108 ZONOPTERUS BOSSCHAE. 



shoulders 10 mm. — Black, with the apical half of the 

 4th antennal joint as well as the succeeding joints pale 

 orange yellow , a similarly coloured band across the middle 

 of the elytra ^) , and the three basal joints of the anterior 

 tarsi fulvous with a black point in the middle of the first 

 and second one ; moreover the lateral margins of the three 

 basal joints of the intermediate tarsi are dark brown. The 

 black portions show metallic green or blue tinges, with 

 the exception of the legs and the dark joints of the an- 

 tennae. The face and vertex of the head , the pronotum , 

 the scutellum , and the elytra (except the yellow band) 

 covered with a black velvety pubescence by which the 

 sculpture is hidden, whereas a fulvous pubescence occurs 

 on the fore-tibiae , except along their outer margin ; the 

 coxae, and the metasternum and 1st — 4th abdominal seg- 

 ment posteriorly , with a silvery pile. 



The clypeus (except the brown coloured front margin 

 which is smooth) is opaque in consequence of a very dense 

 sculpturing which is fine in the middle, coarse on the 

 sides ; a faint groove runs along the middle as a continua- 

 tion of the deep channel which divides the inter-antennary 

 ridge; moreover the clypeus is separated from the inter- 

 antennary ridge by a slightly curved groove. The base of 

 the mandibles and the cheeks are irregularly sculptured , 

 whereas a few wrinkles are present behind the eyes. The 

 scape of the antennae is strongly but rather distantly 

 punctured; the 3rd joint is slender and as long as if not 

 slightly longer than the 4th and 5th taken together. 



The sides of the prothorax are rounded, glossy and 

 impunctate. 



The elytra are gradually narrowing towards the apices 

 and show each three faint longitudinal costae. 



The under surface of the head shows irregularly confluent 

 transverse wrinkles. The prosteruum is coriaceous, its 



1) The distance from the base of the elytra to the front margin of the band 

 is equal to the broadness of the latter.
