INSECT A — COLEOPTERA.

head is large and round ; the prothorax narrow, tumid in the middle of 
each side ; the legs long, the thighs somewhat club-formed and thickened ; 
the tarsi (in the accompanying woodcut) thin, not at all formed like the 
tarsi of the Ceramhycidw. Yet there is as little stated concerning their 
form as of the palpi. Ps. fonnicides, from Port Philip ; 2J'" long ; 
resembling an Anthiciis. 
Chrysomelin^. — Harris (Ins. of Massachus. p. 95, 109) mentions the 
following North American species : — Crioceris 4r-l{neata, 01., lives both 
as a beetle and larva on the potato plant ; the latter covers itself with its 
excrement like our C. merdigera. Hispa rosea, Web., {quadrata, F.) 
lives on the apple trees, upon Amelanchier ovalis and Pgrus arhuti- 
folia. Hispa suturalis upon Robinia pseudacacia. The larva of Cas- 
dda aurichalcea lives upon bitter-sweet (Solanum dulcamara), and 
upon different species of bind-weed, especially Convolvulus sepium. 
Galeruca calmariensis has been introduced from Europe, and increased 
so much, that the elm trees were eaten bare by their larvae, at Baltimore, 
in 1838 and 1839. G. vittata, F., is also very detrimental, especially to 
cucumbers, melons, &c. Haltica puhescens also feeds on the cucumber ; 
and various Cruciferce are attacked by II. striolata (Crioc. str., F.) ; 
and the H. chalyhea, 111., is destructive to the vine. The large orange 
coloured black spotted larvae and the pupae of Chrysomela ?>-maculata, 
F., live on the Asclepias syriaca ; and the white larvae, marked with 
dark dorsal lines, and square lateral spots, of Chr. scalaris, live upon the 
lime {Tilia americana) and elm ; Chr. coeruleipennis. Say, like our 
Chr. polygoni, from which it can hardly be distinguished, lives upon Po- 
lygonum aviculare. Eumolpus auratus, F., is found upon Apocynum 
androscemifolium. Clythra domicana upon sumach ; Cl. 4i-guttata upon 
oaks. Chlamys gibhosa upon bilberries. Cryptocephalus luridus upon 
wild indigo ; while most of the other species of the last genus live upon 
the different kinds of oak. 
Dr. Schmidt (Ent. Zeit. p. 27) has described a new German Lema, 
L. Suffriani ; it is most nearly allied to L. brunnea, and differs chiefly 
in the under side of the first two antennal joints, the breast, the knee- 
joint, and the extreme tip of the claws, being black. There is, however, 
only one individual (from Erfurt) at present known. 
Leptomorpha Jiliformis, Dej., from Sicily, has been described and 
figured by Germar (Faun. Ins, Europ. 22. 10). 
Gravenhorst and Scholtz have made some observations on the meta- 
morphosis of the Cassidce (Verhandl. der Kais. Leop. Acad. d. Naturf. 
xix. 11. 431, t. 73). They found, that upon the reflexed fork of the last 
segment of the abdomen, the rejected skin remains sticking, and that 
upon this, and not immediately upon the fork, the larva lays its excre- 
ment, which serves for its protection. The form of the excrement varies 
in different species. The larva of one species, belonging perhaps to
