The general form of the body as in the Noviini; the prothorax and 

 ninth abdominal segment are crenated; setae-bearing processes from 

 the pleural lobe are developed as in CepJialoscymnus (?), but charac- 

 teristic for the group is the possession of setae-bearing processes, also 

 from the lateral margms of the tergum of the segments. Tlie meso- 

 thoracic and metathoracic spiracles are placed m the protopleurite, 

 and the protopleurite of these segments is incorporated in a sub tri- 

 angular extension from tergum, as in the Scymnini and Noviini; the 

 protopleural portion of the extension is clearly separated from the 

 tero-al part by the well-defined tergopleural suture. A setae-bearing 

 tubercle is found on this extension as in the Noviini. The hypo- 

 pharyngeal bridge is strong, the interior portion of the mandibular 

 basis is molar-shaped; the tip of the mandible is bifurcate; retina- 

 culum simple and thin-waUed.

The following genera and species of this group have been studied: 

 Micraspis 12- punctata Linnaeus (Denmark); Anisosticta 19-punctata 

 Say (Denmark); Megilla fuscilabris Mulsant (= M. maculata Degeer 

 (N. Amev,)), Hip podamia convergens Guerm (N. Amev.), Hi ppodamia 

 amhigua LeConte (California), Hippodamia glacialis Fabricius (N. 

 Amer.), Hippodamia 13-punctata Linnaeus (N. Amer., Denmark); 

 Adalia hipunctata Linnaeus (Washington, D. C), Coccinella 7-punctata 

 Lmnaeus (Denmark, Hungaria), Coccinella repanda Thunberg (Hawaii) ; 

 Coccinella variabilis IlUger (Denmark); Coccinella oculata Fabricius 

 (N. Amer.) ; Coccinella O-notataKerhsi. (N. Amer.) ; Coccinella sanguinea 

 Linnaeus (Cuba, Florida); Harmonia picta Randall (N. Amer.); 

 Neda marginata Lmnaeus (Mexico, N. Amer.); Cycloneda abdomi- 

 nalis Say (?) (Mexico, N. Amer.); Anatis 15-punctata Olivier (N. 

 Amer.); Synonyclia grandis Thmiherg (Java). 



The body is fusiform, in most genera with the greatest width at 

 metathorax; the sides of the abdomen are straight and the segments 

 diminish gradually posteriorly; the outhne of prothorax varies from 

 nearly trapezoidal, about twice as ^vide as long, with the largest width 

 posteriorly, to approximately crescent shaped. The ninth abdominal 

 segment is somewhat conical, half as broad as long, or longer, con- 

 siderably narrower than the eighth segment, laterally unarmed, never 

 serrated or crenated as in many preceding forms and never darkly 

 chitinized as in Microweisea. The mesothoracic and metathoracic 

 spiracles are situated in the large protopleurite. This is subtriangular 

 blunt, downwards directed, in some genera not limited dorsaUy by any 

 distinct tergopleural suture, in other genera with a distinct suture. A 

 setiferous tubercle is never developed in the spiracle-bearing region 

 as is the case in the Noviini and FJiyzobiini. The rest of pleurum has
