7iew WooiJ-horing Beetles. 3S3 



Some specimens lately received from Mr. Green from 

 Ceylon as attacking AUiizzia moluccana and Hevca brasili- 

 ensis were found, 1 understand, iu the Botanical (iardens, 

 and therefore their country of origin must remain in doubt. 

 Out of teu specimens found by Mr, Green iu a dead branch 

 oi Albizzia muliiccano, one proved to be E. stwspinosKS (S), 

 Motsch.. and the remainder Xyleltorus asperutas, Hldf., au 

 insect of similar sculpture antl general form. It seems 

 therefore higlily probable that these may be the sexes of the 

 same species. 



Cnestus, gen. nov. 



Caput rotundatum, oMectuin ; oculi traiisversi ; antennrc scapus 

 longus, funiculus 4-articulatus, articulis 2-4 transversis, lati- 

 tudine crescentibus ; clava magna, ovalis, oblique apice truncata. 

 Trotborax quam elytris longior, ultra caput productus ct 

 tuberculis multismaguisornatus. ycutcllum parvum. Elytrorum 

 disco pallido. Abdomen normalis. Coxic ant ice approximatae ; 

 femora pallida ; tibite fusca;, antice extus serratse, a basi aa- 

 trorsum dilatatae et oblique truncatae ; tarsi elougati. 



The prothorax is continued anteriorly downwards and 

 then upwards beyond the bead, aud is edged with a series of 

 large tubercles. The elytra are almost transparent, except 

 at the edges and along the suture, where tliey are very dark 

 iu colour. 



That the immaturity of the elytra is only a])parent seems 

 to be proved by tbe appearance of the other parts of the 

 insect. 



I have been unable to dissect the mouth-parts owing to 

 scarcity of material. 



Cnestus maynus, sp. n. 



Oblougo-ovalis, nitidus, nigor, elytris (marginibus exccptis) pal- 

 lidis ; tborace autice granulato-asperato et iiistructo tuberculis 

 octo, postice profuude puuctato ; elytris subtilissime puuctato- 

 sti'iatis ; striis juxta suturalibus lortiter punctatis ; corpore toto 

 sparsim hirto. 



Long. '6 mm. 



Hub. ? Ceylon. 



This insect was taken by Mr. Ernest Green from living 

 branches of Albizzia moluccana. The prothorax is longer 

 than the elytra by the length of the overhanging apical 

 portion, strongly asperate aud tuberculate in front, and 

 posteriorly covered with large punctures somewhat widely 

 separated, the intervening spaces being very shiny; there is
