COLEOPTERA 28

sculpture at the base, the interstices between the striae quite narrow, very regular. 

 Eyes moderately large. Antennae with the basal three or four joints yellow, the rest a 

 little darker. Thorax small, straight in front, much narrowed behind, the hind angles 

 definite, not depressed, almost rectangular ; median channel definite. The striation of 

 the elvtra is wanting on the apical portion ; the third interstice is interrupted by two 

 punctures of about equal size, not minute. Two specimens. 



I have much pleasure in naming this elegant little creature after Mr Perkins. It is 

 rare to find the precinctive Hawaiian forms possessed of perfected details as is the case 

 with N. pcrkinsi\ its form recalls the perfect oudines and sculpture of some of the 

 larger, apterous Carabidae found in various continental regions ; there is a wide gap 

 between it and any other Haw^aiian species, nevertheless I think it may be placed in 

 Nesocidiinu satisfactorily. 



Hab. Kauai. Koholuamano, 4000 ft., April 1S95 (Perkins). 



(7) Ncsocidium rude, sp. no v. 



Piceum, capite rufo, antennarum articulo primo pedibusque flavis, elytris testaceis, 

 plaga magna discoidali communi picea, striato-sulcatis, sulcis indistincte punctatis. 

 Long. 2f — 3 mm. 



Plate VII. fig. 21. 



Antennae rather longer and stouter than in the allied forms. Thora.x small, 

 constricted at the base, the hind angles rectangular, median channel deep, transverse 

 anterior impression present. Elytra ovate, deeply striate, the striae broad, indistinctly 

 punctured, becoming vague behind, but still perceptible near the tip, third interstice 

 with two rather large punctures. The colour pallid, with a large dark patch, vague 

 in front, but definite behind, where it comes to a point on the suture a little before 

 the tip. Legs clear yellow. Four examples. 



This is certainly allied to N. perkinsi, though it looks almost as clumsy as that 

 species does elegant. 



Hab. Kauai. High plateau, August 1S96 (Perkins). 



(8) Nesocidiuin corlicariiiiii, sp. nov. 



Elongatum, convexiusculum, nitidum, fulvo-rufum, antennis palpis pedibusque 

 testaceis ; elytris elongatis, quadri-impressis, ad basin punctato-striatis. Long. 2f mm. ■ 



This species is concolorous, with only the legs and base of the antennae paler. 

 The eyes are rather small. The thorax is much narrowed behind, and slightly sinuate 

 just at the hind angles, which are nearly rectangular ; the median channel and the 

 anterior impression are obsolete. The elytra are elongate ovate, with si.x striae, or 

 rather series of punctures, the sutural stria is entire, the outer striae are very short, the
