black crossband, the pale humeral spot small, as in typical 
D. dentipes; suture with a single row of granules; femora and 
tarsi white, tibiae prevailingly black setose-squamose. 
Byspeithes 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.

In the key given by Faust , 52 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 
stria 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 basal fascia occurs 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 Medstocerus 
makes necessary some general remarks upon the genus which, 
in consequence of an incorrect transcription, was erected as 
Mechistocerus (instead of Medstocerus) by Fauvel for Coelos- 
ternus impressus Montr., and declared by J. Faust 53 as synony- 
mous with Berosiris Pasc., the type of which is Cyamoholus marci 
Boh.; further, for Medstocerus mastersi Pasc., with linear 
femora, he has created the genus Rhadinomerus , extensively 
characterized by him in the same publication . 64 In connection 
62 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.
