Ditoneces propinquus. 



(Plate VII. fig. 11.) 



Piceo-fuscus, pubescens, depressus, parallelus ; thorace nitido, 

 sordide flavo, disco infuseato ; elytris sordide flavis, crebre sat for- 

 titer punctato-striatis, interstitiis augustissimis. J . Long. 3 1 lin. 



Hah. China {J. C. Bowring, Esq.). 



Very near the preceding, but of a sordid yellow colour above ; the 

 thorax a little narrowed in front and completely rounded anteriorly, 

 the disk dusky, moderately impressed on each side. The antennae 

 are nearly as in I), rufescens, but the joints are a little shorter. 

 Elytra strongly punctate-striate ; the interstices extremely narrow, 

 the alternate ones a little more distinct and more elevated, especially 

 the fourth and sixth, 



Ditoneces sobrinus. 



(Plate VIII. fig. 2.) 



Nigro-fuscus, parallelus, pubescens ; thorace flavo-rufo ; elytris 

 flavo-rufis, striatis, striis obsoletius punctatis, interstitiis angustis, 

 fere aequalibus. c? . Long. 2| lin. 



Hab. Burmah (J. C. Bowring, Esq.). 



Differs from the three preceding species in having the punctua- 

 tion of the striae of the elytra less strong and more obscure, the in- 

 terstices being a little less narrow, and all equal except the eighth, 

 which is a little more elevated. The antennae have the branches to 

 the sixth and seventh joints about as long as the joints. The usual 

 short channel in the middle at the base of the thorax is scarcely 

 noticeable.

Hah. Ceylon {Dr. Thivaites). 



This species is densely pubescent above. The punctures in the 

 striae of the elytra are rather large and close, but are much obscured 

 by the pubescence ; the interstices are extremely narrow and all 

 equal. The male has very long branches to the antennal joints, at 

 least three or four times the length of the joints. The female has 

 the antennae very strongly dentate. 



The type specimens to which Mr. Walker gave the above-men- 

 tioned names clearly belong to one species ; his revocans is a small
