3. Philhydrus Wollastoni, n. sp. 



P. subovalis, sat convexus, nitidus,piceo-niger, prothoracis elytrorum- 

 que limbo dilutiore, capite maculis duabus parvis ante oculos, 

 paljiis autennanimque basi testaceis, pedibus piceo-rufis ; capite 

 prothoraceque crebre subtiliter, elytris parcius obsoletiusque 

 punctatis, his seriebus tribus punctorum majorum impressis. 



Long. 2| lin. 



Inhabits the Cape-Yerde archipelago, having been found 

 by Messrs. Wollaston and Gray in the islands of S. Antonio, 

 S. Vicente, S. lago, and Brava — in the first of which it was 

 met with likewise by Dr. H. Dohrn. 



Var. j3 panic brevier et magis convexus, colore dilutiore, palpis 

 paulo brevioribus et crassioribus. 



Found in S. Antonio, this very slightly different form 

 being the one which is distinctive of that island. 



Nearly as large as the northern P. melanocephalus, but 

 darker and more uniform in colour, with its elytra sparingly 

 and much more indistinctly punctured, and with the claws 

 of its tarsi much smaller and scarcely differing in struc- 

 ture in the two sexes, — in which last respect it resembles 

 P. ovalis, Th., and marginellus, Fab,, and differs decidedly 

 from P. poUtuSj Kiist., and maritimus, Th. 



4. Philhydrus hesperidum, n. sp. 



P. oblongo-ovalis, leviter convexus, nitidus, capite nigro, maculis 

 duabus parvis ante oculos, antenuarum basi palpisque testaceis, 

 his apice summo subinfuscato ; prothorace disco piceo-nigro, 

 marginibus testaceis ; elytris fusco-testaceis, parce obsoleteque 

 punctatis, seriebus tribus punctorum majorum impressis ; pedibus 

 piceis, tarsis dilutioribus. 



Long. l|-2 lin. 



Inhabits the Cape -Verde archipelago, having been detected 

 by Messrs. Wollaston and Gray in S. Antonio, S. Vicente, 

 S. lago, and Brava. 



Closely allied in form and appearance to the European P. 

 marginellus, but not quite so large as that species, and at once 

 distinguishable from it by its very sparingly and obsoletely 

 punctured elytra. It pretty closely resembles P. Wollas- 

 toni', but its smaller size and more oblong form, as well as 

 several differences in the details of its colour and punctation, 

 will suffice to distinguish it.
