386 PERCY SLADEN TRUST EXPEDITION 
very certain indication of the sex in isolated specimens. The antennze which I have been 
able to examine microscopically, after mounting in balsam, all exhibit, without exception, 
the diagonal sloping suture in the club mentioned by H. Schaufuss. 
This species is easily distinguished from C. commumus by the different elytral 
sculpture, the longitudinal line on the head, and by the anterior thoracic tubercles ; 
it differs from the following species by the lesser number and smaller size of the tubercles 
before the declivity, whereas in the latter the granulations are continuous from base to 
apex. 
Loc. Seychelles. Mahé: 43 specimens, all from high damp forest between Trois 
Fréres and Morne Seychellois, 1500—2000 feet, 9 and 10. XII. 1908; probably from bark 
or wood of the endemic Wormia ferruginea, the “Bois Rouge,” though this is not quite 
certain. 
10. Cryphalomorphus confragosus, sp. n. 
Ellipticus, piceo-brunneus, tenue pubescens, capite globoso, minutissime granulato, in 
margine antico pilis griseis ciliata, linea media longitudinali, thorace latitudine longiore, 
apicem versus rotundato-angustato, dorso valde convexo, margine apicali tuberculis com- 
pluribus obsoletis notato, anterius valde scabrato, minutissimis pilis ornato, postice dense 
scabrato, medio utrinque oblique impresso ; elytris thoracem latitude prope zquantibus, 
et illo vix sesqui longioribus, convexis, apice rotundato, declivi, interstitiis granulatis 
a basi ad apicem. 
Long. 1°5 mm. 
In this species, the prothorax is narrower medianly than in the preceding, thus 
conforming more closely to C. communis, but the elytral sculpture is very different from 
either of the other species. In both the new species the antennz are exactly similar in 
shape and structure to those described by H. Schaufuss. 
Loc. Seychelles. Mahé: Cascade Estate, 800—1000 feet, I. 1909, one specimen. 
XyLEBORUS Hichh. 
11. Xyleborus semigranosus Blandf., Trans. Ent. Soc. London, 1896, p. 211. 
13 specimens. 
Loc. Seychelles. Silhouette: from near Mont Pot-a-eau, ca. 1500 feet, VIII. 1908, 
and Mare aux Cochons and forest above, IX. 1908; some specimens from fungus. Mahé: 
Cascade Estate, about 1000 feet, and from forest above, II. 1909. Sumatra, from 
tobacco. 
12. NXyleborus madagascariensis Schaut., Tijdschr. Ent., xxxiv. 1891, p. 23. 
I place these insects provisionally in the above species, as | am unable to obtain the 
loan of any specimens from Herr Schaufuss for comparison, but they do not differ 
materially from the description. About 20 specimens. 
Loc. Seychelles. Silhouette : found boring in the stem of an introduced species of 
Dracena, at the edge of the Mare aux Cochons plateau, over 1000 feet, IX. 1908. 
Madagascar.
