DESCRIPTION OF A NEW SPECIES 



OF THE 



RHYNCHOPHOROUS GENUS CRYPTODERMÂ 



(Oxyrrliyiiclins olim). 



BY 



Dr. H. J. VETH. 



Crijptoderma Knapperti n. sp. 



Elongatns, coiivexus, crnsta argillacea indutiis, supra et 

 infra colore lactis, thorace elytrisque quatuor fasciis nigris 

 longitudinalibus ornatis, fascia interna in prima tertia elytrorum 

 parte valde excisa, antennae rostri apicem excedentes, pedibus 

 argillaceis. 



Length from the anterior margin of the thorax to the apex 

 of the elytra 7 — 11 mm. : width at the shoulders 2V2— ^4-/5 mm. 



This species differs in pattern considerably from all the 

 known species of the genus. It has a yellowish white or 

 creamy color when the insect is in good condition ; in most 

 of the individuals before me it is, however, of a more or 

 less dirty pale brown. Four longitudinal black bands run 

 from the anterior margin of the prothorax to the apex of 

 the elytra or end a little before the apex ; two of these bands 

 are situated on the backside (one on each side of the middle- 

 line), the two others are lateral and hardly visible from above. 

 The two first named bands become narrower anteriorly and 

 posteriorly and show, at the end of the basal third of the 

 elytra, at their outer side, a curvature, and just behind this,
