PACHYTERIA BORREL 179 



the exception of the brown base and sides of the head) is 

 dark steelblue with faint tinges of green and violet. 



The head is irregularly covered with strong punctures 

 which are in a great measure confluent; the punctuation 

 on the mandibles, labrum and raised margins of the cly- 

 peus is very fine, that on the cheeks sparse; the longi- 

 tudinal groove between the antennary tubers extends down 

 to the anterior margin of the clypeus (however not with- 

 out being interrupted at about the middle of the clypeus) , 

 is crossed by a well-defined narrow transverse groove at 

 the base of the clypeus, and ends behind the inter-anten- 

 nary ridge in a small smooth space. The antennae are 

 sparsely punctured , the d^*^ joint is not quite as long as 

 the two following joints taken together. 



The prothorax at base and apex depressed and constrict- 

 ed, these portions provided with transverse wrinkles; the 

 disk shows minute erect stifiBsh black hairs and is very 

 closely punctured and irregularly corrugated ; the lateral 

 tubercles are smooth ; between these tubercles and the 

 front margin of the thorax oblique wrinkles are present; 

 at the base of the disk, in front of the scutellum , a rai- 

 sed elongate triangular space may be observed , the top 

 of which is connected with the frontmargin of the disk by 

 a faint longitudinal impression. The scutellum is triangu- 

 lar, but little longer than broad at the base, with raised 

 sides and narrowly rounded tip , densely punctate and pu- 

 bescent, and with an impressed line along the middle. 



The elytra parallel , broadly and conjointly rounded at 

 the apex, densely and finely punctured, covered with a 

 minute pubescence , and provided each with two faint lon- 

 gitudinal costae, one along the middle, the other midway 

 between this and the suture. 



The legs are rather sparsely covered with irregular punc- 

 tures. 



The undersurface of the head below the mouth is trans- 

 versely wrinkled ; the prosternum especially at the sides 

 nearly impunctate , forming a distinct glossy tubercle be-
