DoUchoctls fasciola. 



D. striatce quoad formam similis, sed thorace pauUo angustioi-e, elj^tris 

 maculis rufis quatuor subtransversis. Piceo-fuscus ; antennis, 

 palpis, labri margiue, genubus, tibiis apice tarsisque melleo-flavis ; 

 thorace transverso medio angulato, angulis posticis subrotundatis, 

 margine lateral! late reflexo, rufo-testaceo ; elytris marginibus et 

 maculis utrinque duabus sat magnis transversim ovatis, rufis, 

 apice oblique sinuato-truncatis. 



Long. 5 millim. 



Balangoda, under bark among fungi. 



Differs from the other sirailarlj-coloured red-spotted species 

 [D. tetracolon and D. tetrastigma) in the obtuse hind angles 

 of the thorax, which are rounded at tlieir apices, and not 

 preceded bj a sinuositj. In this respect it agrees with 

 D. striata^ from which it differs in the thorax being less 

 broad, its width being not more than one third more than the 

 length. The anterior red spot of the eljtra extends from the 

 third to the eighth stria, the posterior (which is narrower) 

 from the first to the eighth. The eljtra have not the irides- 

 cent gloss that distinguishes D. striata, and the margins of 

 the thorax are much paler in colour. 



Subfamily Dhomiin^. 

 Dromius orthogonioides. 



D. brevicipiti (Bates) affinis ; differt thorace late quadrato a medio an- 

 ticeleviter rotundato-angustato, angulis anticis I'otundatis etc. Ob- 

 longus, piceo-fuscus, subnitidus, thorace marginibus pallidioribus ; 

 anteunis. partibus oris tarsisque testaceo-flavis, femoribus tibiisque 

 pallide fuscis : capile lato autice brevi et obtuso, oculis magnis ; 

 palpis sat crassis, articulo apicali oblongo, apice oblique excavato- 

 truncato ; thorace sicut in Orthogonio late quadrato, anticerotuu- 

 dato, leviter angustato, angulis anticis omnino rotundatis, posticis 

 rectis, margine laterali late explanato-reflexo, dorso subtiliter 

 transversim striate ; elytris oblongis, sat profunde striatis, apice 

 transversim leviter sinuatim truncatis, interstitiis subconvexis, 

 striis fundo hie illic subinterruptis, interstitio septimo seriatim 

 punctato. 



Long. 5g millim, 



Dikoya, under bark. 



The facies of this species, owing to its broad thorax and 

 oblong parallel-sided outline, is very unlike that of the genus 

 Dromius^ but all its essential characters are those of that genus. 

 The thickened palpi, with their truncated apices obliquely 

 sliced off and hollowed on one side, are a further development
