Cercyon laticollis Régimbart, var. ? 
A single specimen, apparently immature, differs from the preceding series. The sides 
of the elytra are more rounded and their greatest width is behind the base, instead of their 
being widest at the base and tapering gradually ; the inner strize are strongly impressed 
right up to the base, instead of becoming faint in the region of the scutellum, and the 
intervals appear slightly less smooth. The sides of the pronotum are not sinuate behind 
the anterior angles. The scutellum is narrower at the base and proportionately more 
elongated. At first it seemed probable that this might be the 2 of C. laticollis: but as 
stated above dissection has revealed the presence in the series of that species of 3 and 2 not 
differing externally, and the true position of this specimen must therefore remain doubtful. 
Loc. Seychelles. Silhouette: Mare aux Cochons, IX. 1908. 
21. Cercyon uniformis, Sharp. 
Cercyon uniformis Sharp, Trans. Ent. Soc. London, 1890, p. 357. 
Determined by comparison with the type. A series of over 160 specimens, showing 
considerable variation in size, but apparently constant in coloration, &c. 
Loc. Seychelles. Mahé: high forest of Mornes Blane and Pilot, ca. 2000 feet, 
including some from strong-smelling rotting fruits of Pandanus seychellarum on summit 
of Morne Blane, X. 1908; country above Port Glaud, 500—1000 feet ; Cascade Estate, 
ea. 1000 feet, and forest above, large numbers, 1908—9; Mare aux Cochons district, 1000 
—2000 feet, including some from forest on summit of ‘“‘ Montagne Anse Major,” 1909. 
Silhouette: near Mont Pot-ai-eau, ca. 1500 feet, VIII. 1908; Mare aux Cochons, over 
1000 feet, 1908. | 
I found this species very common in rotting fruit, especially oranges and “jak 
(Artocarpus integrifolia), where it is frequently obtained in company with Dactylosternum 
msulare, Cercyon fructicola, &c. It can be seen from the above locality-list that it is also 
found in the dampest endemic forests and at the highest elevations, which is remarkable, 
” 
as it is probably an introduced species. It is recorded also from Ceylon and India. 
22. Cercyon sp. 
Length (not incl. extended head), 14 mm. Oval, with the greatest width a little 
before the middle of the elytra, narrowed before and behind with the apex of the 
elytra bluntly rounded, convex ; head and pronotum shining, elytra subopaque. Head 
black, with the extreme anterior margin of the epistome very narrowly testaceous ; 
palps and antennz pale testaceous, the latter with blackish clubs: pronotum pitchy- 
blackish, with anterior margin narrowly and lateral margins more broadly testaceous, 
and posterior margin obscurely reddish. Elytra with the basal quarter obscurely reddish, 
the extreme base and scutellum being darker (blackish, especially in the middle): from 
about + to about 2 the length is occupied by a broad black band extending from 
about the region of the 8th stria to the suture, and stretching obliquely inwards and 
backwards ; in front this black band is vaguely bounded, shading gradually into the 
basal reddish portion, but behind it is more sharply bounded; behind it the whole 
apical portion of the elytron is pale yellowish testaceous, excepting the interval between
