576 FAUNA HAWAIIENSIS 



EusiPALiA, oren. nov. 



Pectus breve; coxae intermediae minores, metasterni processus inter eas minus 

 elongatus. 



I separate under this name a form with short elytra (probably wingless), approaching 

 closely to Diestota, as exemplified by D. subcarinata. It differs therefrom not only by 

 the short breast, but also by the smaller middle coxae, the process of the metasternum 

 between them being correspondingly reduced in length. This process runs forward and 

 meets the short mesosternal process, the space at its tip being deeply foveolate. A 

 false appearance of the metasternal process being very short is caused by the deep 

 impression on its anterior part, which at first sight suggests itself as an inter\-al 

 separating the apices of the meso- and metasternal processes. 



( I ) Eusipalia bTachyptera, sp. nov. 



Nigricans, antennis fuscis, palpis pedibusque sordide testaceis ; capite thorace 

 elytrisque obsolete ruguloso-punctatis, opacis ; elytris thorace parum longioribus. 

 Long. 2^ vel 2% mm. 



Distinguished from all the species of Diestota by the elytra being slightly narrowed 

 at the shoulders and but little longer than the thorax. The sculpture of the anterior 

 parts is peculiar ; it looks as if it were a coarse sculpture nearly effaced. The antennae 

 are rather slender, but the penultimate joints are distinctly transverse. The head is 

 narrow, very dull. The thorax is a little narrower than the elytra, transverse but not 

 strongly .so, distinctly narrowed behind, very dull. Elytra flat and depressed, very 

 dull. Abdomen rather shining, but almost without punctuation. Male with a rather 

 long tooth on each side of the hind margin of the last dorsal plate and with several 

 small denticles between them. 



One specimen ; it measures scarcely 2^ mm. but the abdomen is a good deal 

 contracted. The mesosternum may be obscurely carinate, but the legs nearly hide it.

(i) Atheta olaae, sp. nov. 



Minuta, rufo-fusca, ano pedibusque flavis, capite abdomineque ante apicem nigri- 

 cantibus ; antennis brevibus crassis, prothorace leviter transverso ; subtilius crebre 

 punctulata et pubescens. Long, vix 2 mm. 



A. exilis peraffinis, statura paulo latiore, punctura et pube minus obsoletis discedit.
