COLEOPTERA 491 



the transverse impression on tlie disc is fairly distinct : but it is possiljle tfiat if we had 

 more material these characters miqht prove to be variable. Terminal segments as in 

 N. conferhis. We have only two specimens, both males. 



Hab. Molokai, from 4000 to over 4500 ft. (Perkins). H. S. 



(3 1 ) Nesopcplus siiutatus, sp. nov. 



Nigricans, pedibus fusco-testaceis, elytris testaceo-notatis, nitidus, leviter aeneo- 

 micans, subtile sed parum conspicue pubescens; prothorace vix transverso, antrorsum 

 angustato, angulis anterioribus vix rotundatis, lateribus ad angulos posteriores parum 

 explanatis conspicueque sinuatis, angulis posterioribus fortiter argutis, disco sat rare 

 punctate posteriusque impresso; elytris seriatim punctatis; abdomine crebre punctate. 

 Long. corp. 3 mm.; lat. corp. \\ mm. 



We have only four specimens of this species, in all of which the testaceous patch on 

 either elytron is sharply contrasted with the dark ground colour. The form of the 

 prosternal process shows it to be a true Ncsopcp/us; but the form of the prothorax, 

 though respecting the sinuation of the sides near the hind angles and other characters 

 it is only an exaggeration of what is seen in N. kocleiisis, approaches the condition of 

 certain species of AU'sopiiii/iis. 



In the male, the notch in the pygidium is shallow and broad and the tooth on either 

 side little produced (on this account the species is placed immediately before N. aie?'); 

 supplementary segment emarginate ; last ventral segment with a broad emargination. 

 Female pygidium apically depressed and somewhat broad. The single male specimen 

 shows no appreciable difference from the females in the comparative scarcity of the 

 prothoracic punctures.

(32) Nesopeplus a/er, sp. nov. 



Nigricans, prothoracis lateribus antennarumque basi pedibusque testaceis vel fusco- 

 testaceis, nitidus, sub-aeneo-micans, subtile pubescens ; prothorace vix transverso, 

 antrorsum conspicue angustato, basin versus parum angustato lateribusque vix sinuatis, 

 angulis posterioribus fere rectis, disco conspicue sed haud profunde punctate, pesterius 

 obsoletius impresso; elytris crebre confuse punctatis, seriebus fere nullis. Long, 

 corp. 3 1 mm. 



This form has several decided peculiarities. The punctuation on the elytra is 

 confused; series are visible, but their course is highly irregular. The thorax is rather 

 long in proportion to its breadth ; there is a trace of a transverse depression on the disc. 

 The male pygidium is almost truncate, the emargination being reduced to a slight 

 concave curve in the outline, the angles blunt and not produced. Last ventral segment
