228 PERCY SLADEN TRUST EXPEDITION 
blunt heel-like projection behind the base of the tarsus (whence the name calczger, “ heel- 
bearer”): anterior and posterior aspects are figured, Pl. 14, fig. 24, a and b (the anterior 
tibia of Paromalus gardineri is also figured, Pl. 14, fig. 23, for comparison, to show the 
more normal form). Externally the tibie are 4-toothed. 
In a single specimen the remarkable form of the tibize might well be considered to be 
an abnormality or monstrosity: but since there are three specimens all having them 
formed in exactly the same way, it must be taken to be normal. All three specimens, 
however, have been shown by dissection to be $, so the form of the tibize may be a sexual 
character. In addition to this, the species is characterised by its narrow subconvex form 
and dense punctuation, by having the frontal stria widely interrupted and the anterior 
thoracic stria complete, and by the form of the mesosternal transverse stria. It is 
absolutely distinct from either of the other Seychelles species. As to its affinities I can 
say nothing, not having sufficient knowledge of the genus: but I have seen no species 
with such tibize, nor closely resembling it in other ways, in the British Museum, nor have 
I read any description closely agreeing with it. 
Loc. Seychelles. Silhouette: endemic forest near Mont Pot-a-eau, ca. 1500 feet, 
VIII. 1908, 1 g (Type). Mahé: high forest of Morne Blanc, X. 1908, 1 ¢; Cascade 
Kstate, 800 feet or more, 1 ¢.

Bacanius ambiguus Schmidt, Ann. Soc. ent. France, 1893, Bulletin, p. 101; Alluaud, 
Liste Coléopt., p. 110; Kolbe, Mitt. Zool. Mus. Berlin, v. 1910, p. 21. 
A large series, determined by comparison with cotypes kindly lent by Monsieur 
Alluaud. There is considerable variation in size, length (not including the head) varying 
from less than 0°8 to 0°9 mm. 
Wings. I have examined these organs in 5 specimens (4 from Silhouette and 
1 from Félicité), and find them fully developed, about twice the length of the elytra. 
Loc.* Seychelles. Silhouette: from under bark of felled dicotyledonous trees 
among coconut-plantations near coast, Pointe Etienne, 17. IX. 1908, over 100 specimens ; 
from forest near Mont Pot-a-eau, ca. 1500 feet, VIII. 1908, 4 specimens; found under 
bark of partly decayed stem of a Dracaena (together with one Acritus daubani), Mare aux 
Cochons, IX. 1908, 5 specimens. Mahé: from a felled coconut-stem on Long Island, VII. 
1908, 2 specimens. Praslin: Cétes d’Or Estate, XI. 1908, 2 specimens. TF élicité: from 
forest, XII. 1908, 7 specimens. La Digue: taken in numbers in company with Acritus 
(Halacritus) algarum under seaweed on the sandy beach, 1892 (Alluaud). 
* Bickhardt, in Junk and Schenkling’s Coleopt. Cat., Part 24, Histeride, 1910, p. 85, gives ‘‘ Malacca” as 
the only locality of Bacanius ambiguus. I have before me a copy of Schmidt’s paper, referred to above, in 
which he describes the species from the Seychelles, and I know of no subsequent record of its occurring 
elsewhere. Bickhardt’s reference to Schmidt’s description is otherwise correct.
