258 PASSALID^. 



feeble, the marginal groove very fine and not dilated in front, 

 the lateral scars very small. The elytra are deejjly grooved, 

 the dorsal grooves scarcely punctured, the lateral ones very 

 minutel3^ The mentum is very strongly and closely punctured 

 at the sides, and the base has a strong rounded elevation in the 

 middle. The lateral scars of the mesosternum are large, deep 

 and opaque. The sides of the metastzrnum are verj' unevenly, 

 and in part confluently punctured, with interspersed smooth 

 areas. 



Length, 38 to 43 mm. ; breadth, 14 to 16 mm.

Although regarded by Gravely as specifically identical with 

 E. comptoni, comparison of considerable series of sj^ecimens 

 has compelled me to treat it as distinct. It is markedly 

 smaller, the lamellae of the antennal club are not quite so long, 

 and the three last are distinctly longer than the preceding one. 

 The middle tibia is less thickly fringed. The head is generally 

 rather smooth, with fewer punctures than in E. comptoni, 

 the outer processes very short, as in that species, the inner ones 

 far apart, sharply pointed and almost alike. The frontal area is 

 very short and transverse, the supraorbital ridges are fairly 

 sharp, the parietal ridge feeble. The pronotum is extremely 

 smooth, without punctures, except in the short lateral scars, 

 the median groove is well marked and the marginal groove is 

 very fine and not dilated at the sides of the front margin. 

 The sides of the mentum are strongly and closely punctured 

 and the base bears a rounded elevation in the middle. The 

 lateral scars of the mesostermim, are deep and ojiaque. The 

 sides of the mptasternum are closely and rugosely puncture<l. 



Length, 32 to 36 mm. ; breadth, 11-5 to 12-5 mm.

Specimens have been found in Rhododendron arboreum 

 trunks. 



Although it is possible that this is a small variety oi E. comp- 

 toni, as supposed by Gravely, it is certainly a well-marked 

 form with rather numerous points of difference, and I can
