Head minutely and very sparsely punctured, vertex sparsely, rest of head 

 densely covered with white scales. Thorax hardly dilated at sides, each 

 side with a round deep pit as in the species of the genus Hydnocera Newm. 

 Apical transverse impression hardly distinct, basal well defined. Surface 

 shining with a few deep conspicuous punctures on the denuded areas. A 

 central rectangular discal spot and a smaller lateral roundish spot on each 

 side are devoid of scales. Elytra parallel, narrow, shining, coarsely and 

 sparsely punctured, punctures irregularly placed. The pattern of white 

 scales is in lines and consists of a basal transverse band with a posterior pro- 

 longation over each humerus, and a sutural stripe which widens as it pro- 

 ceeds apically and which bifurcates at about basal fourth, each ramus reach- 

 ing the lateral margin. Commencing just cephalad of each ramus and 

 crossing it are two short longitudinal stripes, each placed midway between 

 the suture and the lateral margin and extending caudad to about the middle 

 of the total length of the elytron, then striking backward and inward suddenly 

 to the suture. At the apical third there is a transverse band and from this 

 the suture is scaly to the apex. The sutural stripe widens rapidly so that 

 the entire apices are covered with scales. Apices internally obliquely trun- 

 cate, the outer angle very slightly mucronate. The under parts are blackish 

 blue laterally covered with scales. Legs testaceous, hind tibiae with sub- 

 apical notch. Length: 6.5 mm.

6. Callimerus bornensis, n. sp. 



Similar in size and form to the preceding. Black, legs and antennae 

 pale testaceous, mouth parts piceous, body more or less covered with white 

 scales. Head apparently impunctate, sparsely and evenly covered with 

 scales, these scales a little more densely placed toward the eyes. Thorax 

 hardly dilated, distinctly flattened above, very coarsely and moderately 

 closely punctured, without lateral pits. Apical transverse impression very 

 slight, basal sharply defined, distinct. A transverse, rather broad undulat- 

 ing band is free of scales. Elytra strongly and coarsely punctured, the 

 intervals between the punctures dull, alutaceous. The white scales are dis- 

 tributed as follows: a transverse narrow basal band, an undulating band 

 in the form of a W, in which the three upper points of the design are at the 

 humeri and the scutellum and the two lower are at about basal third, mid- 

 way between the suture and the lateral margin. Next on each elytron is 

 a semicircle with the convexity toward the suture, these occupying about 

 the third quarter of the length. The apices are scaly, and are internally 

 obliquely truncate, the outer angle mucronate. Under parts as in the pre- 

 ceding species. Legs testaceous, posterior knees slightly darker. Pos- 

 terior tibiae with subapical notch.
