Callimerus bakeri, n. sp. 



Form, size and superficial appearance much as in C. luzonicus Chpn. 

 Frontal region including clypeus rather densely punctured, occiput and 

 vertex smooth and shining. Eyes margined in front with white scales, 

 which are continued in a band across the punctured portion of the front. 

 Thorax urn-shaped, the basal transverse impression bordered behind by a 

 sharply raised ridge, anterior impression broad and shallow, with numerous 

 very fine transverse striae, especially toward the middle. Lateral dilations 

 moderate, lateral foveae broad, circular and shallow. Punctures fine and 

 sparse. Scutellum truncate behind. Elytra long, lateral margins almost 

 parallel, apices obliquely truncate, the outer angle of the truncature with a 

 rather conspicuous mucro. Punctures rather fine, arranged in longitudinal 

 rows, the rows becoming closer together as the lateral margin is approached 

 but without the conspicuous crowding of rows 4-6 as in C. lateralis Chpn. 

 Scales yellowish white, evenly distributed over the elytral surface. The 

 flanks of the elytra are slightly darker than the disc. Under parts heavily 

 scaled along the sides, abdominal sternites moderately closely punctured. 



Male: Terminal dorsal with broad median triangular lobe which is sub- 

 acute at apex. Laterally, the segment is prolonged into a thin, flat ramus 

 on each side, which ends in an upwardly directed thorn-like triangular 

 process. The lobes of the penis sheath end in short, outwardly-directed 

 hooks. Fifth and sixth ventrals transverse, nearly straight. 



Female: Fifth ventral with a very broad and shallow emargination, the 

 width of the emargination about equal to one-half the width of the sclerite. 



Length: 6.5 mm (c?)— 8 mm. (9). 



Type: A male from Butuan, Mindanao (C. F. Baker 17541), paratypes 

 as follows: a female from Surigao, Mindanao (C. F. Baker 14726), a female 

 from Iligan, Mindanao (C. F. Baker 12736) and 4 males and 3 females from 

 Surigao, Mindanao (C. F. Baker), 3 females from Butuan, Mindanao.
