the TeiiLbriuiiklio of Jui>(ni. 477 



Obscurely brown, more or less opaque, anteiinaj with two 

 basal joints reddish ; the head clearly punctured before the 

 frontal suture, behind the suture densely punctured, with a 

 vermicular sculpture ; the thorax without a lateral mar^rin, 

 similarly puncttired, with the vermicular sculpture more 

 general, and some of the punctures, especially those on the 

 disk, are ocellate ; the elytra are punctate-striate, with the 

 strire and punctures more or less obliterated in different indi- 

 viduals by a roujxh leather-like sculpture (not very distinctly 

 shown in the figure here), wliich at times makes the s[)ecimen3 

 opaque. The anterior femur has a somewhat acute tooth on 

 the middle of the inner edge. 



This species somewhat resembles P. clavicrus^ Mars., but 

 the femoral tooth is more acute, the tooth on the intermediate 

 tibia? of the male is wanting, and the surface-sculpture wholly 

 different, and in no specimen is the colour black. I have a 

 species a little similar to this from Siam, but it is without a 

 femoral tooth and the interspaces of the elytra are tubereulate.

Ptilonix rubripennis, AU. Mitth. SchwMZ. ent. Ges. vol. v. p. 02. 



The male of this species has a somewhat acute tooth in the 

 middle of the anterior tibia and the fourth to seventh joints 

 of the antennjB are relatively slender. The type examples 

 are rather immature, the elytra are sometimes nearly black. 

 Stenophanes mesosterna, Sols., the type of this genus, is well 

 illustrated in a figure [vide Hor. Ross. xi. 1875, p. 295, t. i. 

 fig. 8), and perhaps S. rubripennis is not specifically distinct 

 from it.

Stenophanes stri'gipenni's, Mars. 

 Helops striffipennis, Mars. Ann. Fr. 1870, p. 138. 



This species differs from the above in having the tooth of 

 the anterior tibia less acute ; but the best distinguishing 

 structural character is, however, in the relative shortness of the 

 fourth to seventh joints of the antennse. This species is 

 always quite black.
