COLEOPTERA 223 



(2) AlesotJn^iscits niitscicola, Blackburn. 



Anchoviciuts muscicola Blackb., Ent. Mo. Mag. xiv. p. 147, and xxi. p. 25. 



Niger, antennarum basi, palpis pedibusque testaceis, antennis extrorsum obscuriori- 

 bus ; thorace hand transverse, basin versus angustato, angulis posterioribus rectis ; elytris 

 sat protunde striatis, interstitiis planis, margine laterali rufo. Long. corp. 7 — 9 mm. 



This is very closely allied to M. vagans, but has the thorax a little differently 

 shaped, and the base of the elytra more deeply bayed, or scooped out, on each side for 

 the reception of the base of the thorax. The thorax is much sinuate behind, its hind 

 angles nearly or quite rectangular, and well defined. The elytra are broad, deeply and 

 very regularly striate, with the interstices quite flat. More than 60 examples. 



This species, like M. vagans, varies a good deal, but as no specimens of the two 

 species agree, I treat them as distinct. The thorax is always somewhat longer in 

 proportion to the width than it is in M. vagans, and the hind angles are more sharply 

 defined. Small examples have the thorax narrower at the base, and the hind angles 

 not so acute, they therefore come nearer to J/, vagans. The specimens that approach 

 nearest to the Molokai Insect are two found on the Waianae mountains, 2000 ft., in 

 February 1890, and one found on the mountains near Honolulu in August 1896. 



Hab. Oahu. Apparently common ; Honolulu mts., August 1896: Waianae mts., 

 2000 ft., February 1896; Kawaaloa, April 1893 - Kaala mts., December 1892 (Perkins).

(3) Mcsotlu-iscns prognathus, sp. nov. 



Piceus, antennis fuscescentibus, earum basi pedibusque flavis ; capite gracili, elon- 

 gato ; prothorace vix transverso, cordato, angulis posterioribus perfecte, rectis ; elytris 

 sat profunde striatis. Long. 8^ mm. 



I have seen only one specimen of this insect, and it is so close to certain extreme 

 forms of AI. muscicola that I cannot feel sure that it will prove distinct : it is, however, 

 rather more elongate in form, with a distinctly longer head and slightly longer mandibles 

 and the elytra rather less deeply striate, and I think should be distinguished till connected 

 certainly with M. muscicola. 



The unique example, for which I am indebted to Mr Koebele, is a lemale. 



Hab. Oahu (Kobele). 



(4) Mcsothriscns hmaicnsis, sp. no\". 



Piceus, antennis palpis pedibusque rufis : prothorace transverso basin versus tortiter 

 angustato et sinuato, angulis posterioribus obtusis ; elytris ovatis, sat profunde striatis. 

 Long. 7 mm.
