244 LOMAPTERA CASTANEA. 



but differs however from this species by its smaller size, 

 by the want of the round nodosity on the middle of the 

 head , by the almost impuuctate abdomen , and by the 

 sculpture of the pygidium Avhich is transversely striate all 

 over and not punctured on the inferior portion. From Lomap- 

 tera timoriensis Wall, it differs , besides by its smaller 

 size, by its different shape, the lateral margins of the 

 elytra being parallel and not attenuated towards the apex, 

 and from Lomaptera tristis Rits. , besides by its smaller 

 size and parallel shape , by its less dense sculpture , the 

 elytra being moreover punctate-striate , etc. 



Length (from the anterior margin of the pronotum 

 down to the apex of the elytra) not quite 15 mm.; breadth 

 at the shoulders 8 mm. 



Glossy black ; the elytra , a narrow transverse and sub- 

 divided band on the base of the pygidium , and a spot on 

 the middle of the second, tliird and fourth ventral seg- 

 ments of a chestnut color. 



The head sparingly covered with punctures of different 

 size; the longitudinal impressions of the lobes of the cly- 

 peus furnished moreover with longitudinal striae. 



The pronotum sparingly covered with almost impercep- 

 tible punctures on the middle of the disk, on the median 

 lobe and along the basal margin ; towards the sides of the 

 disk the punctures become deep and large. The sides of 

 the pronotum, especially towards and on the anterior 

 angles, rugose by confluent deep punctures forming short 

 striae ; the apex of the median lobe rounded. The scu- 

 tellum of an elongate triangular shape. 



The elytra at the base distinctly broader than the base 

 of the prothorax ; their lateral margins parallel , narrowly 

 notched and pointed at the suture. The shoulders and 

 apical tubercles smooth , the disk irregularly punctate- 

 striate; the punctures tend however to disappear almost 

 entirely towards the suture on the basal half and towards 

 the apical tubercle. Moreover there is a row of punctures 

 on the elytra along the suture and the median thoracical
