about equidistant from the suture and lateral mai-gin. The anterior 

 tibia? are strongly bidentate, the intermediate are minutely toothed, 

 each ventral segment has two setigerous punctures near the base, 

 the apical segment has four.

Carenidium Chaudoirii, n. sp. 



Of less elongate form than the last. The upper surface entirely 

 of a greenish V>lue, the under surface, legs, antennse, and the parts 

 of the mouth piceous. Head large, of a very minute shagreen- 

 like sculpture, eyes prominent, preocular angles less prominent 

 than in C. Darlingense, and the frontal canals moi'e diverging 

 behind, clypeus much the same, the labrum short, semi-circular, 

 and with four setigerous punctures. Thorax rather broader than 

 the head ; decidedly broader than the length, broadly cordiform, 

 rather broadly margined on sides and base, the basal lobe short 

 and truncate, the median line well marked, but not reaching tlae 

 base or apex, and the whole disk transversely scratched. Elytra 

 oblong-ovate, a little narrower than the thorax, about twice as 

 long as broad, minutely punctate and striate under a powerful 

 lens, a chxster of about nine punctures at the base and a regular 

 row of setigerous punctures along the latex"al margins. The anterior 

 tibise ai-e bidentate externally, the teeth as well as the spurs on 

 the inner side very strong and acute, the intermediate tibiae are 

 very strongly ciliated. 



Length, 13 lines.
