Notes on Aonyctevides. 25 



Elytra evenly rounded on sides, apex hardly produced, widely 

 rounded ; base feebly emarginate, humeral angles with a small 

 nodule ; disc with punctures rather large, open, not distinctly 

 separated from one another; interstices hardly raised, closely 

 •.set with small round setigerous granules, in single series, occa- 

 sionally duplicated in middle of third and fifth, and extending 

 •down declivity; sides granulate. Venter convex; apical seg- 

 anent with a median longitudinal impression in posterior half, 

 with a transverse sulcus at extreme apex. Legs simple. 



Dimensions. — ? 17x7 mm. 



Hab. — Victoria, Trawool, Kerrisdale (J. E. Dixon). 



Described from three females received from Mr. J. E. Dixon. 

 I have departed from my usual plan of describing only when the 

 -male is known, as in this case it does not seem likely to be con- 

 fused with any other species. 



I regard it as allied to T. tcnebricosiis, the rostral structure 

 :and general appearance are similar, but the present species is 

 •decidedly larger, and the granules much more evident. After the 

 'description of the female was written, and when the manuscript 

 was practically complete, I received a somewhat broken specimen 

 of the male, taken by Mr. Dixon in the same locality. 



Allotype (?. — Similar to female, apex subtruncate, with rather 

 -thick granulate flanges on each side, separated in the mid line by 

 .a small notch. Legs simple. Ventral segments flattened, the 

 intermediate ones rather short, the apical strongly concave, deep- 

 .^st along the posterior margin; ventral surface of apical dorsal 

 segment also concave; ends of forceps visible at sides of excava- 

 tion. Dimensions. — ^ 16 x 6 mm. 



I have endeavoured to dissect out the genitalia, but found that 

 unfortunately most of the internal structures had disappeared. 

 The eighth ventral segment was, however, represented by a pair 

 of well developed strongly chitinised forceps, the apices of which 

 project externally. The inner surface is curved inwards towards 

 the base to form a strong process extending almost to the mid 

 line, but apparently there is no fusion of the processes of the 

 two blades, though, as this portion is broken, it is impossible 

 to be sure, and it is likely that the gap was bridged by chitin, 

 as there is a small mass adhering at one side. In the allied 

 -species T. tcnebricosiis, the forceps are very similar in shape, 

 though smaller and the inner ends are connected by chitin, the 

 segment furthermore possessing another flat plate of chitin an- 

 terior to the bar between the inner processes of the forceps ;
