On Aquatic Carnivorous Coleoptera or Dytiscide, 431 
I have seen only males of this species, which is extremely closely allied to D,suavis 
but israther larger, and is readily distinguished by the denser and finer sculpture of 
the ventral segments. 
I have from Persia a specimen which is either a variety of this species, or else a 
closely allied species. I have seen no specimen from Armenia, (the locality of 
Aubé’s specimen) and am not quite sure whether this be really his species. 
Asiatic Turkey, (Tarsus). 259. 
482, Deronectes indicus, n. sp.—(¢) Ovalis, subtilissime pubescens, subtus niger, 
capite thorace, antennis pedibusque rufis, thorace antice et postice nigricante, elytris 
testaceis signaturis magnis confluentibus fuscis ; thorace lateribus obliquis, haud 
curvatis, angulis posterioribus nullo modo rotundatis, fere rectis; elytris apicem 
versus fortiter denticulatis, corpore dense subtilissime punctato. Long. 4%, lat. 
2¢ m.m. 
The male has the second and third joints of the front tarsi short, and much 
dilated, and the claws of these feet very unequal; the hind one being much the 
longer. I have seen only one individual. 
Northern India, (Coll. Bonvouloir). 287. 
483. Deronectes abyssinicus, n. sp.—Ovalis, convexus, fere sine pubescentia, vix 
nitidus, niger, capite in medio prothorace versus latera et in medio vage rufis, elytris 
testaceis, lineis elongatis approximatis, fere integris, nigris; prothoracis lateribus 
obliquis, angulis posterioribus fere rectis haud rotundatis ; corpore dense sub- 
tilissime punctulato, prothorace punctis majoribus conspicuis, pedibus rufescentibus 
posterioribus piceis. Long. 42, lat. 22 m.m. 
In the male the elytra are rather strongly denticulate near the extremity, the 
front and middle tarsi are but little broader than in the female, but the hinder 
claw of the front ones is distinctly lengthened. 
In this species the outline of the thorax and elytra is very continuous ; when the 
wing-case is taken off, it is seen that the portion forming the humeral angle projects 
forward very much.

484, Hydroporus carinatus, Aubé, M.C.—Ovalis, opacus, fere sine pubescentia, 
ferrugineus, thorace elytrisque nigricantibus, illo lateribus, his basi et signaturis 
variabilibus testaceis : thorace angulis posterioribus omnino rotundatis, elytris 
costa longitudinali fortiter elevata ; corpore dense subtilissime reticulato-punctato, 
elytris fere impunctatis, obsoletissme rugosis ; thorace punctis majoribus obsoletis. 
Long. 43, lat. 27 m.m.
