posterior wings are wholly )3ale brownisli-yellow, excepting the dark brown ptero- 

 stigma. 



Hah. : as in the type form (Hudson, No. 1-1+). I have examined 

 two examples. 



Var. OBLITERATUS, var. nov. 



In this form both whitish and dark markings have practically disappeared from 

 the wings (the dark pterostigma always excepted), which are iiearly uniformly 

 brownish-yellow (or vice versa), the posterior paler. But on the anterior there is 

 usually a faint trace of the pale markings (if examined in a good light), and the 

 excised apical uiargin is narrowly darker with paler interspaces. 



Hah. : as in the tj-pe form (Hudson, No. 14). I have examined 

 four examples. Mr. Hudson also indicates one example from Mt. 

 Arthur, Nelson, 3600 feet, January, 1889 : this I have not seen. In 

 uniformity of coloration this form might be likened to a very diminu- 

 tive S. citrinus. 



I see no reason to doubt that all the examples before me belong 

 to the same species. Mr. Hudson is also of that opinion. The forms 

 above described represent extreme and intermediate conditions, which 

 in all probability could be coiniected in a long series ; but it seemed 

 advisable to apply varietal names. 



In the falcate wings, and the character of the markings in the 

 type form, there is some resemblance to the North Indian Osmylus 

 Langii, McLach., and allied species of Osmylus from the same region.

CRABRO CAVIFRONS, Thom., C. PLANIFRONS, Tdom., C. CHRYSOS- 

 T031US, St. Faeg., and C. SAVXDERSI, m. 



BY E. C. L. PERKINS, B.A. 



In this Magazine (1899, p. 110) I recorded Grahro planifrons, 

 Thoms., as occurring in this country. In this I was in error, for the 

 examples in question do not belong to that species, which, through the 

 kindness of the Eev. F. D. Morice, I have since had the opportunity 

 of examining. Mr. Morice obtained males of C. planifrons in Switzer- 

 land, and also sent me a female of the same which had been determined 

 by Kohl. Although the specimens which I referred to G. planifrons 

 are almost certainly identical with the Grahro sexcinctiis of Wesmael, 

 they apparently require a new name, because the G. sexcinctus of 

 Smith is another species, in fact, a rather uncommon variety of the 

 species we know as G. ce.plialotes, such as I have occasionally met with 

 myself. I therefore propose that the species which is new to this 

 country be called Grahro Saundersi, in honour of Mr. Edward Saun-
