and Species of Coleoptera. 13 



brevi. Pedes graciles ; femora antica erassiora, dente acuto 

 armata ; tihicf, posticse elongatae ; tarsi filiformes, postici articulis 

 primo et ultimo sequalibus ; unguindis longis, divarieatis. 



With the facies of Mesostena angusta this genus, according 

 to Lacordaire's arrangement, is more allied to the North- 

 American Triorophus, but the mandibles are not uncovered 

 by the labrum to the same extent as in T. Icevis^ for example. 

 The most striking peculiarity is the well-developed tooth on 

 the anterior thickened femora. 



CarcJiares macer. (PL I. fig. 3.) 



C. oblongo-ovatus, nitide niger ; labro, antennis tarsisque ferrugineis. 

 Long. 5 lin. 



Hah. Ngami, 



Oblong-ovate, black, shining ; labrum, palpi, antennae, and 

 tarsi pale ferruginous ; head rather narrow, finely punctured, 

 more closely on the constricted portion, between the antennary 

 orbits a semicircular impression 5 prothorax rather broader 

 than long, with minute scattered punctures ; elytra with 

 larger punctures and faintly striated ; body beneath smooth 

 and finely punctured ; intermediate and posterior femora mo- 

 derately clavate, their tibise moderately curved. 



CossypJius Umhatus. 



C. latiusculus, testaceo-piceus, late marginatus, marginibus leviter 

 rcticulatis ; elytris subseriatiin punctatis ; scutello transversim 

 triangulari. Long, 3 lin. 



Hah. Cochin- China. 



Hather broadly ovate, not narrowed behind, testaceous 

 pitchy, the body not broader than the pale diaphanous margin ; 

 prothorax finely punctured ; scutelluin transversely triangular ; 

 elytra irregularly punctured, the punctures larger than those 

 on the prothorax ; legs slender. 



Cossyphus * is one of the most isolated forms among the 

 Coleoptera. A foliaceous margin surrounds the thorax and 

 elytra as well as the head, which is imbedded under it. The 

 species are all very similar in form and coloui", but vary in 

 size ; they have no wings or they are useless for flight, 

 yet are found in Africa, north and south, India, Java, and 

 South Australia. C. Hoffmanseggii is a common species 

 under stones around Lisbon. The species here described 

 is remarkable for its broad diaphanous margin, apparently 

 indistinctly reticulated owing to its uniform coloration.
