96 XYLOBANUS UETICILATIJS. 



ding carina between the front and posterior lateral areae 

 meets the margin near the middle of the side; the length 

 of the thorax rather greater than its width at the base. 

 Elytra with four slightly raised costae, and a double row 

 of square cells in each interval. 



There is only one female of this in the collection. 

 I think it better therefore only briefly to indicate it at 

 present. It is amply distinct from any other Sumatran or 

 Javan species I have seen. 



The specimen is from the district of Rawas (Sum. Exp.). 



6. Metriorrhynchus infuscatiis, sp. n. 



Niger; elytris rufo-brunneis , uigro-punctatis, ad apicem 

 nigris. — Long. 11 millim. 9- 



Head not rostrate , antennae widely and acutely serrate , 

 the apices of the joints only a little twisted. Thorax black , 

 the length equal to the width of the base , the sides straight 

 but narrowing to the rather distinct front angles , whence 

 they are sinuate to the apex; the seven areolae are distinct , 

 the posterior pair nearly square. Scutellum black. Elytra 

 Avith the raised lines and transverse ridges red-brown to 

 about one fourth from the apex , the bottoms of all the 

 cells and the whole apex being dull black, but the brown 

 shades ofiF imperceptibly into the black portion. 



This species almost exactly resembles Bulenides obsoletns 

 in colour as well as being very similar to Cautires excel- 

 kns and some other species. 



A single female specimen from the district of Rawas 

 (Sum. Exp.). 



7. Xijlohatms ^) reticnlatus , sp. n. 



Nigro-fumosus , elytris (apice excepto) brunneo-reticulatis, 



1) The j)rincipal difference between this genus and Meiriorr/ipic/ius appears 

 to consist in the intervals between tlie costae having a single row of cells The 

 head is not rostrate , the antennae are acutely dentate or serrate. The males 

 of some of the species assigned to it by Mr. Waterhouse have the antennae 

 with branches from the apices of the joints.
