.312 Mr. 'W D. A. Cockeiell — Descrijitions and 



abdominal segment practically as in tahaonis ; the margins 

 of tlie scutellar incision are curved, producing a — *— >, not 

 practically straight as in takaonis. 



Crocisa amata, sp. n. 



Length 9 to 13 mm. 



Black with very brilliant but not shining turquoise-blue 

 markings : runs in my table in ' Entomologist/ Aug. 1910, 

 to G. decora, Smith, to which it is very closely allied. Cora- 

 ]iared with a Singapore example of decora, it differs as 

 follows : markings a little lighter, with a faint greenish 

 shade, occasionally almost white ; basal band of first abdo- 

 minal segment very thick in middle, projecting from beneath 

 scutellum, but sublaterally interrupted or much narrowed 

 (in decora thick and even, with a linear median interruption) ; 

 sublateral discal spots of thorax smaller. 



Huh. Formosa (Saiiter). Berlin Museum. 



I have before me 37 males and 27 females ; the type is a 

 male from Takao. The localities and dates are Takao, 

 Oct. 11, 19, 30, Nov. 2, Dec. 5, 15, 1907; Kanshi, June 8, 

 1908; Fuhosho, July 1909 ; Kanshirei, June 8, 1908. 



This is a blue-marked species, with the hind femora of the 

 male bearing a large, sharp, thorn-like tooth, in all respects 

 very close to the mainland C. decora. I should have thought 

 it a variety of decora, had I received only a single specimen, 

 but the very long series holds its characters well, slight as 

 they are. In the ' Entomologist,' 1910, p. 219, I expressed 

 some fear that 1 might not have correctly identified decora ; 

 but since then Mr. Meade- \^'aldo has examined Smith's type 

 (a female from N. China) for me, and returns to me one of 

 the specimens from Sitif^apore I had considered decora, 

 assuring me that it is a true exponent of the species. 

 Mr. ]\Ieade-Waldo adds : '' decora is certainly marked with 

 strong, dark blue (not the pallid wash of Transcaspian 

 specimens of the genus Crocisa) ; the bands on the abdomen, 

 viewed from above, almost meet (rather more so than in 

 Singapore specimen) ; the mesothoracic spots are far from 

 the prothoracic band, a line drawn through the extreme 

 anterior edge of the tegulse would just pass through the 

 hinder edge of the mesothoracic spots.'' 



Crocisa kanshireana, sp. n. 



Length about 12 to 14 mm. 



Black with cobalt-blue markings, which are not at all 

 shining; scutellum . — "— ^-like, with a blue apical patch.
