210 PERCY SLADEN TRUST EXPEDITION 
The series contains about 170 specimens, the majority of which were found between 
the leaf-bases of various wild palms. 
This species is dedicated to Mr H. P. Thomasset. 
Loc. Seychelles. Silhouette: high forest near Mont Pot-a-eau, cirea 1500 feet, 
a number of the specimens having been found between the leaf-bases of two growing palms 
(a Stevensonia and another, genus not recorded) on the 2nd and 7th of August 1908 ; 
forest above Mare aux Cochons, including 26 specimens from leaf-bases of one growing 
Stevensonia and six from those of another, both on Sept. 22nd. Mahé: forest above 
Cascade Estate, including over 40 specimens from leaf-bases of a single growing 
Stevensonia; summit of Mount Sebert, over 2000 feet, 11 specimens from leaf-bases 
of a growing Stevensonia; from near Morne Blanc, some from leaf-bases of a growing 
Verschaffeliia palm, others from those of a Stevensonia. Praslin : Coco-de-Mer forest in 
the Vallée de Mai, Cotes d’Or Estate, 11 of the specimens being from between the leaf- 
bases of a growing $ Lodoicea palm (‘‘ Coco-de-Mer ”). 
12, Paronucrus atomus, sp. nov. (Plate 14, figs. 4 and 11). 
Minutus, oblongo-ovalis, postice parum angustatus, nitidus, ferrugineus plus minusve 
infuscatus; capite prothoraceque dense minutissime punctulatis, hoe lateribus haud 
explanatis ; elytris strié suturali tenui, antice obsoleta, munitis, lateribus postice anguste 
explanatis, fortiter seriatim punctatis, seriebus parum impressis, intervallis fere planis, 
intervallo quoque lined punctulorum minutorum munito ; mesosterni parte elevata aream 
rhomboidalem, elevatione transversé tenui instructam, formante. Long. corp. ca. 1 mm. 
Head and prothorax appearing smooth, but under a compound microscope seen 
to be closely covered with an exceedingly fine, semi-reticulate punctuation. Prothorax 
practically not explanate at all at the sides, only under a high power is a very shght trace 
of flattening of the margin visible in front. Hlytra with the side-margins only very 
narrowly explanate, with a very fine sutural stria, often difficult to see and becoming 
obsolete in front, with regular series of large strong punctures, the series slightly 
impressed, the interstices almost flat and each bearing a series of minute punctures. 
Elevated part of the mesosternum (Pl. 14, fig. 11) forming a roughly diamond-shaped 
four-sided area, which bears a fine transverse elevated ridge, and behind this (towards 
its posterior extremity) a median elevation. The elevation of the median part of the 
metasternum is more marked than in the preceding species. 
The labrum (Pl. 14, fig. 4) is differently formed from that of P. carinatus or 
P. thomasseti, the sinuations of its anterior margin being deeper and more angular. 
The distinguishing features are the smaller size, shiny surface, the side-margins of 
the thorax not being explanate and those of the elytra only very slightly so, the inter- 
stices on the elytra being nearly flat, and the form of the mesosternum. 
The series consists of over 100 specimens. It is not confined to the high mountain- 
forests, as some specimens were found in lower country. I have no record of finding any 
specimen between the leaf-bases of a palm. 
Loc. Seychelles. Silhouette: high forest near Mont Pot-a-eau, circa 1500 feet; 
forest near Mare aux Cochons plateau, many specimens, including some recorded as found
