the femora strongly elavate; basal joint of the anterior tarsi large, 

 fully as broad as the tibia, that of the posterior pair curved and not 

 very long.

One specimen. A robust, black. Bhining, sparsely cinereo- 

 pilose form, with a transversely subquadrate head, dark 

 antennae, a large, subcordatc prothorax, and confusedly 

 punctate, non-striate elytra, fche legs stout and in great 

 part testaceous. The basal joint of the anterior tarsus 

 is so much thickened as to appear, at first sight, a con- 

 tinuation of the tibia. .1/. truncata is allied to M. obsoleta, 

 Champ., from Costa Rica, from which it differs in the 

 broader, black head, the shorter antennae, the anteriorly 

 dilated prothorax. and the more densely punctured elytra ; 

 the posterior femora, too. are infuscate at the base and apex 

 only, not at the middle as in M. obsolela. 



o3. Macratria crassimanus, n. sp. (Plate I. XIV. fig. 23, 

 <$, anterior leg.) 



Elongate, shining (when denuded), the prothorax subopaque, 

 thickly clothed with fine, adpressed, fulvous or greyish pubescence, 

 with a few erect hairs intermixed; brown or reddish-brown, the 

 head usually rufeseent, the prothorax and metasternum sometimes 

 piceous, the palpi, mouth-parts, antennae, and legs (a large blackish 

 patch on the posterior femora, and the slightly infuscate posterior 

 tibiae and first tarsal joint, excepted) testaceous. Head transverse, 

 broadly truncate and feebly emarginate at the base, densely, finely 

 punctate ; eyes very large, oval, coarsely facetted ; antennae Blender, 

 long, joints 9—1 1 thickened and elongated, 11 one-half longer than 

 10; maxillary palpi moderately stout, joint 4 cultriform. Pro- 

 thorax about as wide as the head, oblong-oval, rounded at the sides 

 anteriorly, obliquely compressed on the Hanks posteriorly, densely 

 scabroso-punctate, the basal groove shallow. Elytra moderately 

 long, rather broad, suhparallel in their basal half: finely, densely, 

 confusedly punctate, with faintly impressed lines on the disc, the 

 usual rows of punctures altogether wanting, the submargina] stria 

 incomplete and only just traceable. Pygidium simple. Legs long, 

 the femora strongly elavate; basal joint of anterior tarsi very stout, 

 wider than the tibia in both se
