397. Coelambus funiatus, n. sp. — Ovalis, angustulus, testaceus, abdomine pectoreque 

 nigricantibus, prothorace basi elytrisque infuscatis, bis dense sequaliter subtiliter 

 punctatis, stria punctorum irapressa distincta ; coxis posterioribus fere crebre 

 punctatis. Long. 3l, lat. 2 tn.m. 



The only individual I have seen is a female, it is extremely closely allied to 

 Hydroporus lutescens (No. 39S), but is a good deal smaller, the punctures on the 

 coxa are not quite so dose, and the tarsi are much smaller tlian in the individual 

 described of that species.

398. Hydroporus lutescens, Lee, M.C. — Ovalis, angustulus, elongatus, testaceus, 

 abdomine pectoreque nigricantibus, prothorace basi elytrisque infuscatis, his dense 

 sequaliter subtiliter punctatis, stria punctorum impressa distincta ; coxis posteriori- 

 bus crebre punctatis. Long. 4, lat. 2s m.m. 



This species is smaller than H. nubilus (No. 403), and more finely and closely 

 punctured : I am not sure as to the sex of the only individual I have seen, the claws 

 of the front tarsi being equal though the tarsi are rather broad ; the shape of the 

 front and middle tarsi is however quite different from what it is in either sex of 

 Hydroporus nubilus. 



The determination of the name is not certainly cori'ect, as I have seen no typical 

 specimen of this species.

399. Hydroporus patruelis, Lee, M.C. — Ovalis, sat elongatus, sine pubescentia, 

 sat nitidus, testaceus, pectore abdomineque nigris, elytris apicem versus vage infus- 

 catis, prothorace basi obscuriore ; elytris minus fortiter, basi minus crebre sub- 

 insequaliter, apice fere dense punctatis ; coxis posterioribus crebre punctatis. Long 

 4, lat. 2^ m.m. 



Mas, tarsis anterioribus fortiter dilatatis, unguiculo interno crassiore. 



Very closely allied to Hydroporus nubilus (No. 403), but less elongate with the 

 male front tarsi rather broader and shorter, and the colour and sculpture not quite 

 similar. 



According to Crotch, H, discoideus, Lee. (Proc. Ac. Phil. 1855. p. 299), is a male 

 of this species.
