218 PERCY SLADEN TRUST EXPEDITION 
base by the humeral callus; 7 reaches to the base (5 and 7 curving very slightly towards 
one another, on either side of the callus, at the base); 8 and 9 are abbreviated a little 
before the base; at the apical end, 1—3 run to the apex, 4 unites with 9, 5 with 8, 
enclosing 6 and 7: intervals nearly flat, the outermost ones (and the inner ones towards 
the apex) slightly convex, with rather numerous fine punctures, and with a not quite 
smooth appearance in the general surface. Mesosternum with the raised lamella very 
narrow, linear. 
This species appears to resemble Cercyon nigerrimus Régimbart (Ann. Soe. ent. France, 
Ixxii. 1903, p. 49; known from Mauritius), judging from the description of that species. 
But M. Lesne, to whom I submitted a specimen of Cercyon fructicola for comparison, 
informs me that the unique type of Cercyon nigerrimus is larger, decidedly shorter and 
more convex, with the pronotum much less clearly punctuated, &c. 
74 specimens. 
Loc. Seychelles. Silhouette: near Mont Pot-d-eau, ca. 1500 feet, VIII. 1908; 
Mare aux Cochons plateau and forest above, ca. 1000 feet and over, VIII.—IX. 1908. 
Mahé: high forest of Morne Blanc, X. 1908; high damp forest between Trois Fréres and 
Morne Seychellois, 1500—2000 feet, XII. 1908 ; Cascade Hstate, ca. 1000 feet, and forest 
above, 1908—9; Mare aux Cochons district, 1500—2000 feet, I—II. 1909. Praslin : 
Cotes d’Or Estate, XI. 1908. 
The above list shows that in Mahé and Silhouette this species was taken principally 
if not entirely in the mountain-forests. It was often found in rotting fruit, especially 
oranges and “jak,” often in company with Cercyon unifornus, Dactylosternum msulare, &e. 
(see under those two species). 
20. Cercyon laticollis, Régimbart. 
Cercyon laticollis Régimbart, Ann. Soe. ent. France, lxxii. 1903, p. 48. 
13 specimens: the determination was first made by Monsieur d’Orchymont, and con- 
firmed by Monsieur Lesne, to whom a specimen was submitted. The specimens agree well 
with Régimbart’s description. The lateral margins of the prothorax, when viewed from 
the side, are seen to be slightly sinuate behind the anterior angles. On the elytra the 
Ist (sutural) and 2nd strize do not reach quite to the base, 3, 4 and 5 almost reach the 
base, 6 is abbreviated a little before the base, the callus being situated between its front 
end and the base, 7 reaches further forward than 6, 8 and 9 end some distance from the 
base, but 9 reaches further forward than 8: at the apical end, in at any rate most of the 
specimens, stria 4 unites with 9, and 5 with 8, enclosing 6 and 7: the large punctures 
of the strize lie in each case on the outer side of the stria : the intervals between the inner 
striz are nearly flat, the outer ones convex, the intervallar punctures being extremely fme 
and not close and bearing exceedingly fine hairs : the suture is darkened near the apex. 
I have distinguished a g and a ¢ by dissecting out the genitalia, but can see no 
external difference between them.
