with 0. pclhicida, Mann., the deep-coloured individuals representing I he. 

 former, the lighter ones the latter ; O.v. similis, like O. funiida, and iu com- 

 pany with it under the bark of beeches ; Lathrobiitm dentatum, a very distinct 

 species. The author corroborates the occurrence of Quediits dilatatus in 

 hornets' nests. 



A number of new species have again been discovered by continued ex- 

 aminations of ants' nests. Of those enumerated by Mark el (Germ. Zeitschr. 

 v, 199-24-2), the nests of F. fuligiuosa yielded the greatest number : Myrme- 

 dottia similis, Bolitochara bell a, Homalota validicornis, divisa, confusa, hospita, 

 O.n/poda spectabilis, Aleochara yentilis ; in company "with F. cunicularia 

 were found Euryusa linearis, and probably coarctata also, and Sunius neglec- 

 ius ; lastly, Myrmedonia memnonia is a new species from Sicily, allied to 

 M. caualiculata. Mannerheim has added, besides, some new species 

 found with F. rufa : Homalota parallela (the same as H. talpa, Heer), 

 Oxypoda gihipes and Tacliyporus crassicomis. (Bull. Mosc. 178.) 



The g. Eotesthetus also has been enriched by the latter (ibid. 195) with a 

 new species from Finland, E. heriusculus, with the punctures rather dis- 

 persed, as in E. ruficapillus, but the impressed lines of the corslet strait, as 

 iu E. scaber ; it has been since found near Berlin by Grimm. 



Guerin (Revue Zool. 10) has described a number of uew Staphylini from 

 New Granada, including two new genera. Thyreocephalus is founded on 

 Xaiitholiiiiis lynceus, Er., along with a new species, Th. jeckelii, Guer., 

 distinguished from Xantholiuus by the upper lip, which is entirely horny 

 and many-toothed. Latona is most nearly related to Cryptobium : the last 

 joint of the jaw-palps pointed, one half shorter than the preceding, and 

 almost as thick at the base ; the two species, L. spinolee and erichsonii, 

 Guer., probably differ only in sex. The rest belong to established genera ; 

 Xaiitholinus puncticeps, impressifrons, nigriceps ; Cryptobium maxillosum, anale ; 

 Philontlitts succinctus, of the 5th, Ph. cupreus, amcenus, cyatiescens, of the 7th, 

 Ph. untennatus, cupripennis, of the 8th group, according to Erichsou's 

 method. 



Stapliylinus cinctus, Kollar and llcdt., (Hiigel Kasclun. 504, pi. 23, f. G) 

 is identical with St. leucomus, (Erichson Staph. 362.) 



PSELAPHH. Revision de la famille des Pselaphiens par le Dr. Aube. 

 (Ann. Soc. Ent. Fr. ii, 73.) An important work, by which this family is 

 enlarged, not only with many new species, but several genera. These are : 

 1. Ha mot us, nearly allied to Tyrus, differing by the spindle-shaped end- 

 joint of the jaw-palps, and the insertion of the feelers in a pit at either side 

 of the forehead. 2. Phamisvs : the last joint of the jaw-palps hatchet- 

 shaped, as in Bythiuus, but it has, like Tyehus, two equal claws to Lhe feet ; 

 the feelers inserted on a tubercle of the forehead. 3. Faronus, greatly resem- 

 bling Euplectus,but the feelers inserted on a tubercle of the forehead, and the 

 feet have two equal claws. The species are disposed in the folio wing order :
