Xylocopa collaris, Lepeletier. 



£ . Sandakan, Borneo (Baker). 



This is the form which Lepeletier described from Java as 

 X. dejeanii. His collaris was based on females, doubtless of 

 more than one race, but it may be restricted to the Malayan 

 form, with Sumatra as the type locality. 



Xylocopa collaris penangensis, subsp. n. 



$ . (Type.) — Similar to the Philippine X. fuliginata, 

 Perez, in having the light hair covering first and basal two- 

 fifths of second segments of tlie abdomen, the lower margin 

 straight. Otherwise it is like X. collaris, with pale hair on 

 thorax above, except a narrow band along anterior edge of 

 scutellum. The metathorax has black hair. In the colour 

 of the hair on legs and apex of abdomen it resembles 

 X. collaris var. brijanti, Ckll., from Java, but the wings are 

 not darker than in typical collaris. The thorax dorsally is 

 very faintly greenish. The pleura has pale hair on upper 

 part and black on the lower. The insect is a little smaller 

 than typical collaris.
