206 THE ENTOMOLOGIST. 



Following Marshall's Catalogue Proholus alticola has been 

 included in the table of Amhlyteles ; for reference the genus is 

 also included in the above table, as Taschenberg, Holmgren, 

 Tischbein and Brischke are not agreed with Wesmael in sinking 

 his own genus, but it is not necessary to again refer to the 

 species here. 



EuiiYLABUS, Wesvi. 



A. Abdomen ovate or elliptic. Hind tibia) and tarsi incrassated (male). 

 Black; legs red; coxae, trochanters and apex of hind tibise and 



tarsi, black. 2. diriis, 7^ — 8 lines. 



B. Abdomen linear or oblong-fusiform. Hind tibiae and tarsi not 



incrassated. 



a. Tibiae and tarsi of hind legs entirely red or orange (male and female). 



Ring of antennae, marks on face, thorax and scutellum, yellowish ; 



legs red. - - - - 4. larvatus, 7i — 11 lines {h, t). 



h. Greater part of hind tibiae and tarsi black ; coxae and trochanters 



black ; rest of legs red. Scutellum and abdomen black (males 



and females). 



=:= 3rd segment of abdomen transverse. - 1. torvus, 5^ — 6 lines. 



=;==''- 3rd segment of abdomen quadrate. - 3. tristis, 5|- — 6^ lines. 



Our four species of Eurylahus are all rare in Britain; 

 E. torvus is the least so. Mr. Marshall gives E. larvatus as only 

 reputed British, and although in Desvignes' Museum Catalogue 

 (185G) he did not include it in his 1870 Catalogue. There are 

 two beautiful specimens in the British Museum from Desvignes' 

 collection, but of doubtful origin ; last year, however, Mr. F. D. 

 Wheeler bred three males from Stauropiis fagl, whose larvse were 

 collected in the New Forest. E. intrepidus, Wesm., given by 

 Marshall as a variety of E. larvatus, is now considered a good 

 species ; it is not British. On Wesmael's plate illustrating the 

 Ich. platyuri, E. torvus, female, E. dims, male and head magnified, 

 are figured. E. larvatus is figured by Christ. Our four species 

 have all been bred, from the following hosts : — 



1. torvus, Wesm. from Lithosia rubricollis ; Marshall. 



2. dims, Wesm. „ Eriogaster lanestris ; Sauveur, Marshall, 



Bignell, ? Wilson. Trichiura crataegi ; 

 Giraud. 



3. tristis, Gr. „ Trachea piniperda ; Brischke. Diantha3cia 



capsincola ; Brischke. 



4. larvatus, C/f )•/«?, ., Dicranura vinula; Gir. Stauropus fagi ; 



Wheeler.
