A series of about 150 specimens of this subcosmopolitan species. 
Loc. Seychelles. Silhouette: from near Mont Pot-a-eau, ca. 1500 feet, VIII. 1908 ; 
Mare aux Cochons and forest above, 1908. Mahé: from near Morne Blane, ca. 500— 
1000 feet, 1908; high forest between Trois Freres and Morne Seychellois, 1500— 
2000 feet, 1908; Cascade Estate, ca. 1000 feet, 1908—9; Long Island, VII. 1908; 
1906 (Thomasset); 1905; 1896 (Brauer). Praslin: Cotes d’Or Estate, 1908; 1905. 
Also found in the Seychelles by Alluaud (1892). Very common in rotting fruit, especially 
oranges and “jak,” where it is often found together with Cercyon uniformis, Cercyon 
fructicola, certain Nitidulide (especially Haptoncus ocularis Fairm. and Brachypeplus 
equalis Walker), and certain Staphylinide. As can be seen from the above list, it 
is found in many localities, from cultivated country near sea-level to the endemic 
mountain-forests. 
Aldabra: Picard Island (Fryer). 
Described from Mauritius ; distributed over all the warmer regions of the Old World. 
14. Dactylosternum pygmeum, Régimbart. 
Dactylosternum pygmeum Régimbart, Ann. Soc. ent. France, Ixxii. 1903, p. 45. 
16 specimens. This determination was first made for me by Monsieur d’Orchymont, 
and has since been confirmed by Monsieur Lesne, who found no difference between the 
specimen submitted to him and Régimbart’s type. The specimens agree with Régimbart’s 
description: he lays stress on the prothorax being perceptibly wider at the base than the 
elytra, but this is not a very perceptible character ; in contracted specimens the posterior 
angles of the thorax slightly overlap the shoulders of the elytra, and in extended speci- 
mens the thorax does sometimes appear a trifle wider at the base. 
This species is entirely distinct from even the smallest specimens of Dactylosternum 
insulare not only by its much shorter and more convex form, but by a number of other 
characters also. The punctuation is very much finer and much less dense, and quite 
different in nature; in D. insulare it consists of fairly strong simple punctures, but in 
pygmeum each puncture is very fine and has two minute fine scratches or striole radiating
