262 Mv. T. D. A. Cockcrell — Descriptions and 



process on liind tibise rather small, cariniform, rounded at 

 end. 



Hab. Cuernos JNIts., Negros, Philippine Islands (Baker, 

 3125). 



Closely related to Mesotridda insularis (Xi/Iocopa insularis, 

 Smith)^ from Borneo, of which only the male is known. 

 It is possible that M. cuernosensis is the hitherto unknown 

 female oP insularis, but, in view of the very different locality, 

 it is much more likely that it is a distinct species. There is 

 a superficial resemblance to the Japanese species circumvolatiSj 

 Smith. 



Mesotridiia dapitanensis, sp. n. 



? . — Length about 16 mm., anterior wing 14. 



Broad, entirely black, except that the Hagellum is dull 

 ferruginous beneath (except basally), and the hind margins 

 of the second and following abdominal segments are very 

 narrowly reddish ; pubescence all black, except a few 

 coppery-red hairs in region of mouth. Wings strongly 

 brownish, darker in apical field, reddened in marginal cell^ 

 with a greenish-golden iridescence, dilute rosy apically ; 

 head very broad ; clypens very densely punctured, with a 

 shining median ridge ; ridge between antenna obtuse, dis- 

 tinctly but not deeply grooved; third antennal joint shortei 

 than next three together ; mesothnrax smooth and shining 

 in middle ; tcgulse black. Abdomen well punctured ; first 

 t.-c. failing at lower end ; scale-like process on liiud tibiie 

 short, rounded, rather like a finger-nail. 



Hab. Dapitan, Mindanao, Philippine Is. [Baker, 3128). 



Resembles M. bakeriana, Ckll., but much smaller, with 

 the ocelli further apart, the wings paler and redder, and the 

 process on hind tibiae different.

 as follows : —

 Negros (3121).

 Iligan, Mindanao (3i24).

Xylocopa major, Maidl., ^ . — Malinao (3122). 



Xylocopa fiiliginaf a, Verez, (^ . — Dapitan (3126); ? . Iligan
