Lepidonotus sp. ? 



A nearly perfect Lepidonotus 12 mm. long was at first referred to 

 L. carinulatus Grube. a species that has been recorded from the Red 

 Sea and the Philippine Islands by Grube, from Japan by v. Marenzeller 

 and more recently from Ceylon by Willey. There exists a close 

 resemblance, especially in the character of the elytra between this 

 specimen and Grube's description but serious discrepancies arise with 

 Marenzeller's and even more with Willey 's descriptions. The neuro- 

 podial seta> are of the typical Lepidonotus type with no trace of a 

 true subapical spur, but the last pair of toothed plates is greatly de- 

 veloped and superficially somewhat resembles a spur, the remaining 

 ones being reduced in number and much reduced in size or even 

 obsolete. On the whole they resemble the corresponding setse of 

 L. caioris but are more slender. 



On most of the elytra the horny bosses take the form of subcircular 

 bases rising into more or less compressed keels, many of which are 

 more or less irregular and spinous but which as a rule are smooth and 

 lack the sculpturing so evident on typical L. ccdoris. Anterior elytra, 

 however, show traces of this sculpturing on the more conical papillae. 

 The marginal fringe is very long and extensive. The prostomium has 

 the typical Lepidonotus form quite unlike Willey 's figure of L. carinu- 

 latus. Their color is pale brown with a light spot over the point of 

 attachment. 



On the whole it seems best to consider this specimen provisionally 

 as a variation of L. caioris.
