Dolichoctis quadriplagiatus. 



Dolickoctis quadriplagiatus, Motschiilsky, Bull. Mosc. 1861, p. 106 

 ( Cyrtopteriis) ; Chaudoir, Ann. Soc. Ent. Belg. xii. p. 245. 



Colpodes maryinicollis, Walker, Ann. & Mag. Nat. Hist. 1859, iii. 

 p. 51. 



In many places, on fungi. 



The specific name marginicolUs was used for a Colpodes in 

 Chaudoir's ' Monograph,' published the same year as Walker's 

 unrecognizable description. 



Dolichoctis vitticolUs, 



D. quadriplagiato multo minor, piceo-fuscus ; thorace late ovato, 

 lateribus late explanatis minime reflexis, angulis postieis late 

 rotundatis, pallida testaceo, vittis duabus piceo-fuscis ; elytris mar- 

 ginibus maculisque elongatis utrinque duabus (iuterdum in vittam 

 conjunctis) ; palpis, antennis et pedibus pallida testaceis. 



Long. 3|-5 miUim. 



Dikoya ; refuse in damp jungle. 



The thorax is relatively broader and much more regularly 

 ovate than in B. quadriplagiatus^ the hind angles being entirely 

 rounded off, the sides evenly rounded, with broadly explanated 

 and very slightly upturned margins. The head is smaller 

 and the eyes less prominent ; the elytra are relatively short 

 and ovate in outline ; the lateral pale border occupies the two 

 marginal interstices. 



Dolichoctis gonioderus. 



Augustus, fusco-piceus, nitidus ; elytris nigro-piceis ; antennis, parti- 

 bus oris, thoracis margine pedibusque paUide testaceis, femoribus 

 medio tibiisque fuscescentibus, elytris margine laterali et utrinque 

 maculis elongatis tribus (prima antero-discoidali secuuda et 

 tertia subapicalibus) pallide testaceis ; thorace angusto, bexagono, 

 marginibus lateralibus anguste explanatis, valde reflexis, ante 

 medium utrinque valde angulatis, angulis anticis prominulis, pos- 

 tieis obtusis, margine basali i^rope angulum obliquato. 



Long. 4 millim. 



Kitugalle, in refuse. One example only. 



Allied to D. angulicolUs (Chaud.), but the spots of the 

 elytra different in number and position, being three on each 

 elytron — one elongate, not reaching the base, and ending 

 nearly in a point about the middle ; the two others shorter, 

 side by side near the apex, the outer spot a little anterior to 

 the inner one.
