252 PERCY SLADEN TRUST EXPEDITION 



The occurrence of this blind and wingless genus in the Seychelles is very interesting. 

 It was originally described from France ; several European species have been described, 

 and 1 from California : the allied Illaphcmus was described from Australia. The following 

 is a description of the specific characters of the Seychelles specimen as far as they can be 

 made out. 



39. Anillus sp. ? 



Length, just under 1 mm. Form narrow and elongate. Colour pale yellowish- 

 testaceous. Antennas with joints 1 and 2 large and subturbinate, joint 3 small and 

 subturbinate, joints 4—10 almost spherical, becoming gradually larger towards the apex of 

 the antenna, joint 1 1 subconical. Prothorax a little broader than long, narrowed behind 

 and subcordate, the anterior angles somewhat rounded, the posterior angles nearly right 

 angles : each posterior angle is seen under a high power to be slightly but quite distinctly 

 emarginate at the actual corner : disc of the thorax appearing smooth and impunctate, but 

 with very high magnification a few extremely minute punctures bearing very short setse 

 can be seen. Elytra slightly broader than broadest part of prothorax, with sides sub- 

 parallel, narrowing slightly behind : lateral margins under compound microscope seen to 

 be serrate, more markedly near the shoulders : surface smooth : near the lateral margins 

 are some large circular punctures, from the centre of each of which arises a very long and 

 very fine outstanding seta : there are 3 such in the humeral region and several in the 

 posterior part of the elytron ; the longest and most conspicuous setae on each elytron ar-e 

 (1) the middle of the 3 humeral, (ii) one arising about ^ the length of the elytron from its 

 apex, and (iii) one arising at the posterior extremity of the elytron, some distance from the 

 suture. 



Loc. Seychelles. Fdlicitd : from forest, 14—17. XII. 1908. 

 Note. Carahid. gen. et sp. indet. 



A single damaged specimen : the absence of the head renders it impossible to fix the 

 genus with certaint}', but the remainder of the insect is intact and has the appearance of 

 being possibly a Stenolophus. Length (without the head) 3^ mm. Thorax brownish- 

 testaceous, considerably broader than long, slightly narrowed towards the base, with the 

 posterior angles obtuse and rounded ; surface impunctate in front, impressed on either side 

 and finely punctured at the base. Elytra at the base a little broader than the base of the 

 thorax, each witli 8 striae continued to the apex and with a very short stria at the base 

 between the 1st and 2nd discal striae, and with smooth interstices : pitchy or blackish with 

 the 1st interstice testaceous throughout, with a testaceous vitta extending along the 6th 

 interstice, broadening out at the shoulder and behind the middle, and with the lateral 

 margin narrowly testaceous.
