centrally impressed ; the second distinctl_y longer tlian broad, dull 

 and finely aciculate ; the quadrate third coriaceous, and the 

 following shining ; anus with stramineous markings ; terebra as 

 long as or slightly longer than the basal segment. Legs testaceous, 

 hind ones rufescent ; coxae and trochanters pale ; hind tibice 

 basally paler and apically subinfuscate. Whigs of normal breadth ;. 

 radix and tegula) flavous ; stigma piceous. 



Length 6 millim.

This species bears a remarkable resemblance to the Paltearctic 

 T. 2^uIchnconiis, Brisch. {T. com/)ressus, Thorns.), Structurally it 

 is rendered certainly distinct by the deeply impressed notauli and 

 much more strongly emarginate occiput ; otherwise it differs in 

 having only the apex of the clypeus pale, the third and fourth 

 flagellar joints black, the areola trans-aciculate and less parallel- 

 sided, the basal segment of the abdomen entirely rufescent and 

 the third immaculate black, with the second distinctly longer, 

 and the third coriaceous ; the head is broader, the anus more 

 compressed and the size a little largei'. 



Genus BOLODERMA, gen. nov. 



Eyes internally entire ; occiput distinctly bordered throughout r 

 clypeus scutelliform, and apically subproduced and narrowed; 

 lower mandibular tootli much the longer and both apically obtuse. 

 Antenna:> as long as the body and apicalh' subsetaceous, with a 

 broad wliite band beyond the centre. Notauli fine and deeply 

 impressed ; mesopleurte basally tuberculate below, with no sulci ; 

 metanotum entirely glabrous, with no indication of carinse ; 

 petiolar area perpendicular, concave and centrally subtuberculate 

 above ; supracoxal carinte alone indicated ; spiracles linear and 

 not small. Abdomen subpetiolate ; basal segment explanate 

 slightly throughout, elongate, with the spiracles distinctly before 

 its centre and placed in a discal hump ; hypopygium exteiiding to 

 the subcompressed anus. AVings with no areolet ; nervelet short 

 and distinct ; second recurrent nervure emitted beyond the 

 submarginal ; nervellus subopposite and intercepted exactly in its 

 centre. 



At first I was at a loss regarding the natural position of this 

 genus, and it is only a knowledge of the very rare Arotes albicincias, 

 G^^aA^, which suggests this as the most natural place tliat can at 

 present be assigned to it. To Arotes it appears allied in general 

 facies and sculpture and in the distinctly longer lower mandibular 

 tooth, though the face is simple. It is similar to the antipodean 

 genus Probololdes, Mori. (Ichn. Brit, i, p. 100), in the shape of 

 the metathoracic spiracles and the incrassate basal segment, 

 though the hump is here before its centre, and the areolet and 

 metathoracic areoe are wanting. I consider it most closely related
