Brazilian Baring 151 



an elongate parabola; striae deep, grooved; intervals flat, with distinct and 

 close-set, confused punctures throughout; femora feebly inflated, rather finely 

 punctate; abdomen, in the type, with a feeble subglabrous basal concavity. 

 Length 4.0 mm.; width 2.0 mm. Brazil (Santarem). One specimen. 



On directly comparing obtecta with Thestonia sparsa, it is difficult 

 to associate them very closely in a generic sense, and yet many of 

 their structural characters are closely homologous. 



Garnia n. gen. 



We have here one of the most isolated type-forms in the present 

 series. The upper surface is glabrous, but medially beneath there 

 are plentiful minute glistening yellowish squamules. The beak is 

 slender and cylindric, but dilated at base, at least in the female, 

 the antennae at two-fifths, with the first funicular joint one-half 

 longer than the second, which is one-half longer than wide and 

 pedunculate basally, the club thick, subtruncate basally, ogival 

 thence to tip, distinctly segmented and not quite as long as the 

 preceding four joints. The mandibles are peculiar, being quadrate 

 and broadly truncate, though coming together on a straight line; 

 the prosternum is broadly and shallowly channeled and punctate, 

 the channel sharply limited at the sides anteriorly, but becoming a 

 broad and nearly flat surface, rounded behind and slightly over- 

 hanging the mesosternum. The coxae are widely separated. The 

 femora are slender, parallel, polished, unarmed and finely, remotely 

 punctulate; the tarsi are also nearly glabrous, and the small slender 

 claws are subcontiguous almost throughout their length, but 

 whether actually connate or not is indeterminate at present. The 

 following is the type of Garnia: 



Garnia militaris n. sp. — Rather stout, subevenly oval and strongly convex, 

 polished, black, the elytra each with a large red humeral spot in basal two-fifths, 

 extending more than half way to the suture, the humeral angle nubilously black; 

 beak ( 9 ) evenly arcuate, nearly three-fourths as long as the elytra, very slender and 

 cylindric, shining and sculptureless, rapidly thick, compressed and coarsely, 

 deeply sculptured in about basal third, separated from the head by only a feeble 

 depression; antennae black, glabrous and polished, the club minutely pubescent, 

 glabrous and polished on the obtuse base; prothorax large, a third wider than 

 long, the sides rather strongly converging and feebly arcuate, becoming gradually 

 more so beyond the middle to the gradual and moderate, punctate tubulation, 

 which is barely over a third as wide as the base; surface minutely, remotely 

 punctulate, the lobe strong, feebly sinuate medially at apex, with rather strong 

 lateral impressions, the scutellum well developed, subquadrate and transverse; 

 elytra oval, a fourth longer than wide, evidently wider than the prothorax and 

 fully three-fourths longer, striae moderate, deep and grooved, becoming fine and 

 distinctly punctulate on the red humeral regions; mesosternum and mes-epimera 

 with coarse and shallow punctures, the metasternum and met-episterna finely, 

 sparsely punctulate; abdomen convex, with rather small but strong, deep and 

 close-set punctures, very fine and dense on the fifth segment. Length 4.65 mm.; 

 width 2.9 mm. Brazil (Santarem). One female specimen.
