COLEOPTERA. — COCCINELLIDiE. 395 



phus Weber, distinguished by the dilated, flattened, 3- articulate club of 

 the antennas, comprises several extraordinary species, having the 

 eb'tra furnished by a broad dilated margin, with the anterior tibiae 

 notched (Eumorphe de Sumatra Dumcril, Cons. Gen. pi. 21. f. 3., and 

 E. tetraspilotus Hope ; Griffith An. Kingd.). Hence, Mr. Curtis seems 

 to imagine there exists some kind of circular relation between Eu- 

 morphus and Mormolyce, thinking " it would be convenient, and even 

 natural to put Mormolyce at the beginning of the Coleoptera and Eu- 

 morphus at the end." The relation between these two genera appears 

 to me, however, to be nothing but the most remote analogy. My ex- 

 traordinary genus Trochoideus (Paussus cruciatus Dalvi.) evidently 

 belongs to this family. (See Trans. Ent. Soc. vol. ii. p. 96.) 



The third and last family of the Coleoptera, Coccinellid.i* Leach 

 (Aphidiphagi Latr.), corresponds with the Linnasan genus Coccinella, 

 comprising the well-known insects called ladybirds or ladycovvs, and 

 is distinguished by the hemispherical and convex form of the body 

 (^Jig.^9. 12. Coccinella 7-punctata) ; the pseudo-trimerous tarsi {Jig. 

 49. 18.) ; the hatchet-shaped terminal joint of the maxilhuy jialpi 

 (_/?j7. 49. 15.) ; the thorax very short,, transverse, and lunate; the 

 labrum (T?//. 49. 13.) broad, rounded at the sides ; the mandibles (7?</. 

 49. 14.) bifid at the tips; the labium is advanced (^^. 49. 16.) ; the 

 antennae often very short, with a 3-jointed flattened club {Jig.4;9. 17.) ; 

 the second joint of the tarsi is large, and deeply bilobed. 



The typical genus comprises insects with which every child is 

 acquainted : their domestic habits and pretty spotted appearance
