184 CHILOCORUS. 



Chiloconis nigritus. 



Coccinella nigrita, Fabr. Suppl. Ent. Si/st. p. 79 (1798). 



Chilocorus nigritus, Muls. Spec. p. 463. 14. 



Orcus cerberus, Muls. Op. vn. p. 148 (1846) T. 



India, Malabar (Fry), Cochin China, China, Japan (Lewis) 

 Macassar (Wallace). The sides of the thorax are almost straight ; 

 the tibia? are obsoletely armed ; elytra faintly punctulate, without 

 deeper punctures at the margin ; (sometimes visibly and rather 

 coarsely punctulate). 



Chilocorus Schiodtei. 



Chilocorus Schiodtei, Muls. Sp>ec. p. 456. 5. (T). 



Sierra Leone, Guinea. I have also seen it marked "New 

 Zealand," but obviously in error". 



This species differs from its congeners by the thorax produced 

 in front of the scutellum so that the posterior margin forms an 

 obtuse V ; the punctuation is very characteristic ; each dot 

 (veiy lightly impressed) being surrounded by a circle of extremely 

 small points. The sides of the elytra are without a produced 

 margin, epipleurse extremely concave. 



Chilocorus discoideus,* sp. n. 



Hemisphserical, black ; head, body and legs testaceous ; elytra 

 red, largely bordered with black. L. 3 lin. Angola (Welwitsch), 

 Gaboon (Fry). 



Coloration of Chilomenes dorsalis. The clypeus is faintly 

 emarginate, strongly punctate; the thorax with basal line very 

 obsolete, sides rounded, sparsely punctate, anterior angles pu- 

 bescent; elytra with stellate punctuation, more evident towards 

 the margin ; presternum, broad, margined, mesosternum sinuate, 

 plicate, hardly separated from the metasternum, elytral epipleurse 

 parallel, foveolate. 



Chilocorus distigma. 



Coccinella distigma, Klug, Frman's Feise, p. 49. 197 (1835). 



Chilocorus rujiceps, Muls. Sj)ec. p. 457. 7. 



Tropical Africa (Senegal, Angola, Cape, Caffraria, Pt. Natal, 

 Abyssinia, Arabia). The size is very variable and to a certain 

 extent the shape and punctuation. It is allied to C. Schiodtei 

 by the stellate punctuation (which is sometimes almost merged 

 into ordinary close punctures), but differs by not having the 

 thorax produced behind ; the discoidal spot varies extremely in 

 size, and is altogether absent in an Angolan specimen belonging 

 to M. Welwitsch. 



Chilocorus cacti. 



Coccinella cacti, Linn. Syst. Nat. p. 584. 41 (1767).
