210 COPELATUS TENEBROSUS. 



2. Hydaticus litigiosus^ sp. n. 



Ovatus , convexiuscnlns; subtus nigro-ferrugiiieus , abdo- 

 niiue ad latera fulvo-notato ; auteuuis et pedibus fulvis , 

 posticis nigvo-fïiscis. Capite fulvo, in vertice et circa ocu- 

 los iiigro ; prothorace fulvo , antice et postice iu medio 

 anguste nigro ; elytris uigro-fuscis , ad latera vitta margi- 

 nali plus minus lineolis uigris divisa, ad basin vitta trans- 

 versa angusta extrorsum hamato-reflexa , paulo ultra medium 

 altera vitta transversa lata et oblique arcuata, fere ad api- 

 cem macula sublaterali, fulvo ornatis. — Long. 13 — 15 mm. 



The transverse band of the base of the elytra sometimes 

 sends out short prolongations directed backward and for- 

 ward ; the post median baud broad , irregular , more or 

 less subdivided by longitudinal black lines and points , bent 

 inward , not quite reaching the suture , sending out from 

 its hind border several linear prolongations , many of which 

 reach the subapical spot, the latter as well as the two 

 transverse bands broadly connected with the lateral band , 

 which is divided into several irregular stripes by black 

 lines and points. 



This insect differs from Hydaticus hihamatus Aubé, of 

 which it has the shape and the size , by the not sharply 

 defined bands of the elytra, and by the shape of the se- 

 cond band, which is transverse and not arched in the last 

 named species; from Goryi Aubé it differs by the much 

 shorter size , by the head not being spotted on the fore- 

 head, and by the second band of the elytra being much 

 less oblique. 



A single specimen from Moeara Laboe, captured in No- 

 vember 1877. — I possess a specimen of this species fi'om 

 .Java, whilst Mr llaffray has brought home a third speci- 

 men from that island.
