with ten lines of close, moderately strong punctures, the intervals 

 extremely narrow, the alternate ones scarcely more distinct. 



The male is rather narrow, the thorax broadest in front, slightly 

 constricted at the middle. 



The female is broader and more parallel, and the thorax is quadrate. 



Var. A single female example differs from the typical form in 

 having the thorax, scutellum, and legs yellow ; the thorax is slightly 

 transverse and a little constricted at the middle. The elytra have 

 the second, fourth, and sixth interstices distinctly costiform. This 

 may prove to be a distinct species.

Broader than the preceding, parallel, depressed, of a rusty yellow 

 above. Antennae very broad. Thorax somewhat reflexed at the 

 sides, with seven areolets ; the four anterior areolets and the sides 

 thickly and roughly punctured. Elytra with the four costae well 

 marked ; the punctures in the rows are very strong ; the fine line 

 which divides the rows is very fine, but distinct. 



Metriorrhynchus dilutus. 



(Plate XIV. fig. 6.) 



Parallelus, opacus, dilute flavus ; antennis fuscis, artieulo basali 

 flavo ; thorace marginibus crebre punctatis ; elytris quadricostatis, 

 interstitiis biseriatim crebre punctatis (punctis elongatis), dimidio 

 apicali fusco ; abdomine fusco, ano flavo. Long. 3| lin. 



Mab. My sol (Wallace). 



Thorax quadrate, slightly transverse, the anterior areolets not 

 completely divided anteriorly ; these and the lateral margins thickly 

 punctured. Elytra with the four costae distinct, the intervals with 

 two rows of rather elongate punctures, with an extremely fine line 

 dividing the rows. The outer side of the tibiae and the tarsi are 

 somewhat dusky.
