Fuscous brown; head with three indistinct longitudinal yellowish streaks 

 above ; thorax tricarinated, the lateral carina slightly curved, edged with 

 greenish-yellow within, and dusky without ; elytra fuscous, with a darker 

 streak at the shoulder, and a bright greenish-yellow one on the costa 

 extending to about its middle ; wings yellowish at the base, and fuscous at 

 the apex ; posterior femora greenish-brown, with their under surface bright 

 blood-red, the base within with a black streak, a cloud of the same on both 

 sides towards the apex, and a ring near the knees; tibiae bright yellow, with 

 a black ring at the base and apex, and a fainter one towards the base; 

 spines bluish-black. 



Variable in colour, some examples being of a brilliant fleshy or purple hue 

 when alive, and in some the latter colour is retained when dried. 



Although not an uncommon insect in this country, it would appear, 

 from the silence of Charpentier, Zettersted, and other continental 



JSp. 3. cserulescens. Grisea, eJytris fasciis duabus et apicem versus maculis 

 obscurioribus, alis viridi-carulescentibus, fascia apici hyalino propriore,

Griseous ; elytra with two transverse fasciae, one occupying the base, and 

 some spots towards the apex obscure ; wnngs greenish-blue at the base, the 

 apex clear, and towards the middle a curved black fascia, in both sexes. 



This insect is also introduced by Stewart as indigenous, but evidently without 

 authority. 



B. Thorax with three elevated lines. 



a. With the two outer thoracic lines nearly straight. 



JSp. 4. grossa. Thorace subtricarinato, carinis lateralihus obsoletis ; virescens, 

 elytris margine exteriore antice, in utroque sexu, Jlavo, femoribus posticis 

 subius sanguineis geniculis nigris. (Long. corp. 10—12 lin.) 



Gry. grossus. Linne. — Berkenhout (!) — Lo. grossa. Steph. Catal. 301, No. 3319, 

 note. 



Thorax obscurely tricarinated, the lateral ridges obscure ; greenish ; elytra 

 with the costa, or outer margin, anteriorly yellow in both sexes ; hinder 

 femora beneath blood-red, the knees black or dusky. 



Berkenhout gives this as British, but I presume improperly, as I have never 

 seen an indigenous example.
