TWO HEMIPTEROUS INSECTS. 539 



division, Laporte's name Platycephala would be applied, 

 were it not that, as Mr. Westwood has pointed out, the name 

 has been pre-occupied ; I am rather inclined to think that 

 Serville's Brachyplatys is synonymous with Laporte's genus, 

 in which case Mr. Westwood's name Plataspis must be re- 

 jected, on the score of its being given after the publication 

 of Boisduval's ' Faune Entomologique de l'Ocean Pacifi^^,' 

 p. 627, 1832. 



Boisduval, in the work mentioned above, remarks that the 

 extremity of the scutellum in the male of Brachyplatys is 

 notched, Mr. Westwood however, in his excellent paper on 

 Coptosoma, published in the 2nd vol. of this series, 1 has 

 pointed out that it is the female that is so distinguished ; the 

 transverse folding of the anterior wings seems to me, to be 

 implied by Burmeister in his expression " die Haut zurneck- 

 geschlagen," as is the occurrence of two joints only to the 

 tarsus. My inexperienced eyes can only detect four joints 

 to the antennae in the species described below, but this, added 

 to the female having a blunt clypeus, as well as notched scu- 

 tellum, and both sexes having Hie femora much compressed, 

 as well as the last joints of the antennae, which are also hairy, 

 with a few other rostral characters, may perhaps indicate that 

 the insect is entitled to generic separation ; but I am unwil- 

 ling at present to give a name, lest it should be afterwards 

 quoted as among the things that were. 



I cannot see how Halin and.Spinola can possibly apply 

 the term Thyreocoris to a division, not a species of which is 

 quoted by Schrank as belonging to his genus. I am then of 

 opinion that the Telyra scarabaeoides, lateralis and helopio- 

 ides, three species figured by Wolff, as well as many of, if not 

 all, the species included by Germar in his definition of the 

 genus Odonloscelis, the type of which as given by Laporte 

 himself in his ' Essai' p. 74, is the Telyra fuliginosa of Fabr., 

 (Ursocoris fully inosus) Hahn, Arclocoris fuliginosus, Germar, 

 (p. 47.) I propose to name the genus (which seems almost as 

 peculiar to the new world, as Coptosoma and Plataspis are to 

 the old) Corimelaena, the type being the Telyra lateralis of 

 Fabr. and Cor. scarabaeoides, helopioides, niliduloides and 

 albipennis, being included in it ; it is unnecessary to take up 

 space in describing the characters, as they are already done 

 in such an able manner by Professor Germar, in his ' Zeits- 

 chrift,' I. pp. 36 and 37. Our first species, Graphosoma 

 Wilsoni, the specific character, merely, of which is given 

 beneath, comes near the G. semipunciatum of authors, from
