 Mas, — Oblongus, gracilis ; mandibulis, capite et pronoto nigris 

 et sub lente tenuissime granulatis, granulis valde contiguis. 

 Caput transversum, lateribus fere rectis, angulis anticis sub- 

 oblique subtruncatis. Labrum porrectum. Mandibulee valde 

 elongatae, graciles, a pice acutae ; intus prope basin dente unico, 

 margineque interno denticulis novem vel decem armatis. 

 Antennae articulo 7mo intus in angulum acutum setiferum 

 producto, 8vo et 9no intus subobtusis, mentum latum 

 antice multo angustius et in medio emarginatum. Oculi 

 partim septo incisi. Protliorax transversus, capite parum 

 latior, lateribus subrotundatis, angulis posticis in dentem 

 parvum productis. Elytra prothoracis latitudine, angulis 

 humeralibus acutis ; sub lente punctis minutis oblongis ad 

 basin impressa, dimidio postico fere Isevi, nigra, obscure 

 castaneo (praesertim pone medium) tinctae. Pedes graciles, 

 tibiae anticae extus serrulatac denticulis majoribus aequidis- 

 tantibus dentibusque duobus apicalibus arniatse, tibiae inter- 

 mediae spina distincta extus in medio armatae ; posticae 

 tuberculo minutissimo medio. Corpus infra et pedes cas- 

 tanei, his supra obscurioribus ; tarsorum articulis 4 basalibus 

 dense luteo-setosis. 



Plate X. fig. 6, Cladognathus piceipennis, of the natural size; 6a, terminal 

 joints of the antennae; 6 h, mentum ; 6 c, eye partly incised by the septum. 



This species is closely allied to CL Spencii (Hope), and espe- 

 cially to CL gracilis, of which last it may possibly be regarded as 

 an extreme form of the male ; but, as in the last species, until 

 connecting links be produced, I must retain the opinion of the 

 propriety of regarding it as a distinct species.
