CocciNELLA, Linn. 

 A number of species of very convex form constitute this genus ; they 

 vary, as do those oi Hippodamia, in the extent of the black markings, but 

 may be separated thus : — 

 A. Elytra red, immaculate. White margin of thorax with three 



branches sangumea, Linn. 



x\A. Elytra reddish or yellowish with black markings, 

 b. Thorax with anterior margin white. 



Elytra with three black transverse fasciae, sometimes reduced 



or partially divided, .22 in iri/asciata, Linn. 



Elytra with a common scutellar, and each with four other 

 spots, black, the two anterior smaller, .2()-.^o.g-}iotata, Hbst. 

 bb. Thorax with anterior angles only white. 



c. Elytra strongly punctulate, shining ; thorax with anterior 

 angles triangularly white. Elytra each with a triangular 

 subapical black spot and a common black sub-basal 



fascia tridentate anteriorly, .19 in iriaispis, Kby. 



cc. Elytra alutaceous, obsoletely punctulate. Thorax with a 

 quadrate white spot on the anterior angles above. 



Anterior thoracic angles only narrowly white beneath. 

 Sub-basal spots of elytra usually united into a com- 

 mon fascia, .28-30 in transversoguttata, Fabr. 



Anterior thoracic angles as broadly white beneath as 



above. Elytra without sub-basal band, usually 



with an oblique medial fascia, a scutellar spot and 



asubapicalspoton each, .28-.30 'm....inonticola, Muls. 



Of the above species, C. tricuspis is unknown to me in nature. 



Figures are given of C. sanguinea, Fig. 42 ; C. tri/asciata, Fig. 43 ; C. 



g-Jiotata, Fig. 44, and its larva. Fig. 45, and pupa, Fig. 36 ; C. irans- 



versoguttata, Fig. 46 ; and C. moftticola, Fig. 47.
