9 . Head black, buccate, and very finely punctate ; palpi testaceous ; 

 mandibles and clypeus red ; frontal orbits castaneous. Antennae stout, 

 moderately attenuate apically ; blackish, often paler beneath, with the 

 central joints white at least above ; first and second joints quadrate. 

 Thora.x entirely black, shining ; metathorax scabriculo-punctate ; areola 

 somewhat semi-circular, its apex truncate ; the upper lateral areae sub- 

 confluent. Abdomen red, the first segment except its apex black, punc- 

 tate, post-petiole centrally smooth ; second segment broader than long, 

 punctate, gradually narrowed towards the base ; gastrocaeli minute, 

 oblique ; intervening space broader than central area of post-petiole ; 

 terebra black, very shortly exserted beyond the apex of the seventh seg- 

 ment. Legs stout, red ; coxae and trochanters black ; anterior femora 

 sometimes laterally fuscous, tibiae spinulose apically ; hind legs blackish, 

 base of tibiae broadly red, coxae very smooth beneath, sparsely punctate, 

 with no scopulae. Wings a little clouded ; stigma fulvous. 



$ . Head with variable pale markings, generally with the internal and 

 external orbits, two dots beneath the antennae and the mouth flavous, a 

 mark in the centre of the clypeus and the base and apex of the mandibles 

 black. ^ Antennae elongate, black, not white-banded ; the scape flavous 

 beneath. Thorax and scutellum entirely black, or with rufescent markings 

 at radix ; areola semi-lunar. Abdomen nitidulous, red or castaneous, paler 

 apically ; petiole black, more than half the width of the post-petiole, which 

 is smooth ; second segment black, apically castaneous ; gastrocaeli small, 

 oblique. Anterior legs pale red, femora laterally convex within, and tarsi 

 partly fuscous ; hind legs black, femora somewhat stout, tibiae ferrugineous 

 towards the base. Length, 8-1 1 mm. 



The points to be especially noted are, in the ? , the dark red frontal orbits, 

 the attenuate apex of the antennae, castaneous abdomen with black base, 

 the stout legs with no white markings and with the hind coxae sparsely 

 punctate and not scopuliferous ; in the 3, the castaneous abdomen with 

 black base, the sub-quadrate post-petiole, the distinct but not broad thyridii, 

 the flagellum dark fuscous below, scutellum and tegulae black, and the 

 pale line at the posterior orbits which is dilated towards the mouth. 



This species, originally considered distinct, was for long confused with 

 C. fabricator by Wesmael, with whom Bridgman agreed in considering 

 it a mere variety, in 1844. He, however, 17 years afterwards, thought it 

 sufficiently constant to claim specific rank, to which it has since been 

 raised by Thomson. As Mr. Bignell has pointed out to me, fabricator has 

 indistinctly three upper areae and fugitivus distinctly five, in the $ , which 

 may be a constant cliaracter. 



Hope found it at Netley ; Stephens took it near London, in the middle 

 of June, and in Shropshire ; Bignell has taken it at the end of August and 



1 Berthoumieu (Mon. Ich. d'Europe, 249) says the i differs from that of C. fabricator, var. ferru- 

 ^i«£i(s— presumably a mythical though comprehensive form— mainly in the flavous external orbits of 

 the eyes, " tandis que, chez /. fabricator, il n'y a qu'une lineole aux orbites des temples." But under 

 fabricator i. he says, "orbites extcrnes des yeux avec un petit trait jaune." Holmgren says of 

 /. nitilus i, " lineola vel puncto ad orbitas exteruas pallide stramineis."
