Black, pronotum and elytra pale grayish brown, velvety iri- 
descent pubescent, less pronounced in the female. Male: Head 
with a suberect, slightly curved horn, which is laterally slightly 
compressed and terminates in two diverging branches. Lateral 
basal angles of the horn forming a strongly pronounced toothlike 
projection. Pronotum, the anterior lateral angles very strongly 
projecting, at the disk a short, stout horn directed forward and 
bifid at the extremity. The pronotum irregularly and conflu- 
ently punctured and densely beset with a short velvety pubes- 
cence, except the horn, which is bare toward the extremity 
above. Scutellum coarsely, irregularly punctured, with a pos- 
terior submarginal groove. Elytra irregularly punctured and 
very densely beset with velvety iridescent pubescence. Pygidium 
also densely pubescent. Metathorax beset with reddish hair. 
Abdominal segments irregularly punctured. Female: Head at 
the vertex with a very small obtuse tuberculate projection.

This species is readily distinguished by the peculiar scalelike 
velvety iridescent pubescence, somewhat similar to that of species 
of cerambycids belonging to the genus Acolesthes. 
NOTES ON SOME PHILIPPINE DYNASTID 
In my Catalogue of Philippine Coleoptera, page 173, I included 
Dipelicus deiphobus Sharp (det. C. Felsche). This species should 
€ eliminated from the Philippine list since the species in ques- 
tion is Dipelicus robustus Heller.*° 
Furthermore, Xylotrupes pubescens Waterh.” is a valid species 
and not a synonym of X. phorbanta Oliv. The last mentioned 
'$ considered by Arrow ™ as a synonym of X. gideon Linn.
