NEW SPECIES OF BOARMIIN^ FROM FORMOSA. 343 



narrow, sharply pointed, extending nearly half a millimetre beyond 

 last dorsal, not at all notched at sides : under side of last ventral 

 striated. 



Hah. Formosa (no special locality given). Easily known 

 by the peculiar clypeus. The apical structures of the abdomen 

 are entirely of the type of C. brevis, Ev., and C. rufocaudata, 

 Sm., except that the last dorsal is much more elongate. Com- 

 pared with C. siamensis, Ckll., the abdomen of G. rhinosus is much 

 more densely punctured, and the clypeus is entirely different. 



A second paper will deal with the genus Nomia as repre- 

 sented in Formosa.
