region is more or less aeneous, and there are the following 

 brassy impressions : — a large, shallow, ill-defined one on 

 the margin near the shoulders ; another similar one a 

 little behind the middle ; a third deeper one between the 

 last-mentioned and the apex ; and there are four small, 

 round impressions on the 2nd interstice ; all these 

 impressions are frosted. The apex is frosted and 

 furnished Avith yellow pubescence ; the outer or lower 

 angle has a strong tooth. The whole under side, including 

 the margin of the elj^tra, is very dark blue, and is more 

 or less dull ; the prosternal process has numerous, large, 

 strong punctures. The abdomen is very strongly and 

 rather thickly punctured, the punctures frequently 

 elongate, those in the intercoxal process particularly so ; 

 the apical segment is smooth and shining, with two or 

 three punctures only at the basal angles. 

 Length 11 lines.

Cocci nellopsis plarjiata, n. sp. 



Allied to P. solea, Klug, but without the oblique 

 brassy impressed line in front of the thorax, and having 

 a large irregular frosted, brassy impression (sometimes 

 filled with yellow tomentum) occupying the whole region 

 of the posterior angle. Thorax very dark blue [some- 

 times inclined to purple, and sometimes tinted with 

 green at the margins] , shining on the disk, sparingly 

 but very strongly punctured, scarcely constricted before 

 the anterior angles ; the medial impression narrowed 

 anteriorly, green [or golden] in the middle. Elytra very 

 dark blue, with strongly impressed dorsal striae; the 

 apex suddenly narrowed and compressed; the apical 

 impression brown and filled with yellow pubescence ; 

 each elytron has the following brassy, frosted im- 

 pressions : — one on the margin below the shoulder, 

 extending towards, but not reaching the suture; an 

 irregular, somewhat broken one about the middle, nearly 

 reaching the suture, but not the margin ; a third one 

 some distance from the apex, extending from the margin 

 to near the suture ; besides these, there are several 

 small golden spots. The under side of the insect is 

 bright brassy, tinted with pale green, strongly punctured ; 

 the sides of the prothorax are dull, pale green; the 

 reliexed margins of the elytra are beautiful green
