am correct in considering them all one 

 species, it is evident that it will prove to be a variable 

 one. 



Sent by Mr. Blackburn as No. 80. 



9. Brachypeplus brevis, n. sp. Brevis, latiusculus, 

 posterius acuminatus, testaceus plus niinusve infuscatus, 

 sat nitidus, parce pubescens ; oculis parvis ; prothorace 

 lateribus rotundatis et explanatis, disco quadri-impresso, 

 minus distincte punctato ; elytris brevibus et latis, minus 

 argute seriatim punctatis, interstitiis alternis magis ele- 

 vatis ; abdomine parce punctato. Long. 3 mm. ; lat. 

 1^ mm. 



The short, broad form, the small eyes, the elevation of 

 alternate interstices of the elytra, and the slight punctua- 

 tion of the exposed dorsal segments, will render easy the 

 discrimination of this species. 



Mr. Blackburn has sent me two individuals which he 

 considers to be male and female ; I have no doubt he is 

 right in his supposition, though the marks of distinction 

 are not very conspicuous ; in one of the individuals, the 

 dorsal and ventral plates of the apical segment are a little 

 less elongate and are more truncate at the apex than in 

 the other individual, and there is exposed a very small 

 portion of a supplementary segment ; this individual is 

 probably the male. 



The specimens were foimd by sifting dead leaves at the 

 foot of a precipitous cliff, and were sent me as No. 82. 



10. Brachypeplus aper, n. sp. Latiusculus, testaceus, 

 fusco-variegatus, opacus, parce pubescens, dense punctatus, 

 inter puncta reticulatus ; prothorace lateribus rotundatis,
