All the legs are without tarsal spurs, but the claws are 

 furnished at the base with two small spines. 

 Length 37 millim. 

 A single specimen. 



This species is of peculiar interest, inasmuch as it appears 

 to partake of the characters of the two genera Otostigma and 

 Cormocephalus and in a measure to fill up the interval between 

 them. Although by the form of its tracheal apertures it is 

 undoubtedly referable to the former, as characterized by v. 

 Porath, yet it differs from all the specimens of this genus that 

 I have examined in the total absence of tarsal spurs and in 

 the presence of the two conspicuous abbreviated cephalic sulci, 

 features which are conspicuous for their constancy in Cormo- 

 ceplialus. 



It is unfortunate that, owing to the absence of the anal legs, 

 certain additional specific characters cannot be given ; but the 

 occurrence of the two conspicuous sulci upon the first tergite 

 and the large size of the pleural pores serve to differentiate 

 this species from all others with which 1 am acquainted.

Shining ; tergites castaneous, sternites, legs, and antennae 

 paler. 



Antemice long, attenuate, composed of seventeen segments ; 

 proximal three segments sparsely hirsute, the rest thickly 

 clothed with short hairs ; segments cylindrical, ultimate seg- 

 ment about equal in length to the penultimate. 



Head-plate almost circular, deeply but sparsely punctured, 

 and scantily hirsute, without elevated margins. 



Maxillary feet and sternite sparsely punctured ; anterior 

 margin of the sternite bearing four teeth, two in contact in 

 the middle line and one on each side ] basal tooth conspicu- 

 ous but simple. 



Tergites punctured, with the exception of the first seven 

 and last two, witli raised lateral margins ; the first marked 

 anteriorly with a conspicuous transverse groove ; the last 

 narrow, with lateral margins nearly parallel ; posterior mar- 

 gin between the joints of the legs convexly produced.
