15. Callimerus arcufer n. sp. 



Elongate, parallel, blue, marked with lines and patches of white scales. 

 Head finely and quite densely punctured, rather different from the usual 

 condition as found in this genus. Antennae short, reaching to the posterior 

 border of the eyes, dark testaceous. Mouth parts piceous. Surface of 

 head very sparsely clothed with scales. Thorax hardly dilated, anterior 

 and posterior constrictions feeble, punctuation moderately coarse and quite 

 sparse. There are four patches of scales, one on either side of the median 

 line at both the anterior and posterior constrictions. Elytra coarsely and 

 moderately densely punctured, the punctures not in rows. On the second 

 quarter of the length there is a U of white scales common to the elytra. The 

 upper ends of the figure are connected with the side margins by fines of 

 scales. Just back of the U there is a transverse bar of scales and a second 

 bar, somewhat wider than the first is placed subapically. The under parts 

 are finely and sparsely punctured, the lateral portions scaly. The anterior 

 and middle femora are pale except for a lateral dark line, the posterior femora 

 are pale on basal half. The rest of the legs is dark. Posterior tibiae with- 

 out subapical notch. 



Length: 6 mm. 



Male. — Unknown. 



Female. — Terminal segments simple, unmodified. 



Type. — A female from Penang, Federated Malay States, C. F. Baker. 



16. Callimerus albus, n. sp. 



Elongate, parallel, black, almost entirely covered with white scales. 

 Head so densely clothed with scales that the surface is entirely concealed. 

 Eyes black, very conspicuous. Antennae and mouth parts pale testaceous. 

 Thorax somewhat dilated at sides, entirely covered with scales. Elytra 

 black, coarsely and sparsely punctured, at least where the punctures show. 

 Entirely and very densely covered with snow white scales except for four 

 small, roundish spots, two median lateral and two subapical. Tips of the 

 elytra internally obliquely truncate, the outer angle mucronate. Under parts 

 as usual, legs pale testaceous, posterior tibiae without subapical notch. 



Length: 5.5 mm. 



Male. — Terminal dorsal abdominal segment entire, somewhat dilated, 

 fringed with rather long hairs. The median part is prolonged, perhaps, a 

 slight distance beyond the lateral portions. 



Female. — Unknown. 



Type.— A male from Basilan, P. I., C. F. Baker (Baker No. 11,520). 



17. Callimerus flavus, n. sp. 



Elongate, parallel, piceous, clothed with yellowish scales. Head and 

 thorax much as in the preceding species, but the thorax is more depressed 

 along the median line. Elytra piceous, punctures coarse and moderately 

 densely placed. Surface entirely covered with scales, the scales more dense 

 in places so as to give the impression of two transverse bars, these situated
