78 INSECTA. 
Pediculus melitte, and I was formerly of his opinion. M. 
Walckenaer, in his “ Mémoire pour servir 4 Histoire Naturelle 
des Abeilles Solitaires du genre Halicte,” has brought forward 
all the facts relative to this subject of controversy. I also 
have since spoken of it in the article Méloé of the Nouv. Dict. 
d’Hist. Naturelle. The same insect is the type of the genus 
Triongulin of M. Leon Dufour—Ann. des Sc. Nat., XIII, »., 
B—already noticed in our exposé of the Parasita. But the 
late researches of MM. Lepeletier and Serville, who by 
isolating several females have obtained larvee from their eggs 
exactly similar to those described by De Geer, or Triongulins, 
compel us to believe that they are those of Meloes. We know 
that several Heteromera deposit their ova in the nests of various 
Bees. Is it not possible that this may be the fact with respect 
to the Meloes, and that their larve live on these Bees, until the 
period at which these hymenoptera insure the existence of their 
young ones, and that also of their enemies, which then establish 
themselves in the provisioned cells ? 
M. majalis, Oliv. Panz.; Leach, Ibid., 1,2. The antenne 
regular and almost similar in both sexes; body bronze and cu- 
preous-red mixed; head and thorax deeply punctured; elytra 
scabrous; cupreous and transverse bands on the abdomen. It 
had been considered as the J. majalis of Linnweus, a species 
which is found in Spain and Roussillon *. 
All the Heteromera of the following subgenera are furnished with 
wings, and their elytra, as usual, extend longitudinally over the ab- 
domen. 
Of these subgenera we will first describe those in which the elytra 
are not abruptly subulate near their posterior extremity, and where 
they completely cover their wings. In 
Terraonyx, Lat—Apawus, Fab.—Lyrra, Aliig., 
The maxilla, as in Cantharis and Zonitis, are not prolonged and 
terminated by a silky thread, and curved inferiorly. The penultimate 
joint of the tarsi is emarginated or almost bilobate, and the thorax 
forms a transverse square. These Insects are closely related to the 
Cantharides, and are peculiar to the western continent t. 
Cantuaris, Geoff. Oliv.—Menoer, Lin—Lyrra, Fab. 
All the joints of the tarsi entire, and the thorax almost ovoid, 
slightly elongated, narrowed anteriorly and truncated posteriorly, 
by which this subgenus is distinguished from the preceding one. 
The second joint of the antennz is much shorter than the following 
one, and the last of the maxillary palpi is evidenty larger than those 
* For the other species, see Leach, Monog., cit., that of Meyer Fabricius, Olivier, 
&e. The M. marginata, Fab., is a Galeruca.
