found under a stone in the Mammoth cave of Kentucky. Erichson has 

 added the remark that Leptiuus comes next to this new genus. 



Muls ant has observed that the larvae of several species of Silpha are 

 herbivorous. (Ami. Soc. Eut, Fr. ii, LIX.) 



HISTEIIES. New species, Hister parallelus, Kollar and Rcdt. (Hug. 

 Kasehm. 514), from Cashmere. Hololepta urvillei and paugami, Le Guillou 

 (Rev. Zool. 223), the former from Vavao, the latter from the Aroe Islands. 



TRICIIOPTERYGIA. A Monograph on Trichopteryx, by Allibert, is an- 

 nounced by Guerin, (Revue Zool. p. 51.) It is to contain 38 species, 18 

 of them new (the summary characters are given), to which two are added 

 subsequently (p. 133.) The characters are not sufficient to determine the 

 species intended, so that the author must be considered to have failed in the 

 object of securing priority for his names. 



Motschoulsky (Bull. Mosc. 819. Rev. Zool. 445) recognizes a division of 

 the genus Trichopteryx, Kby. (= Ptilium, Schiippcl) into three : 1. Ptilium : 

 body depressed, with silky pubescence, corslet not the least narrowed 

 behind, shards truncated, not completely covering the abdomen; e. g. 

 Pt. atomarium, Deg. fasciculare, Herbst., &c. ; 2. Trichopteryx .- body con- 

 vex, shining, corslet evidently narrower behind, shards pointed, covering the 

 abdomen completely; e. g. Tr. evanescens, Marsh., punctata, Gyll. ; 3. 

 Ptinella : apterous, elongated, shards strongly truncated, much shorter than 

 the abdomen ; (the eyes obsolete in some species, Pt. aptera). The author is 

 in error in assuming the genus Trichopteryx to have been established for 

 Silpha evanescens, Marsh. Trichopteryx is noticed by Kirby only in a note 

 to the ' Introduction to Entomology,' and the species named is Silpha 

 minutissima, Marsh. ( Dermestes atomarius, Deg. = Lathridius fascicularis, 

 Herbst.), that is, just the form which is here denominated Ptilium. Under 

 Ptilium the author cites Tr. testacea, Chevr., which has the corslet very 

 evidently narrowed behind ; and under Ptiuella, oblonga, Mark., and minu- 

 tissima, Web., Gyll., both of which have entire shards, and perfect wings. 

 In fact the latter is introduced again under Trichopteryx as trisulcata, Aube. 



Maunerheim (Bull. Mosc. 181) has found two new species in Ants' 

 nests, Tr. grandicollis, and longicornis ; of which the former at least is 

 frequent in other situations. 



NITIDULARI.E. The fifteenth volume of Sturm's ' Deutschlauds Insekteu' 

 is principally taken up with the continuation of this family, in which the 

 genera Cercus, Brachypterus, Carpophilus, Epur<ea, Nitidula, Soronia, Amphu- 

 tis, Omosita, and Pria, are treated of. His excellent figures will much assist 

 in determining the species, which is often difficult. 



Erichson (Germ. Zeitschr. v, 438) has completed his essay towards a 

 systematic arrangement of the Nitidularise, which appeared in a former part 

 of the same journal (see the Report for 1S42, p. 181) : 1. Genus Ecno)u'/<^ 

 two new species, concactts, from Christmas Bay, scaphula, from Nubia.
