Loc. Seychelles. Silhouette: Mare aux Cochons plateau, over 1000 feet, IX. 1908. 
It is the only specimen from Silhouette, and the only one from the Seychelles mountains, 
all the other Seychelles specimens having been found almost at sea-level.

Four specimens : determined by comparison with a typical specimen of abnormalis 
in the British Museum (Mr George Lewis’ Collection), with which they closely agree. 
By the kindness of Monsieur Lesne I have also been able to compare them with a 
cotype of Régimbart’s mollis: this is immature (Régimbart stated that almost all the 
specimens on which his description was based were immature), and consequently 
appears very different in some ways, being light yellow instead of the normal dark 
blackish-brown ; but a close examination has convinced me that it is identical with 
Philydrus abnormalis. Also Monsieur d’Orchymont has informed me that the Seychelles 
specimen submitted to him is identical with one from Tamatave in his collection. 
Philydrus abnormalis and Philydrus mollis are therefore the same: possibly the 
Sumatran Philydrus rubricollis Régimbart is also identical, as its description agrees 
and Régimbart stated that it might be so. Two other species, known from both 
Indo-China and Sumatra, appear to be closely allied, having the palps very greatly 
elongated in the same manner, &c.; they are Philydrus ferrugatus Régimbart and 
P. mgritulus Régimbart, described in the same paper with rubricollis (t.c., pp. 57, 58). 
The four specimens are dark brownish-black, with the labrum and the sides of 
the head in front of the eyes, the four margins of the pronotum narrowly, and the 
outer margins of the elytra more broadly, dark reddish; antennze and the greatly- 
elongated palpi testaceous. Beneath, dark reddish-brown or pitchy-reddish, the 
abdominal segments blackish with posterior margins dark reddish: surface dull, 
the metasternum, femora, and abdominal segments covered with very short, fine, pale 
pubescence: legs dark reddish-brown, femora somewhat infuscate, tarsi paler, testaceous. 
On the disc of the elytra two series of larger, setiferous punctures can be distinguished, 
the outer less complete and more irregular than the inner. ‘The anterior margin of 
the pree-frons 1s widely, very shallowly, and subangularly, emarginate. 
* Zaitzev proposes the name Lwmetus for this subgenus in his Catalogue, l.c. 
7 The name abnormalis is changed into abnormicollis in Zaitzev’s Catalogue: this must be by error, as no 
reason is given, and abnormalis is not preoccupied in the genus. Zaitzev’s reference to Sharp’s description is 
otherwise correct.
