212 INSECTA. 



used to establish several other subgenera, which we will unite with 

 the present one. They are composed of the Allantes, Doleres, Ne- 

 metes, &c. of Jurine, and of the Pristophose, formed of the third 

 family of the Pterones of that naturalist, with some others of Dr. 

 Leach. 



T. scrophularicE^ L. ; Panz., Faun. Insect., Germ., C, 10, the 

 male. Five lines in length ; black ; antennae fvilvous and some- 

 what thickest at the extremity; annuli of the abdomen, the 

 second and third excepted, margined posteriorly with yellow; 

 tibiaj and tarsi fulvous. It resembles a Wasp. 



The larva has twenty-two feet ; white, with black liead and 

 points. It feeds on the leaves of the Scrophulari?e. 



T. viridis, L.; Panz., Faun. Insect., Germ., LXIV, 2. The 

 same length; antennae setaceous; body green; spots on the tho- 

 rax and a band along the middle of the superior part of the ab- 

 domen, black. On the Birch *. 



De Geer has given us the description of a very singular spe- 

 cies in its form of a larva, that which he calls Mouche-d-scie of 

 the larve-limace, and to which he refers the Tenihredo cerasi,lj. 

 It is black, with blackish wings and brown feet. The larva is 

 extremely common on the leaves of various fruit-trees in the 

 gardens of France. On account of its form, Reaumur called it 

 Fausse Chemille Tetard. It is entirely black, and covered Avith 

 a ghitinous humour, which has also caused it to be compared to 

 a Snail. 



M. Peck, an American botanist, has also furnished us with 

 the complete history of another species, the larva of which is 

 similar. 



Others, in Avhich the antennae also consist of nine joints, differ 

 from the preceding in those of the males, which are pectinated on one 

 side. 



Cladius, Klibj, Lal.\ 



Some others, with a short, thick body, like that of the Hylotomae, 

 and considered as such by Fabricius, have from ten to fourteen joints 

 in the antennae, which are simple in both sexes. 



Athalia, Leach J. 



The following species are remarkable for their antennse, which are 

 composed of sixteen joints at least, pectinated or flabelliform in the 

 males, and serrated in the females. In this respect they lead us to the 

 Megalodontes, the first subgenus of the ensuing subdivision. 



* For the other species, see the authors just quoted- 

 f Lepel., Ibid., p. 57. 



X Lepel., Ibid., p. 21. In this genus, Dr. Leach only comprises those species 

 ■which are furnished with ten joints. Klug arranges them among his Emphyti.
