Cutiterebra detrudator, Clk. 
Cuterebra detrudator, Clark, Addenda 1848, fig. 4; Brauer, Mono- 
graphie der Cistriden, p. 245 (1863). 
On examining the type (a female) of this species I found, 
to my intense surprise, that if my species négricincta (Ann. 
& Mag. Nat. Hist. ser. 6, vol. xv. pp. 388-390) does not 
represent the other sex of this, it is, at any rate, very 
closely allied to it. Brauer did not know the species, and 
unfortunately his translation of the original description com- 
mences with a very serious blunder, which is_ entirely 
misleading. Clark himself makes a slip, but his meaning is 
clear enough; he writes, “ Caedit (sc) maximis hujus 
generis,” which Brauer renders by ‘ Sehr grosse Art.” Asa 
matter of fact, although, as will be seen, the dimensions of 
Clark’s type correspond very closely with those of the type of 
nigricincta, owing to the somewhat narrower abdomen the 
former looks considerably smaller, and it is certainly not even 
a large specimen of the génus. A copy of Clark’s original 
description of detrudator, as well as of that of atrox, will be 
found below, and it will be seen that the former at any rate 
is too brief and inaccurate to be of any value; indeed, the 
species is quite unrecognizable from the description, but as I 
described the type of nzgricincta very fully in my former 
paper, it will be sufficient now, after giving the dimensions 
of Clark’s type, to point out in what respects it differs from 
mine. 
C. detrudator, Clk.—Type a 9. Length 192 millim.; 
width of vertex 3 millim.; width of head 84 millim.; width 
of thorax at base of wings 8} millim.; width of abdomen 
(second segment) 83 millim. ; length of wing 153 millim. 
Front nearly bare, with a somewhat shining elongate black 
area on each side, dark brown in the centre; above the dunula 
Jrontalis faintly suffused with pale golden pollen and with a 
little short pile of the same colour. Thorax with no golden 
pile on the anterior surface, and with only a small and incon- 
spicuous group of such hairs in the median line near the 
anterior margin of the dorsum, instead of a conspicuous semi- 
lunar patch ; but with a few golden hairs on either side of the 
median line in front of the scutellum. Abdomen: all the 
segments (including the fifth) metallic and bluish green 
instead of brassy green; pile clothing the third to the fifth 
segments sparser, and pale yellow instead of rich golden 
yellow ; a much broader transverse band of black pile on the 
third segment, occupying very nearly the whole of the posterior 
half of the segment ; hind margin of fourth segment also clothed 
with black pile on each side.
