REPORT ON ZOOLOGY, MDCCCXLII: 
impressed longitudinal line. The following have an indented line on th^ 
anterior tarsi : Euryoda [Hepatodonta, Hope, but which name the author 
rejects, as the labrum has only five crowded teeth), with a short trans- 
verse 5-7 toothed labrum (O. analis, F. ; 4:-punctata, F. ; concinna, 
Dej.; versicolor, Dej.; Leprieuri, Dej. ; f estiva, Dej. ; ornata, Kl. ; co- 
lon, Kl. ; mirahilis, Brull. ; viridicyanea, Brull. ; all from the Old World). 
Chilonycha has a long three-toothed labrum, covering, in a great 
measure, the mandibles, and which, in the $, is produced into a spine ; 
it differs from Odontocheila, by its short arched body, and is South 
American : C. chalyhea, Dej. Phyllodroma, different from Odonto- 
ckeila by a short 1-3 toothed labrum ; habits rather similar : Ph. igni- 
collis, new species, probably Brazilian ; 0. curtilahris, and aperta, Kl., 
and semicyanea, Brull. Odontocheila, Lap., corresponding to Dejean’s 
first division of Cicindela ; Plochionocera, Hope (nodicornis), is 
quite correctly joined to it; 0. ventralis, distigma, Dej., sericina, Kl., 
rugipennis and tenebricosa, KolL, form a small peculiar group, with 
shorter body, elytra more or less impressed (eingedriickten), of black 
hue with silky gloss, inhabiting woods, not found upon leaves, but on 
the banks of water. Lastly, those having the second joint of the labial 
palpi thickened : Physodeutera, in which also the second joint of the 
maxillary palpi is swollen (O. Ado7iis, Lap., from Madagascar) ; Distip- 
sidera, Westw. ; Megalomma, Westw. (I published some criticisms on 
these genera in last year’s report) ; Apteroessa, Hope ; Promica, Dej. ; 
Euprosopus, Latr. — IV. Collyridce. The three known genera, Therates, 
Tricondyla and Collyris. — V. Ctenostomidce. The genera Psilocera, 
Brull. (this name having been previously applied elsewhere, Klug’s 
Pogonostoma is to be preferred) ; Procephalus, Lap. ; Ctenostoma, Kl. ; 
and Myrmecilla. The latter is founded on a small new species, M. pyg- 
mcea, from Brazil, differing from both the preceding by its longer labial 
palpi, while, in habit, it holds a medium between them. I must confess, 
that from our specimen of this Beetle, the difference does not appear to 
me very important, especially as it seems impossible, from a series of 
twelve species, which I have before me in the Berlin collection, to dis- 
tinguish, in any satisfactory way, between Procephalus, Ctenostoma, and 
Myrmecilla. 
Megacephala and Cicindela have been enriched with new species 
from several quarters. Megaceph. nigricollis, elongata, violacea, gra- 
cilis, Keiche (Rev. Zool. p. 239), are from New Granada. M. austral- 
asicE, Hope (Proceed. Ent. Soc. p. 45), from Port Essington ; the first 
species of this genus known in New Holland. 
Cicindela litterifera and suhtruncata, Chaudoir (Bull, de Mosc. 
p. 801), are from Astrabad, on the Caspian Sea ; Calochroa Strachani, 
Hope (Ann. Nat. Hist. x. 91, 14), from Sierra Leone ; Cic. ocreata, 
cupriventris, Favargeri, Reiche (Rev. Zool. p. 240), from New Granada ;
