terior, the other to the posterior margin, being continued as 

 lateral marginal stripes and circumscribing the sides. Another 

 short longitudinal line dorsally in the middle reaching from 

 the transverse line to an interrupted posterior marginal line. 

 Elytra short and broad ovate, dull black, very finely coriaceous. 

 A narrow stripe at base is continued as marginal stripe to 

 apex; in the middle a transverse line confluent with marginal 

 stripe. Each elytron in basal half dorsolateral^ with a short 

 longitudinal stripe reaching from base to near the transverse 

 line, rarely joining the latter. Apical half with a sutural stripe 

 confluent with marginal stripe at apex, and a longitudinal 

 stripe, which is located more laterally than the one in basal half, 

 from the transverse line to marginal stripe. Shortly before 

 the junction this longitudinal stripe sends off a short branch. 

 Prosternum with an anterior and a posterior marginal line, 

 mesosternum with a transverse scale band, metasternum and 

 first abdominal sternite with a spot laterally. Femora with a 

 circular scale band near apex. Penis structure, Plate 3, fig. 24. 



Male, length, 12.7 millimeters (without rostrum) ; width, 5.8. 

 Female, length, 15.5 millimeters (without rostrum) ; width, 8. 



Catanduanes, Virac (Schultze). 



In the basal half of each elytron, in the male, sometimes a 

 rudimentary second longitudinal stripe is present, being in line 

 with the stripe of the apical half. This species is readily dis- 

 tinguished from related species by the peculiar sculpture of the 

 rostrum.

 Black, with greenish yellow scale stripes. Rostrum dorsally 

 in the middle with a strongly pronounced cross groove beset 

 with scales; from the cross groove extending to the front a 

 longitudinal depression beset with an elongate scale spot. Sides 

 of rostrum and head also with a scale spot. Prothorax as long 

 as broad with a more or less interrupted transverse scale stripe 

 before the middle confluent with a longitudinal stripe at the 

 lateral margins. Three other longitudinal stripes, one dorsally 

 in the middle and one toward each side, dorsolateral^, extend 

 from the transverse stripe to base. Another scale stripe, dor-
