NitidulidcB from the Hawaiian Islands. 135 



extremity, and shows a small notcli there ; the ventral 

 plate is slightly broader at the hind margin, and nearly 

 truncate. 



This species is found on the mountains in the stems of 

 banana ; Mr. Blackburn has sent me one male and three 

 females, as Nos. 18 and 19 respectively. 



1 have named this species in honour of Herr Reitter, 

 who has taken up the study of the NitiduUdcB, and pursued 

 it with much ability. His memoir on the European species 

 of Meligethes is one of the most important recent additions 

 to our knowledge of European Coleoptera. 



5. Brachypeplus injimns, n. sp. Omnium perdepressus, 

 elongatus, parallelus, subopacus, sine pubescentia, fuscus 

 vel fusco-testaceus, pedibus dilutioribus ; oculis vix ad 

 angulos posteriores capitis rectos attingentibus, hand 

 magnis ; prothorace transversim oblongo, crebre subobso- 

 lete punctate; elytris profundius striatis, interstitiis seria- 

 tim sed vix j^erspicue punctatis ; abdomine subtilissime 

 punctulato. Long. 3^—4^ mm. ; lat. 1 mm. 



The excessively-depressed form of this species distin- 

 guishes it completely from any other of the Hawaiian 

 Nitidulidce yet found. The punctuation of the head is 

 close, and is rather coarser or more distinct than that of 

 the thorax. The thorax is rather strongly transverse, is 

 truncate in front with the anterior angles rounded, the 

 sides nearly straight, the base a little rounded so that the 

 not sharply-marked hind angles are obtuse ; the surface 

 is moderately closely but rather indistinctly punctured, the 

 disc more or less flattened or depressed. The striation of 

 the elytra is very regular, and sharply defined. The ex- 

 posed dorsal segments are nearly as long as the elytra. 



In one of the sexes the apical dorsal segment is less 

 elongate at the apex than in the other sex, and leaves 

 exposed a small supplementary segment, and in this sex 

 the terminal three ventral segments are densely pubescent 

 on each side ; this is, perhaps, the male, but I feel by no 

 means sure about it. 



A pair sent by Mr. Blackburn was numbered 86 ; the 

 species occurs under the bark of trees in mountain forests.
