9. Callimerus luzonicus, n. sp. 



Elongate, head and thorax dark testaceous, the latter usually distinctly 

 greenish, elytra varying from piceous to rufotestaceous. Head shining, 

 almost impunctate, with a few white scales near the eyes. Thorax not 

 strongly dilated but with distinct anterior and posterior constrictions. 

 Lateral depressions distinct, circular. Entire surface devoid of scales, 

 though distinctly pubescent. Elytra long, parallel, piceous with the ex- 

 treme base rufous to rufotestaceous with the lateral margins and tips pice- 

 ous, evenly covered with white scales. Punctures moderate in size, dis- 

 tinctly in rows, the rows spaced more or less evenly from the suture to the 

 side margin. Tips internally obliquely truncate, the outer angle with 

 mucro, the inner broadly rounded. Under parts as usual with the lateral 

 parts densely scaly. Legs pale with greenish tinge. Posterior tibiae with 

 subapical notch. 



Length: 7-8.5 mm. 



Male. — Terminal dorsal abdominal very broad and deeply cut out so 

 that the lateral horns are quite slender. These horns are bent under and 

 are widened into hooked chisel-like blades. The center portion of the seg- 

 ment is slightly produced and broadly rounded. 



Female. — Terminal segments simple, unmodified. 



Type. — A male from Mt. Makiling, Luzon, P. I., C. F. Baker (Baker No. 

 11,546). Paratypes: males and females, Mt. Makiling, C. F. Baker (Baker 

 Nos. 1655, 1656, 11,546). 



10. Callimerus fuscitarsus, n. sp. 



Elongate, slightly tapering behind. Dark testaceous, side margins of 

 the thorax and flanks of the elytra with the tips dark. Head finely, almost 

 invisibly punctured; smooth and shining, with a few whitish scales near 

 the eyes. Thorax slightly dilated at sides, anterior and posterior constric- 

 tions distinct, lateral depressions round and shallow. Low down on the 

 sides there are a few scales. Surface shining, almost impunctate. Elytra 

 with punctures in rows, surface more or less densely covered with scales, 

 with longer hairs intermingled. Tips of the elytra truncate, the truncature 

 hardly oblique, the outer angles with mucro. Under parts shining, very 

 sparsely punctured, lateral portions of thorax and abdomen densely covered 

 with scales. Legs pale, femora with greenish tinge, posterior tarsi and tips 

 of tibiae dark fuscous. Posterior tibiae with subapical notch. 



Length: 6-7.5 mm. 



Male. — Terminal dorsal abdominal segment broad and bilobed, the lobes 

 semicircular. 



Female. — Terminal segments simple, unmodified. 



Type. — A male from Singapore, Federated Malay States, C. F. Baker 

 (Baker No. 11,540). Paratypes: A male from Penang and two females 

 from Singapore (Baker No. 11,535). 



11. Callimerus lateralis, n. sp. 



Similar in form and appearance to C luwnicus. Head smooth, shining, 

 sparsely and moderately finely punctured. Thorax somewhat dilated, an-
