Oxypoda semirufa. Mulsant and Key record the species from the 

 environs of Purls, Lyons, Tarbes, Cluny, Normandy, Beaujolais, the 

 Alps, &c., and Kraatz gives S. Germany as its habitat. According to 

 the first-mentioned authors, it is found at wounded places (plaies) on 

 oak trunks, and also amongst dead leaves.

DESCRIPTION OP TWO NEW SPECIES OF ERYNCOOONUS 



COTIORH YNCHINIJ . 



BY E. C. L. PEEKINS, B.A. 



The genus *Rhyncogonus was formed for the reception of two 

 species obtained in the Hawaiian Islands, but at the present time 

 eighteen species are known to me from that locality. The genus is 

 also said to occur in New Zealand. The two species here described 

 were taken by Mr. J. J. Walker, one in Oparo Islands, the other in 

 Nuka Hiva (Marquesas), and have been submitted to me by Dr. Sharp 

 for comparison with the Hawaiian species. Both are quite distinct, 

 although the species from Nuka Hiva is closely allied to some of 

 these. The other is much more remarkable. 



Ehyncogonus Walkeei, sp. nov. 



Niger, depressus,suhtiliter 'piibescens,parum nitidus. Rostrum nitidum, 



rugoso-punctatum. Oculi fortiter prominentes. Antennarum articulus se- 



cundus tertio consplcue brevior. Pronutiim fere ceqiie longum ac latum. 



Elytra ubique attperula, subseriatim punctata, subtiliter pubescentia, pseude- 



pipleuris dense velutinis. Abdomen _S subtus grossius denseque, ? subtilius 



granulato-scul pturat um, segmento apieali <? subtruncato. 



Long, (rostr. incl.J, 10"o — 12'5 mm. 



This species, in form and general appearance, is very similar to some of the 

 Hawaiian species of the genus, but it differs from all of them in sculpture, especially 

 in that of the ventral surface of the hind body. In the (J this part is densely and 

 coarsely granulated ; in the ^ the sculpture is of a similar nature, but much finer. 

 This granulation is apparently due to punctures, which are very obliquely directed. 

 The punctuation of the elytra is of a somewhat similar character. The apical ventral 

 segment of the ^ is wide at the apex and there ciliated, and sparsely clothed with 

 fine suberect hairs ; that of the $ is more acute and more finely punctured. In 

 both sexes the ridge marking off the pseudepipleural portion of the elytra is sharp 

 and well marked from base to apex, and this portion is densely pubescent. The 

 short first joint of the funiculus of the antennse distinguisiies the species from nearly 

 all tlie Hawaiian species, and those witli which it agrees in this respect are otherwise 

 totally dissimilar.
