PENTATOMIDES. Herrich Schaffer (Wanzenart Ins. vol. vii, pt. 2-6) 

 has given a revision of the Peutatomidae, which is at the same time a critique 

 on Spinola's arrangement. (See Report 1838, p. 256). Several new genera 

 are characterized and a number of new species figured. 



The new genera are, 1. Gastraulax : has a deep channel down the under- 

 side like Halys, but the insertion of the sucker-sheath as in Pentatoma ; two 

 new species, torquatus, from Manilla, and ihalassinus, from Guinea. 2. 

 Basicrt/ptus, distinguished from Aspougopus by the sharp-edged margin of 

 the head and the proportions of the sucker-joints ; established for Edessa 

 costalis, Germar, a Cape insect. 3. Platacantha : second abdominal seg- 

 ment with a broad spine extending beyond the middle hips ; breast without 

 keel and channel ; the only species, Edessa cerea, Germ., also from the Cape. 

 New species : Discocephala humilis, Klug, from Columbia ; Empicoris (= 

 Dinidor, Lap.), renggerii, and corrosus, from Paraguay; Ochlems (Spin.) 

 coriaceus, from Columbia; lutosus, Germ., and sordidus, G., from Brazil; 

 PJiyllocephala congesta, G., given by mistake as Brazilian, is Ph. senegalensis, 

 Lap., from Senegal ; Ph. distans, not from the interior of Africa as conjec- 

 tured, but from the East Indies; Dichelops (Sp'm.)jissus, Kl., from Senegal; 

 Aspongopus melanopterus, from Nubia, is Edessa viduata, F. ; Pentatoma 

 croceiipes, from Paraguay, also Brazilian ; scabricornis, from Brazil ; conjuii- 

 gens, from the Cape ; notulala, from Mexico ; seniwittata, from Pennsylvania ; 

 tristir/ma, from North America ; scissicollis, from New Holland ; spiniceps, 

 probably from South America ; Asopus numnmlaris (before described by 

 Erichsou), from New Holland , chrysopterus, from Guaham ; armiger, from 

 Bengal, furcellatus, Wolff. ; tristis (A. mcesta Germ.), from South 

 Africa ; ebulinus, from Brazil ; Edessa albirenis, from Carolina. 



It is to be observed that the species figured as Storthia llvida and Empi- 

 coris maculatus arc different from those so named by Perty, and new, that 

 the species given as Phyllocephala furcata, F., is Ph. histeroides, F., and that 

 Pentatoma acinorum, Germ., is not distinct from Ciinex versicolor, F. 



Schiodte (Kroyer Nat. Tidskr. N. R, i, 19) describes the young larva of 

 Pliltca corticata, Drury, scarcely 1| lines long ; he found it under the body 

 of the mother insect. 



LY^IGITES. Fieber (Entom. Mouogr. p. 112) has treated the genus 

 Ophthalmicus in the form of a Monograph, and enriched it with a number of 

 new species, mostly discoveries of Heifer's. The species are grouped as 

 follows : 1. Clavus distinctly divided from the corium, flexible at the seam 

 of junction: A. Prouotiun transverse, broader than long, trapeziform : a. 

 Scutcllum rounded at the end: 1. O.luridus, from the Euphrates; 2. 0.
