to about one foiirtli before apex ; two discal costate lines on 

 each elytron which are somewhat contiguous at base and con- 

 vexly united at about one fourth from apex, close to which 

 are two subraarginal similarly united costate lines, which are 

 very strongly raised and prominent at basal angle ; outer 

 marginal ridge levigate. Head and thorax beneath and legs 

 pilose, particularly at base of head, where there is a thick 

 tuft of ochraceous hairs. Body beneath and legs coarsely 

 punctate, less coarsely and prominently punctate on the 

 abdomen.

Var. — Elytra testaceous. 



I captured five specimens with the blue elytra and four 

 with the same testaceous in hue, all males. Its habits are 

 peculiar, not frequenting bloom, but flying swiftly along 

 banks or paths amid bush, when it may easily be mistaken 

 for a large blow-fly. I found it a very local and scarce 

 beetle. 



Mr. 0. Janson, to whom I submitted specimens, writes : — 

 " I should refer this species to Heterodita rather than create 

 a fresh genus (as genera in this group are, perhaps, already too 

 numerous), especially as the male is the only sex known at 

 present. It differs, however, in several characters, such as 

 the untoothed anterior tibia and small linear mesosternal 

 process. In some respects it more nearly agrees with Hetero- 

 phana^ and also, if these recently erected genera are really 

 distinct from Heterodita ^-^^'lih Mazoe (Peringuey) and Diploa 

 (Kolbe). 



" It would appear to be most nearly allied to //. Raeuperij 

 Schaum." 



Genudius dealbatus, sp. n. 



Bright, shining, black ; thorax with the basal angles 

 broadly sanguineous ; elytra with a broad submargiiuil whitish 

 fascia, broadening towards apex, where it is recurved and 

 convexly terminates. Head thickly and coarsely punctate. 

 Thorax coarsely punctate, most thickly so on anterior and 

 lateral areas, slightly foveate on each side of disk. Elytra 

 coarsely punctate and tesselate, their iimer margins mode- 

 rately costate ; two strongly costate longitudinal lines on disk, 

 commencing near base and terminating at about one tiiird 

 before apex ; humeral angles prominent and im punctate. 

 Thorax beneath and femora moderately pilose.
