332 REPORT ON ZOOLOGY, MDCCCXLIV. 



especially as regards the mandibles and palps. Sc. thoracictis (with which 

 laticollis and minutissimws, Aubc, should he associated) is distinguished as a 

 peculiar genus, Cephennium, Mull. (= Megaladerus, Steph.) by the small 

 falcated upper jaws, and the nearly straight termination of the tongue, 

 while in the genuine Scydmeeni the tongue is deeply notched at the end, 

 almost bilobecl. In like manner Sc. truncatellus and abbrematettus, Er., are 

 separated as the genus E/itheia, Steph., on account of the elongated basal 

 joint of the lip-palps, and the peculiar form of the upper jaws, the long and 

 slender extremity of which is bent in almost at a right angle. The new 

 species are Sc. rotundipennis, from Syria, allied to Sc. collaris ; Sc. heholus, 

 from Hesse, resembles Sc. sparshalli ; Sc. styriacus, to be placed near Sc. 

 pubicollis ; Sc. intrusus, from Syria and Sicily ; and Sc. nanus (Sc. exilis, 

 Schaum. Anal.), a German species of the same division with Sc. wetterhallii ; 

 and Sc. vulpinus, from Arabia, which belongs to the division containing Sc. 

 tarsatus. Mannerheim (Bull. Mosc. 193) has added Sc. maklini, a small 

 fuscous species, with feelers formed as in Sc. claviger, to which it is most 

 nearly allied, found in company with Formica rufa. 



SILPHALES. Schiodte has published some observations on the family. 

 Necrophorus differs in having ten-jointed feelers, and peculiar organs of 

 sound. (See p. 307 preceding.) Necrodes departs from the rest of the family 

 in the form of the ovaries and of the small intestine. Schiodte thinks he 

 has found also an external character in the prothoracic spiracles being free 

 in Necrodes, covered in the other Silphse. I do not find this character 

 sufficiently determinate, for Silpha lacrymosa has them half covered, exhibit- 

 ing a gradual transition in this respect, as in others also it connects Necrodes 

 with the typical Silphse. The only alternatives are to cut up Silpha into a 

 considerable number of genera, or to include Necrodes also in that genus, 

 for which there is the greater reason as the Silphee are far from agreeing 

 among themselves in internal structure. Catops and Colon, according to 

 Schiodte's investigations, conform in internal structure to the type of the 

 Silphae, yet with some peculiarities, cliiefly iu the form of the male genital 

 organs, and the absence of a caecum. 



Fischer v. W. (Bull. Mosc. 40) has added four new species to Necro- 

 phorus, viz. lutiattis, from Sougary; frontalis, from Bucharest (the red- 

 spotted var. of germanicus) ; particeps, from Turkestan ; and mlcatus, from 

 Anatolia. 



Silplia ioptera, Kollar and Redt. (Hiig. Kaschm. 512), is a conspicuous 

 new species from Cashmere. 



In immediate connexion with Catops stands the new genus Adelops, 

 Tcllkampf, (Wiegni. Arch, i, 318.) It is distinguished by wanting the 

 compound eyes, the place of which is merely marked by a roundish while 

 spot with the appearance of a faintly-developed simple eye. A. hirtus^iss
