Seychelles and Rangoon, 23 



WMtliouf llie serrations that extend some way down tJie 

 mandibles of L. <:eyJo7iic\im {cf. Matthew?:, pj. v. fig. A 4). 

 Maaillary folpi ot L. S( ychdleanum (fig. 31) with joint 2 

 much less curved and infliited outwardly, and the apical joint 

 shorter and blunter, t!ian those of L. ceylonicuvi (fig. 32) ; 

 ma.villary lobex of L. seycJitlleanuni slentU-r, sharply pointed, 

 with inner edge serrate near the apex [Matthews hgurcs the 

 lobfs in Lewisium as unarmed ; but a balsam-prepuration of 

 the maxilla of L. ccylonicum (tig. 32) shows about six minute 

 teeth near the apex, though these are scattered on thesuiface, 

 Tint arranged in a serrate edge as in L. seycheUtaiivm~\, 

 Fig. 33, copied troiu Matthews, shows the maxilla of Cato- 

 ptyx bvicriiifji for comparison. Labial palpi of L. seycheilt- 

 anuin (fig. 34) l}iiig nearly contiguous, not spre-id apart as 

 in L. ccy/unicum (tig. 35) *; fig. 3(5, copied from Matthews, 

 shows the parts in Catoptyx howrrngi. Therefore in t\»e 

 uiaxillse and labium L. seychdleauum seems in several points 

 to r( senible Catoptyx howrivgi more closely. Tarsi of all 

 three pairs in L. seycheUeanum broadly dilated and bilobed, 

 thu lobes pubescent.

Late ovale, postice perparum angustatum, valde convexutn, uiti- 

 dissinium, supra glabrum ; ])iceo-uigrum, prothoracis margine 

 antico pallide testaceo et pellucido, disco prothoracis ante scu- 

 tellum, scutello ipso, elytrorum sutura et marginibus exterioribus 

 (his anguste) piceo-rufis, anteunis pedibusque rufo-testaceis, 

 antennarum clavis baud nigricaiitibus ; prothorace fere impunc- 

 tato, elytris dense sat fortiter contuse punctatis. Lewisio ceylonico 

 simile, sed statura minus, et diftert in forma antenuarum, man- 

 dibulorum, &c., quse vide supra. 



Long. Corp. l-05-l*l mm. 



Broadly oval, slightly narrowed behind, very convex, very 

 shining, glabrous. Pitchy black, with anterior margin of 

 the thorax pale testaceous and pellucid, and the middle of the 

 disc of the thorax before the base, together with the scutellum 

 and suture of the elytra, lighter — i. e., pitchy reddish ; outer 

 margins of the elytra also narrowly reddish -[in a few speci- 

 mens the reddish colour is more extended and the whole body 

 is a little lighter] ; underside pitchy reddish, centre of meta- 

 sternum and first abdominal segment darker; Ipgs, mouth, 



* Too much reliance must not be placed on this diiiference, which may 

 be partly due to greater pressure of the coverylip in one preparation than 

 in the other.
