black crossband, the pale humeral spot small, as in typical 
D. dentipes; suture with a single row of granules; femora and 
tarsi white, tibize prevailingly black setose-squamose. 
Dyspeithes dentipes Kirsch. subsp. punctatostriatus ‘subsp. nov. 
A specie typica differt prothorace in dimidia parte anteriore 
vitta marginali fuliginosa, elytris macula humerali, oculo duplo 
majore, rotundata, ochracea excepta, transverse ochraceo- et 
fuliginoso-marmoratis, striis distincte punctatis, spatio secundo 
quartoque reliquis convexioribus. 
Long. 7 mm., lat. 4.

In the key given by Faust,°*? D. dentipes Kirsch. may be 
differentiated by having only two black scale tufts on the an- 
terior margin of prothorax, whereas in the other species there 
is also a transverse discal row of such tufts; but the type speci- . 
men.is much worn, and the remnants of scale tufts can be 
discerned placed as in D. dentipes Kirsch. The Philippine 
subspecies agrees in this respect with both, but differs by the 
strize being distinctly (in dentipes hardly) punctate within, the 
second and fourth intervals being more convex than the others, 
and by a yellowish patch on the shoulder, twice as broad as 
the eye. 
In both forms, dentipes and subsp. punctatostriatus, a narrow, 
black basa] fascia oceurs on the base of the third to the seventh 
intervals, which borders the pale humeral patch behind, this 
patch in the typical species being much smaller. 
GENUS MECISTOCERUS FAUVEL AND ALLIED GENERA 
The description of new Philippine species of Mecistocerus 
makes necessary some general remarks upon the genus which, 
in consequence of an incorrect transcription, was erected as 
Mechistocerus (instead of Mecistocerus) by Fauvel for Coelos- 
ternus impressus Montr., and declared by J. Faust ** as synony- 
mous with Berosiris Pasc., the type of which is Cyamobolus marci 
Boh.; further, for Mecistocerus mastersi Pasc., with linear 
femora, he has created the genus Rhadinomerus, extensively 
characterized by him in the same publication.* In connection 
® Ann. Mus. Genova 40 (1899) 55. On this occasion the same author 
mentions a D. nycteroides Faust—a misspelling, as nechyroides Faust is 
the correct name.
