COCCINELLA HIEROGLYPHICA Linnaeus subspecies HUMBOLDTIENSIS Nunenmacher 



Coccinella humboldtiensis Nunenmacher, Ent. News, vol. 23, p. 448, 1912. — 

 Leng, 1920, p. 216. 



Differs from Coccinella hieroglyphica Linnaeus subspecies tricuspis 

 Kirby by less elongate form of the body, finer punctulation, and by 

 reduction of the black pigmentation of the elytra. Elytra orange 

 with a rhomboidal black spot ji and without other 

 spots, or with spots ji, 2, 3, and 4 + 5, or with K, 

 4, and 5, or 4 + 5, or with two transverse fasciae 

 (2 + 3 and 4 + 5), and the scutellar spot. Length 

 of the body, 3.6-4.2 mm. 



The genitalia of C. humboldtiensis (one male and 

 one female were examined) are identical with those 

 of C. hieroglyphica tricuspis. Nunenmacher (loc. 

 cit.) correctly pointed out the closeness of humbold- 

 tiensis to tricuspis, but, in my opinion, overestimat- 

 ed the value of the differences discovered between 

 them. Surprisingly enough, humboldtiensis pos- 

 sesses some similarities to the European hieroglyph- 

 ica, which the geographically closer subspecies 

 tricuspis does not possess. The similarities are the 

 form of the body and the shape of the elytral 

 markings.

COCCINELLA UNDECIMPUNCTATA Linnaeus 



Coccinella undecimpunctata Linnaeus, Systema naturae, p. 366, 1758. — Leng, 

 1920, p. 216. 



Oval, not strongly convex. Head with white spots near the eyes, 

 pronotum and the pronotal epipleura with quadrangular or triangu- 

 lar white markings in the anterior angles. Mesepimera and metepi- 

 mera white. Pronotum and elytra very densely and rather finely 

 punctulate, elytra yellow or brick red with the 11 typical spots 

 (fig. 30). Spots 2 + 3 and 4+5 fuse together forming two transverse 

 fasciae (var. boreolittoralis Donisthorpe) . Length of the body, 

 5-5.5 mm.
