102 Mr. D. Sharp's revision of the species 



10. Tropisternus oculatus, Sharp. 



Sharp, Biol. Cent. Am., i., pt. 2, p. 58, pi. ii., f. 6. 



Mexico ; South America ; Colombia. 



This species may be readily distinguished from all 

 others known to me by the larger eyes ; the upper sur- 

 face is of an olivaceous tint, and the maxillary palpi, as 

 well as the ventral spine, are very elongate. In the 

 individual labelled " New Grenada " in my collection the 

 systematic punctures near the side of the thorax are not 

 concentrated into so minute a fovea as they are in other 

 individuals. The habitat Mexico is undoubtedly correct, 

 Mr. Godman having recently received two individuals 

 from Presidio ; the species existed in Doue's collection, 

 labelled " H. congener, South America " ; it was also in 

 Eeiche's collection, labelled " H. xanthopus, Eeiche, 

 Colombie," and in Laferte's, where it was ticketed "New 

 Grenada." 



11. Tropisternus flavipalpis, n. s. 



Superne niger, metallico-tinctus, antennarum basi 

 palpisque testaceis, pedibus runs, femoribus basi nigris ; 

 subtilius punctatus, pernitidus ; elytrorum linea margi- 

 nali subtiliter crenato-punctata, in dimidio basali laevi- 

 gata ; abdominis apice sat longe spinoso. Long. 11 mm., 

 lat. 6J mm. 



Mexico (from W. W. Saunders' collection). 



This is very similar to T. oculatus, but the eyes are 

 not so largely developed, and the ventral spine is less 

 elongate. Although I have described the epipleural line 

 as without punctures on the anterior half, yet by careful 

 examination, with a very strong lens, of a perfectly 

 cleaned specimen, very minute punctures can be detected. 

 The only individual I have seen is apparently a male, 

 but the tooth on the claws is placed at the extreme base, 

 on the swollen part of the claw, and thus is not easily 

 detected. 



12. Tropisternus chontalensis, Sharp.

 Central America. 



This is extremely close to T. flavipalpis, but the legs 

 are darker, and the apical ventral segment bears a very
