and a new genus of Cossonides. 11 



in P. dehile, it being in the male just about the middle of 

 the rostrum, in the female a little behind it. 



For this species I am also indebted to Mr. R. Lawson, 

 who recently received it from his brother, with the 

 P. Wollastonianum. 



Pentarthrum parvicorne, n. sp. Brevius, subdepressum, 

 sat nitidum, ferrugineum, fortiter punctatum ; prothorace 

 elongato, antrorsum fortiter angustato, pone marginem 

 anteriorem leviter constricto, lateribus versus basin evi- 

 denter rotundatis et angustatis, crebrius fortiter punctato; 

 elytris sat fortiter striato-punctatis, interstitiis punctulatis. 

 Long. 2 mm. 



In this species the eyes are prominent and quite near 

 the neck ; the 2nd joint of the funiculus is not longer 

 than the following ones, the 3rd tarsal joint is distinctly 

 larger than the 2nd and bilobed, though the lobes are not 

 large ; the sculpture of the elytra takes the form of series 

 of rather coarse punctures which are somewhat depressed, 

 so that the elytra might almost be said to be striate, the 

 interstices appear a little rough, and on examination with 

 a very gr ^d glass are seen to bear excessively short indis- 

 tinct s'^ ce ; all the portion of the rostiaun in front of 

 the <.ntennal insertion is broader than the posterior por- 

 tio- , and the antennae are inserted about the middle. 

 T' e rostrum is thick especially in the male, and in that 

 sex it is opaque ; in the female it is rather longer, more 

 slender and more shining, and is nearly as long as the 

 thorax behind the constriction.

 by Mr. B. Lawson. 



Pentarthrum remotum, n. sp. Brevius, robustulum, 

 subdepressum, sat nitidum rufo-piceum, antennis clava 

 elongata, nigra ; prothorace lateribus rotundatis, antror- 

 smn angustato, pone marginem anteriorem depresso, 

 crebrius fortiter pimctato, dorso subdepresso, medio ad 

 basin subfoveolato ; elytris prothorace paulo latioribus, 

 fortiter punctato striatis. Long. 2 — 2^ mm. 



This little species is easily recognizable by the club of 

 the antennfB, which is elongate, so that it quite equals in 

 length all the rest of the funiculus, and it is also darker 

 in colour than the other joints, and entirely covered 

 with fine pubescence. In each sex the rostrum is rather
