Brazilian Barusle 359 



strongly in basal half of the abdomen; the prosternum, with its 

 broad shallow impression, can scarcely be said to be canaliculate, 

 though the impression is limited along the sides by feeble tumidity 

 clothed with denser squamules. The hind margin is broadly trun- 

 cate, abutting closely against the mesosternum, and the coxae are 

 separated by nearly one-half more than their width. The legs are 

 well developed, the femora all much swollen and bristling with 

 erect setae, the fourth tarsal joint much longer than all the rest, 

 with well developed diverging claws. The prothorax is briefly 

 tubulate, the basal lobe small and rounded, the scutellum free, 

 obtrapezoidal and truncate, the elytra deeply grooved, the grooves 

 somewhat coarser and more impressed apically, and the pygidium 

 small, short, transverse and hairy. The two species are as follows: 



Body depressed, alutaceous, dark piceous-brown, with obscurely rufous legs; 

 beak three-fourths as long as the prothorax; antennae in both sexes medial, 

 the outer funicular joints transverse; prothorax (cf) fully as long as wide, 

 the sides in basal half straight and parallel, thence gradually evenly rounding 

 to the tubulation, which is much less than half as wide as the base, or ( 9 ) 

 evidently shorter than wide, the sides anteriorly more strongly rounding, the 

 tubulation subequal to half the basal width; punctures bearing the erect 

 setae rather strong and sparse, intermingled with fine and less remote punc- 

 tures, the surface feebly rugulose laterally; elytra one-half longer than wide, 

 or less (o 71 ), oval, with distinct humeral swellings and reentrant sutural 

 angle, evidently wider than the prothorax and three-fourths longer; grooves 

 not coarse but deep, punctate, a fourth as wide as the flat intervals, which 

 have single series of small and well separated punctures, bearing stiff erect 

 yellowish setae. Length 4.0-4.6 mm.; width 1.75-2.05 mm. Brazil (San- 

 tarem). Two specimens hispidula n. sp. 



Body almost similar throughout but a little larger, the outer joints of the antennal 

 funicle less transverse and larger; prothorax in the apparently male type 

 shorter, not quite as long as wide, similar in form and sculpture but with 

 the tubulation somewhat wider, though much less than half as wide as the 

 base; elytra similar, but with the grooves a little coarser, almost a third as 

 wide as the intervals, the remote uniseriate punctures of which are somewhat 

 stronger; under surface nearly similar, the femora more inflated and with 

 the erect bristling setae sparser. Length 4.7 mm.; width 2.15 mm. A 

 single specimen, probably from Para setosula n. sp. 



Sexual differences seem to be extremely feeble, the broad basal 

 impression of the abdomen being asexual, if I have correctly iden- 

 tified the female, which is much smaller than the male. Setosula 

 is founded upon a specimen which was without locality label in the 

 Levette collection, and it, as well as the type of Notesia latior, 

 which had the same status, were both quite mysterious to me, until 

 their analogues were discovered in the Smith Amazonian material. 



It is highly probable that Myelantia is allied to the Panaman 

 Calandromimus of Champion, but in that genus the mandibles are 

 slightly decussate, the scutellum large and transversely subquadrate,
