of long filaments, some of which, in a specimen which I possess, are 
at least four .inches long), Acocephalus, Bythoscopus, Eurymela, 
Selenocephalus Cselidia, Eupelix, Jassus, Ulopa, Cephalelus (C. 
infumatus, Perch ., Dorydium paradoxum, Burm. Handb. der Ent. 2. 
106), Dorydium (a new genus analogous to Cephalelus, but most 
nearly allied to Eupelix, to which Burmeister now applies this 
generic name, which had become a synonym of Cephalelus); the 
species, D. lanceolata, is from Sicily (and is remarkable for the very 
long head, pointed into a snout like a Fulgora) ; Ledra (I possess a 
second undescribed species from the East Indies), Xerophkea, 
Gypona, and Typhlocyba (Eupterix, Curtis.) 
In the order Coleoptera, ther Lamellicorn beetles are chiefly 
illustrated. An entire synopsis is given of a group of the Macleayian 
Dynastidse (consisting of the genera Chalcosoma, Megasoma K 
(Megalosoma, Burm.) ; Xylotrupes, Hope , Golofa, Hope, and 
Augosoma, Burm., (Centaurus, Jephtha and Ganymedes), Dynastes, 
M C L., also belongs to this group. The following isolated genera 
are also represented:—Eudinopus, a new genus of Scarabseidse, 
M‘L., founded upon a large South American species (of which I 
had prepared a figure for this work, which the author gives as new, 
but which was described by Sclireibers in the Linnsean Transactions, 
under the name of Scarabseus Dytiscoides.) 
Platygenia barbata, S and $ ; and Hypselogenia, Burm., 
(composed of two African Cetoniidse, Dipl, concava, and albo- 
punctata, G. P., which M c Leay unites with Ischnostoma of Gory 
and Percheron, from which, however, they are stated by Burmeister 
to differ in almost every character). 
Acropis, Burm., is another Coleopterous genus from South Ame¬ 
rica, founded upon a small xylophagous beetle, in which the eyes 
are placed upon lateral prolongations of the head as in Diopsis. 
Opsomala Serv., is the only Orthopterous genus figured. The 
genera Thrips, Plilseothrips Hal., and Heliothrips, and the Pediculi- 
deous genera Phthirus and Pediculus, are also elaborately illustrated. 
The work is entirely written in Latin, which renders it still more 
valuable, as well as indespensable to all who desire to possess beau¬ 
tiful figures united with correct structural details of rare and 
interesting genera. The two forthcoming numbers will be chiefly 
devoted to the Lamellicorn beetles, including a figure of the male 
of Mr. Cuming’s new Eucheirus (E. quadrilineatus, Waterh .) The 
genera Fulgora and Pyrops will also be illustrated in them.
