394 SUPPLEMENT. 



Two examples resembling in form and sculpture the Panama specimens which I 

 referred (antea p. 101) to A. carinator, Har. They are larger (3 J millim.) and therefore 

 accord better with Harold's description. 



Ataenius abditus (p. 101). 



To the localities given, add : — Mexico, Teapa in Tabasco (E. H. Smith). 



OCHOD^US (p. 105). 

 Ochodaeus luridus (p. 106). 



The example from the Salle collection referred to this species is probably distinct. 

 Mr. H. H. Smith obtained at Omilteme in Guerrero four specimens of an insect which 

 agrees much more closely with Westwood's description ; these all have the short frontal 

 carina between the eyes, this carina being more or less depressed in the middle and 

 nearly separated into two transverse tubercles. The sculpture also agrees with the 

 description. The peculiar form of the left mandible described and figured by 

 Westwood, viz. bidentate at the apex and not sharply pointed as in both mandibles of 

 all other species of Ochodaeus, is certainly not shown in our examples ; but I think it 

 is clear that this is a mutilation, the figure on being regarded attentively evidently 

 representing a mandible in which the tip is broken off. The anterior tibiae are 

 unarmed at the inner apex in all the specimens. 



The two species will therefore stand thus : — 



1. Ochodaeus luridus. 



Ochodaeus luridus, Westw. Trans. Ent. Soc. Lond. n. s. ii. p. 67, t. 9. fig. 4 1 . 

 Eab. Mexico \ Omilteme in Guerrero (E. E. Smith) ; Guatemala, Tepan (Conradt). 



The single example from Tepan differs in the less densely punctured thorax and in the 

 clypeus being slightly produced and thickened in the middle ; it is probably the male. 



l (a). Ochodaeus ? 



Eab. Mexico (Salle). 



7. Ochodaeus ? 



Hab. Mexico, Amula in Guerrero (H. H. Smith). 

 A single example ; indeterminable. 



BOLBOCERAS (p. 111). 



Bolboceras sallaei (p. ill). 



To the Mexican localities given, add :— Amula in Guerrero 6000 feet (E. E. Smith).
