328 REPORT ON ZOOLOGY, MDCCCXLIV. 



occurring about Leipzic (Staphyl. Fua. Leipzigs Umgegend, Eutom. Zeit. 

 307, 340, 372), and this not only from the new species he has discovered, 

 but more especially from his particular observations on their occurrence and 

 economy. 



In the environs of Leipzic the meadow land predominates, there is no 

 want of water either still or running, and the floods often occasion an 

 immense accumulation of insects under the leavings, of which many are 

 transported from considerable distances. Those kinds accordingly prevail 

 most, that belong to meadows, or to the water's edge. Of the Aleocharini 

 140 have been observed, of TacJiyporini 41, Staphyliniiii 85, Pcederini 33, 

 Slenini 44, Oxytelini, 34, Phlaocharini 1, Omaliani 23, Proteinini 7, Pieslitii 

 1, the total 410 species. The following are to be noticed as new or inter- 

 esting : TacJiyitsa chalybea, Rudd., on the banks of the Elbe and Mulde, often 

 in plenty ; T. lata, new species, still broader than T. atra, found running 

 about on moist clayey banks ; Homalota ripicola, new species, like H. labilis, 

 but distinguished by its clear blue-black hue without the grayish gloss, runs 

 about on sandy river-banks, like most of the genus; H. luyens, new species, 

 resembling Oxypoda curdculiua ; Oxi/pocJa leporinu, new species, allied to 

 0. lougiuscula ; Aleochara rujipennis, on sandy river-banks ; Silusarubiffinosa, 

 found about the oozing sap of elms and beech trees ; Mylleena grandicollis, 

 new species, constantly of a ferruginous hue ; Philontkus rubripennis, resem- 

 bling Ph. fulvipes. With LatJirolium elonyatum the author found males 

 exactly corresponding to Gyllenhall's description, these he considers a 

 second form of $ , no other differences being discoverable. L. quadratum 

 and terniinatum he regards as distinct species, for which, however, a suffi- 

 cient character has still to be framed. lu Ste/ius he observed the oesophagus 

 protruded in the living insect, without, however, being able to satisfy 

 himself whether it could be drawn in again. Tliinobius, new genus, closely 

 allied to Trogophlseus, and principally distinguished by the shards gaping at 

 the seam, so as to leave a triangular piece of the wings uncovered; Th. 

 c'diatuK, found beside water, (also by Grimm at Berlin). All the species of 

 Trogophltsws frequent wet places by the water-side, burrowing like the 

 Bledii. The author is disposed to unite Tr. riparhis and bilineatus, while 

 he distinguishes as Tr. obesus another species with lateral impressions on the 

 corslet, and reverts to Tr. inquilinus as a genuine species. Acrognathus 

 mant}ibularis and palpalis often appear in abundance in moist meadows, but 

 not before sunset. Lesteva bicolor and Anthophagus plagiatus have an oily 

 coat which repels water. The species of Meyarthrus occurred only in fungi. 



Two new species from the salt lake at Eisleben are described at the same 

 time, Philonthus salinus, very like Ph. fulvipes, and Troyophheus halophilits. 



The German Fauna has also received some accessions from the Thurin- 

 gian forest, (Kelluer in Entom. Zeit, 413.) O.rypoda iafu&cata identical
