the Coccinellidae of Japan. 27 



Coccinella ainu, sp. n. 



Nigra, supra convexa, nitida; elytris runs, 12-mgro-nunctatis, 



parurn dense punctulatis. 

 L. 5-5| mill. 



In colour very similar to C. 11-punctata, Linn., but more 

 broadly oval, and the elytra have a humeral spot. The head 

 black, with two yellow spots touching the interior edge of the 

 eye, punctulate ; the thorax, punctuation clearer than that 

 of the head, anterior angles broadly pale ; the pale patches 

 are sometimes joined by a pale anterior narrow margin ; the 

 elytra, on either side of the scutellum is a pale triangular 

 spot, and behind it a large black sutural spot common to 

 both wing-cases; in the dorsal region, but quite clear of 

 the suture, are four more black spots (sometimes the poste- 

 rior pair are smaller than the anterior pair), on the lateral 

 area are three smaller spots on either side, the basal or 

 humeral spot is nearer to the intermediate spot than the inter- 

 mediate spot is to the apical one. The surfaces of the elytra 

 are more distinctly punctulate than in either C. 11-punctata, 

 L., or G. 7 -punctata, L. Beyond the pale thoracic margin 

 noticed above I have not seen any variation of importance. 



I lab. Sapporo and Mororan, in August 1880. Found 

 abundantly in company with C. Crotchi in the flowers of 

 " immortelles " growing in a dry river-bed. 



Coccinella ronina, sp. n. 



Oblongo-ovata, nigra, nitida ; capite in medio flavo-maculato ; 



thorace utrinque pallide marginato : elvtris 4-maculatis, maculis 



flavis vel rufis. 

 L. 4-4| mill. 



Oblong-ovate, black, shining ; the head black, with a pale 

 median spot between the eyes, finely punctulate ; the thorax 

 punctulate like the head, with a pale lateral band or border 

 rather broad and of equal width throughout ; the scutellum 

 very small and punctulate ; the elytra also punctulate, each 

 wing-case with two pale or red spots placed longitudinally in 

 a line with each other near the centres of the wing-cases ; a 

 point between the spots would indicate the centre of eacli 

 elytron ; the epipleural rim is very narrow, especially near the 

 humeral angle; the ventral segments are laterally pale or 

 reddish. 



Hab. Oyama in Sagami and Junsai in Yezo.
