female from Puerto Princesa differs from the allotype in having 
the front of head wider and not quite as strongly impressed on 
vertex.

Coraebus azureus sp. nov. 
Short, moderately convex, brilliant blue, elytra with trans- 
verse bands of white pubescence; beneath greenish blue, legs 
coppery, with a greenish reflection. 
Head produced in front beyond the eyes, widely and deeply 
channeled, sparsely punctate-reticulate and sparsely clothed with 
short white curved hairs, which are hardly visible on the occiput, 
except from the side. Pronotum much wider than long, nar- 
rower in front than behind ; disk convex and regularly rounded, 
with the sides narrowly depressed in front, and more widely 
at the posterior angles, the depression extending along base to 
near the middle; lateral margin regularly arcuate and finely 
crenulate ; anterior margin strongly, arcuately emarginate, with 
the median lobe strongly angulate at middle; base strongly 
bisinuate, with a broadly rounded median lobe in front of scu- 
tellum, the posterior angles broadly rounded; surface strongly 
punctate and irregularly rugose, sparsely clothed with incon- 
spicuous black hairs, becoming cinereous toward lateral margin ; 
lateral carina short and strongly arcuate. Scutellum cordate, 
transversely rugose. Elytra about equal in width to pronotum, 
slightly convex, with a deep depression along base, a similar one 
along lateral margin behind humerus, and a broad, shallow one
