 CORIZUS HYOSCYAMI. 



CoRizus Full. ? Dull., Curt. — Coreus Fall. — Lygacus Fub. — Cimex 

 Linn. 



Antcnnee inserted in a notch considerably before the eyes, half 

 the length of the insect, slightlj* clavate, pubescent, G-joiuted, 

 basal joint short stout and somewhat obovate, 2nd and 4th twice 

 iis long, slender and slightly clavate, Gth a little longer stouter 

 and suljfusiform, the 3rd and nth minute cup-shaped. 

 Labrum longer than the basal joint of the labium, verj' slender 

 and setaceous. 



Mandibles and Maxilla long and slender. 



Labium l)ent under the breast as long as the antennae, 4 -jointed, 



1st "2nd and 4th joints of equal lengtli, 3rd short and a little 



stouter than the adjoining ones. 



Head rhoniboidal , narrowed behind : eyes lateral, small and prominent • 



ocelli 2 on the crown of the head, remote. Thorax trapezifumi . 



scutellum triyonate. Abdomen ovate. Elytra, atnple, the membranous 



apes closeli/ striated lonyitudinally and crossed when at rest. Wings 



similar to Lygccus and the legs also, but the posterior are visibly the 



longest. 



Hyoscyami Linn. Faun. Suec. — Curt. Guide, Gen. 1124. 1. — Panz. 

 79. -2\.—Sam.pl. 5./. 8. 



Scarlet, pubescent and slightly rugose : antennae black, tips of 

 the 4th and a])ic;d joints ochreous : proboscis and eyes black as 

 well as a sj)ace round them ; anterior margin of thorax iuid 2 

 lunulate spots on the base black : scutellum black at the base 

 and idso a stripe on each side and a dot or 2 on the elytra, and 

 a large spot on the centre of each ; membrane bronzed brown ; 

 Avings fuscous. Abdomen with a large spot above at the apex 

 and 3 rows of spots beneath black : Legs of the same colour. 



It is obvious that tliis genus differs from Lygccus Equcstris in 

 having a rhoniboidal head, narrowed behind, and the mem- 

 branes of the hemi-elytra are furrowed and not furnished with 

 nervures. As they approach very near to each other, I have 

 given the characters of both, and shall not further illustrate 

 them in tliis work. 



Lygccus Lqucsln's anil its congeners iiaving been selected ;is 

 the types of the Fabrician genus by continental authors, the. 

 name of my genus 1121 may be altered to Heterogaster. 



Corizus Ilj/osci/ami has been found by Ca|)t. Blomer, Mr. 

 Dale ami Mr. Morris at Charmouth, Teignniouth, Dawlish 

 warren and Ravengia-^s on Thistles and Restharrow, from May 

 20th to July 1st. 1 have taken it upon the Ononis (pi. 33'J), 

 near Ventnor, the 1st of August, and on sand-hills, Braunton 

 Burrows, beginning of September. 



The Plant is Ornithogulum nutans (Drooping Star of Bclh- 

 'ehem), conununicaled by \\\ Wilbon Saunders, Em|.
