KROTICORIS. 473 



1st joint red, base pitchy black, generally with the apex pale yellow, or 

 in the middle a pale yellow ring ; 2nd red, apical third pitchy black ; 

 3rd red, basal half pitchy black ; 4th red, base darker, apex pale 

 yellow. Eyes dark brown. Rostrum brown, tip blackish. 



Thorax. Pronotwn shagreened, and finely wrinkled transversely ; 

 in undeveloped examples piceous across the callosities. Scutellum; 

 basal angles frequently piceous ; basal portion smooth ; hinder 

 portion finely wrinkled transversely. Elytra ; Clavus brown ; claval 

 suture very narrowly pale ; Corium ; anterior margin pale yellowish- 

 white ; at the base a large whitish triangular patch, and at the apex 

 an almost square white patch, extending across the disk to the 1st 

 nerve ; the remaining portion of the disk ferruginous brown, some- 

 what paler below the apex of the clavus, and with a narrow dark- 

 brown streak next the anterior margin, which is hereon frequently 

 brown ; Cuneus black-brown ; base very narrowly red ; Membrane 

 blackish ; below the apex of the cuneus a white, somewhat triangular, 

 patch ; cell-nerves yellowish- white ; outer cell interiorly narrowly 

 margined with black ; apex black. Legs ; coxce, and fulcra yellowish- 

 white ; thighs red, with a few erect, golden-yellow hairs towards the 

 apex ; 2nd and 3rd pairs before the apex somewhat broadly brown ; 

 tibicB red, with fine, somewhat spinose, yellowish hairs ; apex piceous ; 

 knees of the 3rd pair yellowish ; tarsi brown ; 3rd joint darkest. 



Length, 2 lines. 



In undeveloped examples the anterior margin of the elytra is 

 rounded at the apex, and the markings are similar to those in the 

 developed form ; the posterior margin almost straight, and with a 

 narrow black-brown streak extending nearly from the apex to the 

 1st nerve. The 3rd 'pair of tibia are frequently blackish or brown 

 at the base. 



Length, 1-J- line. 



The description of the developed form of this insect has been 

 drawn up from a single ? taken in July of last year, on Plumstead 

 Common, by Dr. Power, who also found several undeveloped speci- 

 mens. We had also previously met with the undeveloped form at 

 the roots of very short heath at the same place ; Knighton Heath, in 

 July, and Thornmoor, York, in August, (Dale). It appears to be 

 very local.
