Head red with the face flavou.s, the occiput and vertex black. Antennae 

 with the scape rufescent above and flavous beneath ; the flagelhim dull 

 red, its two basal joints discally black, and the apical ones mainly nigre- 

 scent. Thorax dull red, or in ^ mainly black; prothoracic marks, scutel- 

 lar region, a longitudinal metathoracic vitta, with pleurae mainly, black. 

 Abdomen rufescent with fifth to seventh 9 segments discally and laterally 

 infuscate. Legs red with the anterior flavidous; hind tibiae apically 

 piceous, their tarsi flavous with metatarsus dull red. Wings slightly 

 clouded with the tegulae and stigma testaceous. Length, 12-15 ™it1' 



It is said to have the conformation of Labrorhychus ienuicornis, but 

 Gravenhorst says the antennae are a little stouter. Records appear very 

 scanty and Schm. mentions it only from central Europe, though it is in- 

 cluded as French by Gaulle. Bridgman introduced it as British (Trans. 

 Ent. Soc. 1884, p. 425), since Bignell had sent him "this pretty species" 

 bred from Tacniocampa gDthica ; but no one else has met with it and I 

 possess but a single female, which I place here with some doubt ; this 

 was bred from a chrysalis of Epunda viminalis, found at Doncaster, of 

 which six were kindly sent me on 8th August, iqoo, and this alone 

 emerged on the 3rd of the following May; the thorax is but sparsely red- 

 marked.

Head posteriorly explanate ; cheeks and the rufescent temples nitidu- 

 lous, face apically strongly constricted with mandibles partly rufescent 

 and clypeus centrally acuminate. Antennae about as long as body and 

 rufescent beneath. Thorax black with prothoracic marks, the rugosely 

 punctate mesonotum laterally, and sometimes scutellum, rufescent ; notauli 

 wanting ; metathorax rugulose. Legs red with anterior coxae and tro- 

 chanters black, as are whole of hind legs except the red metatarsus. 

 Wings with stigma piceous, tegulae red, and the parallel nervure subcon- 

 tinuous with median. Length, 12-13 mm. 



Forster described it from southern France and Brauns from Hungary, 

 where it was bred trom Zygaena laeta by Mocsary, to which Schm. adds 

 Z. carniolica. I possess a couple of males raised by J>arrett from Psyche 

 villosclla and a female bred frum a sallow-feeding Toiirix on 24th July, 

 iqof), at Studland in Dorset by Haines, upon the strength of which I 

 consider this species to be British.
