2. Figulus seychellensis, sp. nov. 



Sat angustus, parallelus, niger ; mandibulis unidentatis; capite grosse baud profunda, 

 ad marginem anteriorem subtilius, punctato, in medio excavato, inter oculos postice 

 tuberculis 2 punctatis, antice tuberculis 2 impunctatis, margine anteriore sinuato, cantbis 

 oculorum ante oculos distincte sinuatis ; protborace quadrate, circa \ latiore quam longo, 

 lateribus postice crenulatis, angulis anticis parum, posticis conspicue, rotundatis, antice in 

 medio tuberculato, disco sulco medio fortiter punctato antice abbreviate, utrinque in 

 medio fere impunctato sed ad latera fortiter sat dense punctato ; elytris punctato-striatis, 

 striis internis baud fortiter punctatis, dente bumerali parvo, baud prominente ; tibiis 

 anticis <? et ? similibus {$ baud ad basin calcaris dilatatis). Long. corp. (cum mandib.) 

 9 — 9^ mm. 



A small, rather narrow, parallel-sided, shining-black form. Mandibles slightly curved, 

 each with one tooth on the inner margin rather near the base, and with the actual apex 

 blunt. The head bears 4 obsolete tubercles, 2 near the base between the eyes, and 2 

 impunctate ones situated just in front of the inner margin of the orbit. With the 

 exception of these anterior tubercles the bead is punctured, the punctures being large but 

 shallow, and becoming much finer and closer near the anterior margin. The margin of 

 the ocular canthus is distinctly sinuate in front of the eye, and the posterior angle of the 

 canthus is very obtuse. The prothorax is a little broader than long, with the front angles 

 slightly and the hind angles more widely rounded off; the lateral margins bear fine 

 crenulations towards the hind angles ; there is a small tubercle in the middle of the front 

 margin ; the median longitudinal impressed and punctured line does not reach quite to the 

 front margin ; on either side of this the inner part of the disc is smooth and bears only 

 extremely fine punctures, but the lateral parts are strongly punctured. The elytra are 

 strongly striate, but the striae (especially those near the suture) are not at all 

 strongly punctured ; tbe interstices are rather flattened ; the humeral angle is very 

 slightly toothed. The metasternum and first 4 ventral segments bear large punctures 

 laterally, but are smooth with only a few extremely fine punctures in tbe middle ; 5th 

 ventral segment wdth large punctures, especially near the margin. The length (including 

 that of the mandibles) is from 9 — 9^ mm. ; one specimen, bred in captivity from a larva, 

 is only 6f mm. I have 5 specimens. 



I have only been able to distinguish the sexes by dissection. In F. marginalis 



Ritsema""' the male has an abrupt and conspicuous semicircular dilatation on the inner 



* Ritsema described F. marginalis in Notes of the Leyden Museum, vol. i. 1879, p. 189, and added a note 

 about the difference of the ^ tibiae in the same publication, vol. xvii. 1895 — 6, p. 138.
