3. Melanoclerus parvus, n. sp. 



Form parallel, robust; head small; with eyes, not wider than the pro- 

 thorax; black. Head finely and sparsely punctured, frons slightly im- 

 pressed either side of the median line, sparsely pubescent. Antennae very 

 short, the segments densely and finely punctured, ninth strongly trans- 

 verse, tenth equal in width to ninth but somewhat longer, eleventh cultri- 

 form, as wide as the tenth and as long as the ninth and tenth together. 

 Mouth-parts very dark piceous. Thorax longer than wide, finely mar- 

 gined at base, very densely and finely punctured, pubescence short and 

 dense, with some longer hairs intermingled. Scutellum small, rounded be- 

 hind. Elytra with rows of coarse punctures at base, punctures becoming 

 obsolete just before middle. Apical half of the elytra densely and finely 

 punctured. Pubescence short, depressed and gray, with longer erect black 

 hairs. Under parts densely punctured and sparsely pubescent. Legs 

 short, posterior femora not reaching posterior border of second abdominal 

 segment, dark piceous, slightly paler at joints. Length: 4.5 mm. 



Type: A female from Sandakan, North Borneo, C. F. Baker. 



4. Callimerus princeps, n. sp. 



Elongate, parallel, black; legs, antennae and mouth parts pale, more or 

 less covered with glossy white scales. Head finely and very minutely punc- 

 tured, entirely covered with scales except for the vertex and a narrow line 

 running down onto the frons. Thorax longer than wide, dilated at the 

 middle, broadly and shallowly impressed at the apex, narrowly and more 

 deeply at the base. A triangular median spot, and the lateral portions are 

 free from scales. Elytra parallel, black, deeply and coarsely punctured 

 except along the suture at the median third of the length. Surface of the 

 elytra between the punctures dull, alutaceous. There are seven denuded 

 areas, one subbasal on each elytron, one median lateral on each elytron and 

 one median central, common to the two elytra, and one subapical on each. 

 The apices of the elytra are internally obliquely truncate, the outer angle 

 only, mucronate. Under parts black, laterally densely covered with white 

 scales. Legs pale testaceous, the femora showing traces of green pigment. 

 Posterior tibiae with subapical notch. The entire surface of the beetle has, 

 in addition to the scales, a vestiture of long, erect hairs, rather sparsely 

 placed. Length: 7 mm. 



Male. — Terminal dorsal abdominal segment dilated and bifurcate. 

 Each ramus extends outward and downward, becoming gradually widened 

 to the tip, which is sharply truncate. The tips of the rami are turned under 

 toward the median line. Between the rami there is a small triangular pro- 

 jection. 



Female . — Unknown . 



Type, — A male from Basilan, P. I., C. F. Baker (Baker No. 11 ,534). 



5. Callimerus intricatus, n. sp. 



Elongate, parallel, slender. Bluish; antennae, mouth parts and legs tes- 

 taceous; vestiture of white scales unevenly distributed over the body.
