and pubescence very similar to tliat of the head, but not quite so 

 fine; ground-sculpture as on the head; each side with two distinct 

 setae. Elytra a little longer and wider than the thorax/transvcrso, 

 very finely, rather closely and somewhat asperatcly punctured, 

 finely pubescent. Abdomen more shining than the fore-parts, 

 bright reddish-testaceous, the fifth, sixth and anterior part of the 

 seventh segments, black glabrous and except for a few setiferous 

 punctures, impunctate. Middle and posterior tibiae each with 

 three setae of which the middle is the strongest. 



cj. Head anteriorly with a small erateriform tubercle, from which 

 arises a seta. Antennae a little longer than in the $. Thorax 

 with a small fovea before the scutellum, the disc with a fine longi- 

 tudinal groove throughout. Elytra with the postero-external 

 angle usually furnished with a keel. Abdomen with the sixth 

 abdominal segment only black; the third to the sixth dorsal seg- 

 ments elevated in the middle line, appearing tectiform on transverse 

 section; the third segment with a small semicircular cmargination 

 in the middle of the posterior border; the fourth with a stout 

 triangular tubercle at the base, the fifth with a broad triangular 

 process arising from the base, the apex pointed and extending back- 

 wards for about a tliird of the length of the segment ; * the sixth 

 with the posterior margin produced backwards in the middle lino 

 as a pointed tooth reaching the level of the middle of the seventh 

 segment; the eighth narrowed posteriorly, the posterior margin 

 produced backwards in the middle line as a short blunt tooth; 

 first ventral segment embracing the sides- of the third dorsal, its 

 upper free edge bluntly pointed posteriorly. Viewed from above 

 it appears as a lamina sjiringing from the second dorsal segment 

 and extending parallel to the third, its true relations are however 

 revealed on dissection. 



The $ of this species has quite the facies of A. crassi- 

 cornis F. The (^ characters are reminiscent of Myrme- 

 donia. The structure of the mouth-parts is that of Athefa, 

 with the exception that the 4th joint of the maxillary 

 pal})i is more than half tlie length of the 3rd.

122. Atheta (Dimetrota) carpophila, n. sp. 

 Black, greasy-lustrous; ilio thorax pitchy-red; the second, third, 

 fourth, posterior portion of the seventh and whole of the eighth 



* The development of these processes on the fourth and fifth 

 segments is very variable and they aie rudimentary in specimens 

 in which the postero-external angle of the elytra is simple.
