becomes confluent with a band extending across the elytra 

 slightly behind the middle. Parallel to the last-mentioned band, 

 another at the apical fourth. Apical triangle with a large trian- 

 gular spot. Underside, a spot laterally at the prothorax, meso- 

 thorax, and metathorax. First abdominal segment with a white 

 marginal fringe, the following segments with a spot at the 

 lateral margins. 



Length, 18.6 millimeters ; width, 6.

Doliops siargaoensis sp. no v. Plate I, fig. 11. 



Dark brown, with a metallic greenish sheen and pale yellowish 

 green tomentose markings. A medial stripe on head from the 

 front to the vertex. Prothorax as long as broad, with an an- 

 terior and two posterior submarginal grooves. A narrow band 

 slightly before the middle across the disk, from one lateral mar- 

 gin to the other. Elytra basally rather densely and coarsely 

 punctured, the punctation toward the apex sparser and finer. 

 A large suboval spot at the base. Slightly before the middle a 

 combination of bands forming a triangle. At the apical third, 

 one spot near the suture and another at the lateral margin. 

 Posterior of each spot a short stripe, one subsutural and one 

 submarginal not quite reaching each other at the apical triangle. 

 Mesothorax and metathorax laterally with a large spot, also 

 first abdominal segment. The following segments, except the 

 last, each with a small spot laterally. 



Length, 13 millimeters; shoulder width, 5.

Acronia ? decimaculata sp. nov. Plate I, fig. 17. 



Shiny bluish black, with pale reddish brown tomentose spots. 

 Front irregularly punctured, with a fine medial carina and an 

 oblong bifid tomentose spot. The carina continued to the vertex, 

 but as a fine groove. First joint of antenna sparsely punctured, 

 third to eleventh joints black pubescent, the fourth joint with 

 the basal half white tomentose. Prothorax longer than broad, 

 impunctate discally, scatteredly punctured toward the lateral 

 margins. An oval tomentose spot laterally near the posterior 

 margin. Elytra sparsely and scatteredly punctured, the punc- 

 tures coarser toward the middle, but toward the apex very small. 

 The area at the middle very finely but densely black pubescent. 

 Elytra with ten tomentose spots, two of which are located at 

 the suture— a large one just behind the scutellum, the other 

 at the apical fourth— and four on each elytron, two of these
