CHILOCORUS. 183 



species with 7 abdominal segments in the male. Also seeing that 

 almost all the chilocori shew a tendency to pubescence on the 

 thorax, I have added Platynaspis from the Scymnides, and have 

 brought together all the species in which the presternum is pro- 

 duced so as to conceal the men turn, and in which also the 

 femora are received into deep cavities. These genera were quite 

 unlike the Scymnides, but are closely allied to Cryptognatha etc. 



Chilocorus. 



Leach. Edin. Ency. ix. p. 116 (typ. cacti). 



Spread over the whole world. The sides of the thorax are 

 nearly always pubescent, and in C. Midas the humeral angles of 

 the elytra also. 



A. Thorax black, elytra unicolorous black, or metallic, or 

 spotted with red. 



Chilocorus tristis. 



Chilocorus tristis, Fold. Mem. Ret. (Sav. Etr.) ii. 452. 95. 



Muls. Spec. p. 452. 1. 



Chilocorus rubidus, Hope, Zool. Misc. p. 31 (1831) T. 



Muls. Spec. p. 453. 



Japan, N". China, Mongolia, Nepaul. Mulsant also cites 

 "New Holland," but probably in error. Punctuation sparse and 

 faint, form compi'essed. Thorax with the sides straight, pubescent ; 

 elytra with deep scattered punctures on the margin. 



Chilocorus rufitarsis. 



Chilocorus rufitarsis, Mots. Et. Ent. n. p. 50. 



Chilocorus monachus, Muls. Op. vn. p. 147 (T). 



Closely allied to C. tristis by the shape of the thorax, but 

 hemispherical, not compressed. Head, body and legs reddish 

 orange, disc of elytra with a common ill defined red spot varying 

 in extent. L. 2^ lin. China, Shanghai (Deyrolle, Guerin, 

 Chevrolat). Motschulsky's description is not exact, but will 

 suit this species very well. 



Chilocorus infemalis. 



Chilocorus infemalis, Muls. Op. in. p. 61 ... (1853) T. 



Chilocorus bijugus, Muls. Op. ill. p. 61 ... (1853) T. 



"Very convex, compressed, black, shining thorax with the sides 

 straight, punctuation fine, very sparse, elytra each with 2 orange 

 dots, placed so as to form a transverse common series a little 

 befoi'e the middle; ventral segments orange red. L. 2 lin. N. 

 India (Deyrolle). 



Mulsant has described this insect twice, but no doubt can exist 

 that both descriptions refer to the same species, which is allied to 

 C. tristis.
