376 MANDIBULATA. — COLEOPTERA. 



Genus CCCCXV. — Coccinella Auctorum. 



Antennae rather short, clavate, the capitulum compressed, obconic, with the 

 apical joint largest and subtruncate. Palpi maxillary, long, very robust, 

 the terminal joint very large, securiform: head small: thorax transverse, 

 broadest at the base, but narrower near the elytra, the hinder margin 

 rounded, with the angles acute: elytra ample, slightly margined: hody 

 subhemispheric, sometimes a little oblong-ovate, convex : legs short : tarsi 

 obscurely quadriarticulate. 



From Chilocorus the present genus differs not only by having 

 distinct hinder angles to the thorax, which last is broadest behind, 

 but by having the elytra scarcely margined, the maxillary palpi 

 distinctly elongate and robust, with the terminal joint more or less 

 securiform : the antennae elongate, with the capitulum compressed 

 obconic-truncate, and the body but slightly gibbous or hemispheric : 

 the species are generally extremely prone to vary; and both in their 

 larvae and imago states seem destined to keep the numerous family 

 of Aphidae within due bounds. 



"f" Sp. 1. lateralis. Hemisphcerica, nigra, nitida, thoracis laterihus, elytrorumque 



puncto pone medium rufis. (Long. corp. 1§ lin.) 

 Co. lateralis. Illiger.—Steph. Catal. 230. No. 2362. 

 Hemispheric, black, shining : thorax with its lateral margins rufous : elytra 



each with a rufous spot on the disc a little behind the middle : anterior 



tibiae pale. 



I formerly considered that my specimens of the following species 

 were synonymous with this insect, but upon a re-examination of them, 

 after a lapse of nearly twenty years, I am satisfied they are distinct : 

 but as Mr. Curtis, after two examinations of this genus, indicates 

 that he is in possession of indigenous specimens, the description is 

 here inserted. 



Sp. 2. Reppensis. Suhhemisphwrica, nigra nitida, thoracis lateribus punctoque 



versus apicem elytrorum rufis. (Long. corp. If lin.) 

 Co. Reppensis. Herbst, Col. v. pi. 59. f. 14. 



Subhemispheric, shining black : thorax with its lateral margins broadly 

 rufous : elytra ample, each with a more or less distinct rufous spot within 

 the apex on the lateral margin: anterior tibite and all the tarsi testaceous. 



Generally confounded with the preceding insect in the London cabinets. 



Found, though rarely, near Windsor, and also in Devonshire.
