EROTICORIS. 473 



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

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

 yellow. Ei/es dark brown. Rostrum brown, tip blackish. 



Thorax. — Pronofum shagreened, and finely wrinkled transversely ; 

 in undeveloj)ed 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 ; Coriiim ; 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

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 tihice are frequently blackish or brown 

 at the base. 



Length, 1\ 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.
