Abilorneii in iiialc with pui'ple and groeii tints ; b isal band 

 of fii\st abdominal segment narrow, slender, often interrupted 

 in middle; apical band of first segment also rather slender, 

 interrupted in middle line by a space about equal to distance 

 from notch in scutellum to one of its lateral points ; bands 

 of first segment not united at sides ; the other l)ands, four 

 in number, are transverse, interrupted about as widely as 

 that on apex of first segment ; median stripe of me^othorax 

 going back about to middle ; discal spots small, isolated ; 

 raesothorax with much black hair ; pleura crossed by a blue 

 band, narrowed in middle. Wings very dark ; apex of male 

 abdomen with three low lobes (in C. ainata truncate, with a 

 tooth-bke pencil of hair on each side) ; hind femora of male 

 unarmed ; hind tibise with a patch of blue hair at base ; 

 hair of basitarsi black, in female with a fair amount of blue, 

 in male with the blue reduced to a few hairs, often onlv on 

 anterior tai'si. 



Hah. Kanshirei, Formosa, June 8, 1908 {Saufer). 6 (? , 

 2 ? , in Berlin Museum. 



A very closely related Crocisa from Foochow, China 

 {Caldioell), difiers by the much duller, grei/ish-hhie of the 

 abdominal markings ; the W-like scutellum, wdthout an 

 apical blue patch ; the broader median mesothoracic band ; 

 the apical band of first abdominal segment very narrowly or 

 not interrupted, and joined at sides by a longitudinal band 

 to the basal ; and the abundant light hair on the tarsi. 



In Friese's table of Oriental and Australian Ct'ocisa (Ann. 

 Mus. Nat. Hung. 1909) this runs in both sexes straight to 

 C. emarginata , but it is certainly not the emaryinata of 

 Lepeletier, which has shining blue markings. In my tab'c 

 in 'Entomologist,'' Aug. 1910, it runs nearest to C. decora, 

 to which it is not closely allied. 



It is seen from the above that Formosa contains three 

 species of Crocisa, all of different groups. All are close to 

 Chinese species, but nevertheless distinct. 



AxN'DROGYNELLA, geu. UOV. 



Like Megachile, but female with 13-jointed antennae, and 

 ventral surface of abdomen smooth and bare, without any 

 trace of a scopa. Junction of third and fourth antenna! 

 joitits in female very oblique. Male with short flattened 

 anterior coxal spines or lamellae ; anterior tarsi somewhat 

 modified. Tvpe AndrogyneUa detersa {Megachile detersa, 

 Ckll.). 



The species was described from a single female. Mr. R.
