598 On Aquatic Carnivorous Coleoptera or Dijtiscidce. 



The first of the elytral striae is remote from the suture, it and the third reach 

 nearly to the base but are abbreviated a good distance from the apex, the second 

 does not reach to the base: these striae are very fine and have some distant punc- 

 tures placed on their course, the fourth (or external) stria is more broken-up than 

 the others, and is remote from the third one. In this species the extremity of the 

 posterior femora is rounded, so that both the front and hind angles are rounded. 

 The only individual I have seen is a female.

I. 5 G.— Genus LACCONECTUS. 



Coxal lines quite obliterated ; coxal lobes without incission, upper surface 

 without any sculpture except the three series of punctures ; prothorax with a fine 

 lateral margin. 



The two species are from tlie East Indian region, and are small insects, having 

 much the appearance of the Laccophili. 



904. Lacconectus basalis, n. sp. — Late ovalis, fere depressus, politus, nitidus, 

 testaceus, vertice utrinque ad oculos fusco, elytris vage infuscatis, fascia basali 

 testacea, basi summo lateribusque fuscis, vitta fusca laterali in medio a macula 

 testacea subinterrupta; elytris seriebus subtilibus punctorum iribus; corpore subtus 

 pcr-la;vigato, nitido ; antennis fere elongatis. Long. 51, lat. Ss m.m. 



This species has the appearance of a broad depressed Laccophilus. Tlie surface 

 is very smooth and shining ; the series on the elytra consist of fine very closely 

 placed punctures, between the first and second of these series there is a row of 

 distant punctures ; the points forming the third or outer series are not nearly so 

 dense as those of the other two series. The male difiers from the female only by 

 having the basal joints of the fi-ont and middle tarsi a little incrassate.

905. Lacconectus fulvescens, Motsch., M.C. — Ovalis, sat latus, nitidissimus, 

 castaneo-testaceus, antennis pedibusque testaceis ; elytris seriebus subtilissimis 

 punctorum duabus; antennis baud elongatis. Long. 4, lat. 2v m.m. 



Very closely allied to Lacconectus basalis, but much smaller, without any 

 distinct markings, and with the punctures of the elytra finer ; the outer series of 

 punctures is therefore scarcely to be detected. The male characters are much the 

 .same as in Lacconectus basali.s
