Hub. Formosa, 7 ? {Sauter). Berlin Museum. 



Tills may be said to represent in Formosa the Chinese 

 H. subopacus, Smith. In the table above, if the prothoracic 

 character is ignored, it runs to H. sisymbrii.

 Museum, 



Resembles the Australian H. blackburni, Ckll., but the 

 latter has a much broader head, mesothorax duller and 

 much less evidently punctured, &c. From all other female 

 Halicti of Formosa it is readily known by its small size, 

 dark stigma, and bandless abdomen. On account of the 

 feeble sculpture of the abdomen it cannot be the female of 

 H. luteitarsellas, Strand.

 Black, with rather abundant but thin pale hair, greyish 

 white below, slightly ochreous above ; head ordinary, clypeus
