4i6 FAUNA HAWAIIENSIS 



(i) Saciiirn angusticolle, sp. nov. 



Oblongum, convexum, sat angustum, nitidum, pubescentia pallida, subtiliter nee 

 densius punctatum, tnterstitiis laevis ; pronoto rufo, elytris nigris apicibus piceo-ferru- 

 gineis, pedibus flavo-ferrugineis, antennis flavis clava obscuriore ; pronoto angusto, sat 

 eloneato, antrorsum ovaliter rotundato, margine vix reflexa, basi baud fortiter sinuata, 

 angulis fere rectis, linea basali baud profunda. Long, f — i-^ mm. 



This species is distinguished by its small size ; by the fine punctuation and smooth 

 shining interstices ; by the black elytra with no lighter colour except at the extreme 

 apex ; and by the pronotum, which is red, paler in front, narrow, rather long, distinctly 

 narrowed in front, so that the outline forms an elliptic curve, with the margin hardly 

 reflexed. 



Eight specimens. One specimen, from which the lower length measurement is 

 taken, is conspicuously smaller than all the others. 



Hab. Hawaiian Is. Two specimens recorded from Oahu, one being from Kaala 

 mts. 2500 ft. ; the other six have no quite certain particulars, but are almost certainly 

 from Oahu (Perkins). 



Anisomeristes Matthews. 



Anisoineristes Matthews, Ent. Mo. Mag. xxii. 1886, p. 225 ; Mon. p. 108. 

 This genus is separated from Sericoderus chiefly by the antennae having eleven 

 joints, while those of Scricode7'us are ten-jointed. 



(i) Anisomeristes basalis. Sharp. 



Sericodenis basa/is Sharp, Tr. Dublin Soc. in. 1885, p. 127. 



Anisomeristes basa/is Matthews, Mon. p. 112. 



This is a somewhat broad form with conspicuous pubescence. It is of yellowish 

 colour, with the basal parts of the elytra dark ; in the specimens found by Blackburn 

 this portion is black, but in two specimens (both unfortunately in bad preservation) 

 received from Mr Perkins, it is less dark, in one being only somewhat infuscated. The 

 terminal dorsal segments of the body are dark. 



Hab. Oahu. From the salt marshes in the plains (Blackburn). No particulars 

 as to locality (Perkins). 



Sericoderus Stephens.
