deep black, each slightly tipped with ferruginous : elytra striated, 

 without any punctures. (Length 4 lin. ; breadth l^ lin.) 



I have only a single specimen of this remarkable insect ; it 

 is in Mr. Davis's cabinet, but he does not know its locality. 



Natural Order. ? 



Genus. — Leptura. Linnceus. 



From the examination of a number of living specimens of 

 Leptura ^-fasciata and apicalis, I have no hesitation in 

 saying, that the latter is merely a variety of the former ; 

 I have found them with five, four, three, two, one, and 

 sometimes only half a joint of the antennae of the pale colour 

 which characterises the species : these varieties occur equally 

 in both sexes, and copulation takes place as commonly between 

 individuals of opposite varieties as between two having antennae 

 of the same colour. Between Toxotus meridianus and c/tr?/- 

 sogaster, I have likewise found every possible variety ; in 

 these instances the specific character differs only in the redness 

 of the abdominal segments. In Herefordshire, where these 

 insects are exceedingly abundant, so great is the variety, that 

 I have never detected a copulation between two individuals 

 that were similar in this respect. The names apicalis and 

 chrysogaster should therefore be discontinued. 



Class. — Hemiptera. 



Natural Order. — Cimicites, ined. 



Genus — Acanthosoma. Curtis. 



Acan. picta. Flavo-viridis ; proalis fascia recurva coccinea 

 ornxtis. 



Antennae green, more or less tinged with red : head yellow green : 

 prothorax of the same colour, with its posterior margin at each 

 angle tinged with red : scutellum of mesothorax green : upper 

 abdominal segments sooty black, with green margins : ultimate 

 and penultimate entirely green : interior half of the costal margin 

 of fore-wings yellow-green, below which is a broad, bright, red 

 band, superiorly concave, inferiorly convex : exterior portion of 

 the wing hyaline, with a black transverse fascia and spot : hind 

 wings, towards the abdomen, clouded with black, towards their 

 apex hyaline : legs green, occasionally tinged with red. (Length 4| ; 

 breadth 9^ lin.)
