Head somewhat narrowed behind the eyes, black ; temples and cheeks 

 punctate ; clypeus indistinctly separated, apically truncate ; palpi ferrugi- 

 neous ; internal and external orbits usually narrowly fiavidous ; c?also with 

 palpi, sides of clypeus and of face broadly flavidous. Antennae slender, 

 setaceous ; of $ sub-filiform, slightly compressed and white-banded cen- 

 trally, with the scape castaneous beneath ; of $ attenuated towards apex 

 with scape whitish beneath, Thorax black with usual callosities at radix, 

 and incJthe pronotum as well as sometimes two vittae on disc of meso- 

 notum and marks or lines on mesopleurae, whitish ; metathoracic areae 

 distinct, areola semi-oval and apically emarginate. Scutellum black with 

 basal carinae, and sometimes its lateral margins, whitish. Abdomen 

 castaneous-red, basal segment, and in $ the following centrally, black ; 

 post-petiole centrally aciculate ; gastrocaeli transverse, posteriorly oblique ; 

 second segment dorsally aciculate with its apical incisure deeply im- 

 pressed ; apex immaculate. Legs red ; coxae, trochanters, hind tarsi and 

 apices of hind femora and tibiae, usually black ; all the coxae closely 

 punctate, somewhat shining, $ with front ones pale-marked, $ with hind 

 ones bearing only small scopulae. Wings a little clouded ; stigma and 

 tegulae piceous ; areolet narrowed above. Length, 10-12 mm. 



The apical segments in both sexes, and the legs in the female, are 

 sometimes entirely black ; and in the variety Helleri, from the Tyrol, the 

 legs are black, with the anterior femora and tibiae laterally fiavous or 

 fulvous. 



Superficially it much resembles Coelich?ietimofi liocnemis, Thoms., with 

 which Holmgren confused it, but a glance at the coxae will sufilice to 

 distinguish them. These, in the present species, are closely punctate 

 throughout, in the latter they are glabrous, with a few isolated punctures, 

 and in the female the scopulae are much larger than in the present species. 

 The gastrocaeli, too, are shallower and oblique posteriorly, the head is 

 narrower, the areola not incomplete apically, the markings of the male are 

 more profuse, and its body more slender. 



In the present genus this species is at once known by the pale scutellar 

 carinae and red abdomen. 



I know of no British records of this species, and it is, perhaps, incor- 

 rectly included in our list, since Marshall followed Holmgren in considering 

 the latter's /. riifinus as synonymous with that of Gravenhorst. On the 

 Continent, it is found in France, Germany and Sweden, and has been bred 

 from Hemithea thyiniaria, some Geometer which Brischke calls Cidaria 

 aestivaria and from Ophiodes illunaris. The female hibernates among 

 moss.

1 As I have seen no specimens of this insect and it is not mentioned by Thomson, its position in 

 the present genus is but tentative.— Oc/ottr, 1902.
