INSECTA COLEOPTERA.

“belong to Spheniscus ; E. 6-fasciatus, F., to Doryphora ; on the other 
hand, the author is in error when he considers Er. (Zonar.) indicus, 
found so named in the Lund collection, as the real E. fasciatus, F. ; for 
first, Fahricius does not appeal to that collection, and secondly, from his 
description of the parts of the mouth, he appears to have had before 
him a Ilelopia. 
The natural history of the Triplax nigripennis (russica) has been 
described by Leon Dufour (Ann. d. 1. Soc. Ent. de Fr. xi. p. 191), the 
account of the larva is exact. It is curious, that the author will not 
acknowledge four or five black points in the situation of the eyes, as 
the organs of sight ; he found no labial-palpi (palp. lab. invisibiles). 
He met with the larva in the Boletus hispidus ; it goes into the earth to 
become a pupa, and the nympha remained attached to the larva case 
when burst open. The beetles are frightened by light. 
The reporter (Arch. 1842, i. p. 120) places Engis in this family ; 
it differs from Dacne, Episcapha, and Triplatoma, only in the first 
three tarsal joints having no covering of felt beneath. A new genus, 
Thallis, differing from Engis chiefly in the membranous lateral portions 
of the tongue being far protruded, is founded upon three new species 
from Van Diemen’s Land (ibid. p. 237). Phalacrus hrunneus of the 
reporter is from the same place (ibid. p. 239). 
CocciNELLiDiE. — Coccinella frenata, Scymnus ventralis, discolor, 
stragulatus, Corylophus tJioracicus, fasciatus of the reporter are new 
species from Van Diemen’s Land (ibid. p. 239). 
Endomychid^. — The reporter has characterized a new genus, Daulis 
(ibid. p. 241, t. 5, f. 5), which is most closely allied to Dapsa, espe- 
cially agreeing in the form of the antennal club ; but the third antennal 
joint is not elongated, and the last joint of the labial-palpi is strongly 
thickened ; the second tarsal joint is lobed. D. cimicoides is from Van 
Diemen’s Land. 
Lathridii. — Redtenbacher (Quaed. Gen. et Spec. Col. Austr. p. 21) 
has described a beetle, under the name of Rhopalocerus ferrugineus, 
as the type of a new genus, it is already known under the name of 
Monotoma Rondani, VilL, and for which a peculiar genus, Spartycerus, 
has already been established by Motschoulski, in the Bull. Mosc. 1837. 
On the remark, that this last name, if correctly spelt, has already been 
twice employed, Motschoulski altered it to Apeistus (Bull. Mosc. 1840, 
p. 186), a name which requires some improvement before its reception. 
Redtenbacher gives an excellent description of the beetle, but I cannot 
confirm his account of the tarsi being four-jointed ; I find only three 
joints, as in Monotoma, to which this genus is nearly allied, although 
it differs remarkably in the thick antennae, and the proportion of the 
joints of the palpi. The small basal joint, which Redtenbacher de- 
scribes, is perhaps the articulating head of the first joint. Motschoulski
