386 DYTISCID-GENUS LACCONECTUS (mOTSCH.) 



L. OCEANICUR Keg. 



2a Size smaller, 3.5—3.7 mm. 



The smallest species of tlie genus, very similar to 

 L. fidvescens but easily distinguished by the smaller size, by 

 the posteriorly more elongate and more strongly tapering shape, 

 by the still finer, posteriorly entirely obsolete stria? of elytra 

 and by some differences in colouration ; the darker shadows 

 on the disc of prothorax much more extensive ; elytra at the 

 suture and at the base narrowly, at the lateral margin 

 comparatively broadly darkened ; the subbasal lighter cross- 

 band stands out fairly distinctly against the uniformly 

 light-brown background; the reticulation especially in cf, very 

 line, the details no longer definable ; punctures entirely absent. 



Localities : Mentawi Islands and Balabac. 



Group TI. 



1. Dorsal side to the greatest extent yellowish-red or 

 brownish-red. 



L. STRIGULIFEE U. Sp. 



2. Elytra with two faint stride and numerous short rows of 

 punctures. 



In my work, "Neue Schwimmkafei"" (Ent. Blatter., xix, 

 1923, p. 36) I refer to a Lacconectus species from India, which 

 in spite of its striking and aberrant sculpture was not described 

 as a new species chiefly owing to fact that I had acc-ess only 

 to a single female specimen. I did not feel quite sure that 

 we did not have to do with a dimorphic sexual sculpture. Later 

 on, however, I received also a single male s})ecimen from the 

 same locality, which makes sure that it represents a species 

 of its own. 



Broadly oval, in shape and size nearest to L. livid us ; 

 brownish-yellow, moderately- shining ; posterior coxae slightly 

 darker ; head near the eyes darkened ; on the prothorax broader 

 "shadows in the middle and on elytra a fine sutural line and a 

 triangular-shaped marking, in the middle of the base brownish ;
