19. MELAJSIOPLUS EXCELSUS, new species.. 

 (Plate XI, fig. 9.) 



Dull brownish fuscous, the under surface dull luteo-testaceous. Head 

 dark above and in a piceous band behind the eyes, but elsewhere dull 

 flavo-olivaceous, more or less clouded with plumbeous; vertex feebly 

 tumid, raised slightly above the level of the pronotmn in the male; 

 interspace between the eyes rather broader than (male) or nearly twice 

 as broad as (male) the basal antennal joint; fastigiuin plane with a 

 basal transverse impression (female) or broadly and shallowly sulcate 

 throughout (male); frontal costa broad, broader than the interspace 

 between the eyes, feebly narrowing above in the male, scarcely 

 depressed at the ocellus, and sometimes in the male slightly below it, 

 just failing to reach the clypeus, sparsely punctate; eyes moderately 

 long, anteriorly truncate, as long as the infraocular portion of the 

 genae, slightly prominent; antennae less than three-fourths (male) or 

 than two thirds (female) as long as the hind femora, fusco-ferruginous, 

 lighter at base. Prouotum gradually and slightly enlarging poste- 

 riorly, with the front margin truncate, the hind margin bluntly obtus- 

 angulate, the brownish fuscous base with a dull flavons tinge, which 

 increases on the lateral lobes except in the upper portion of the prozona, 

 which is mostly piceous, the sulci piceous, followed in the posterior sec- 

 tion by a small flavous patch ; median carina percurrent, black, sharper 

 and more elevated on the metazona than on the prozoua, the proxona 

 plano-convex with broadly rounded lateral carinae, slightly more angu- 

 late on the metazona; disk of prozoua nearly smooth and quadrate
