4 PROCEEDINGS OF THE NATIONAL, MUSEUM. vol.61. 



Ty^pe locality. — " Tangcolan, Bukidnon." 



Type and allotype.— C^it. No. 24674, U.S.N.M. 



Described from two specimens, male and female, labeled "Tang- 

 colan, Bukidnon," collected by Prof. C. F. Baker (Baker's No.'s 

 Female 14549, Male 14550). 



This beautiful insect resembles C. fulminans in form and sculpture 

 but differs from it in the color, which is of a beautiful dark violace- 

 ous blue. Doctor Kerremans in his "Monographic des Buprestides, 

 Tome III, p. 102," mentions a blue form under fulminans from Java, 

 but does not give it a separate name. As this form is so distinct it 

 seems advisable to give it a new varietal name. 



CYALITHOIDES, new genus. 



Head wide in front, broadly concave and longitudinally grooved ; 

 epistoma short and deeply, arcuately emarginate anteriorly; anten- 

 nal cavities small, rounded, the upper edge short and elevated. An- 

 tennae rather long; first joint elongate, cylindrical, about equal in 

 length to the second and third united ; second short, globular ; third 

 elongate, cylindrical and narrower than the second; fourth elongate, 

 feebly triangular, and about equal in length to the second and third 

 joints united; joints five to eleven triangular, poriferous on both 

 sides of the joints, longer than wide, gradually becoming shorter an- 

 teriorly, the last joint ovate. Eyes large, elliptical, oblique, and 

 slightly closer together on the vertex. Pronotum much wider than 

 long, rather convex without a median longitudinal groove or carina ; 

 base sinuate. Scutellum small, transverse, and touching the prono- 

 tum. Elytra subparallel, attenuate posteriorly; base feebly lobed; 

 lateral margin serrate posteriorly; surface feebly costate and with 

 discal impressions. Prosternum wide, flat, and rounded at apex; 

 anterior margin truncate. Metasternum feebly, longitudinally 

 grooved. Posterior coxae strongly dilated internally, their anterior 

 margin feebly sinuate and the posterior margin oblique. Legs rather 

 robust; anterior and middle femora fusiform, strongly dilated at 

 middle, posterior femora more cylindrical and flattened on both 

 sides; anterior tibiae feebly arcuate, middle and posterior tibiae 

 slender and straight; tarsi moderately long, the first joint of pos- 

 terior pair longer than the two following joints united, claws broadlyj 

 obsoletely lobed at base. 



Genotype. — Cyalitholdes fulgida., new species. 



This genus is closely allied to Cyalithus Thomson from Borneo. It 

 differs, however, from that genus in having the head deeply con- 

 cave in front, elytra with depressed punctured spaces^and the differ- 

 ent arrangement of the antennal joints.
