Neiv and little-known Lagriidae and Pedilidae. 237 



moderately thickened, that of the posterior pair curved, not very 

 elongate. 

 Length 4 J] mm. ($?) 



Hab. Colombia. 



Two specimens, acquired by the Museum in 1844. This 

 species, to judge from the description, must be very closely 

 related to M. filiformis, Laf., from Cumana, Venezuela, 

 which is said to have glabrous, shining lines along the 

 elytra! striae, the latter without distinct punctures. M. 

 sericea, Laf., based upon a single (^?) example from Nueva 

 Valencia, Colombia, seems to have a longer head, the basal 

 groove of the prothorax almost obsolete, the elytra parallel, 

 etc. The pygidium of the insect described is shaped as 

 in the female of M. incana, ( lhamp. (cf. B. C.-Am., Coleopt. 

 iv. 2, pi. 9, fig. 9a), but the curved posterior tibiae are 

 suggestive of the male sex.

 Macratria maxima, Pic, op. cit. 1902, p. 21. 



Hab. Brazil [types], San Antonio, Bahia {Fry). 



Two specimens (^$) in the Fry collection, labelled 

 M. canaliculata, H. Deyr., doubtless belong to this species, 

 which is one of the largest known members of the genus. 

 They are brown or blackish-brown in colour, with the palpi 

 and antennae, and the legs in part, ferruginous; the vesti- 

 ture close, long, and adpressed, with scattered long, erect, 

 bristly hairs intermixed; the head broad, subtruncate and 

 deeply cleft at the base; the prothorax broad, arcuately 

 dilated at the sides anteriorly, and much narrowed behind 

 (the laterally depressed basal portion thus appearing promi- 

 nent), the faint median channel mainly due to the arrange- 

 ment of the pubescence; the elytra long, subparallel in 

 their basal half, densely, confusedly punctate, not striate; 

 the pygidium feebly emarginate in ^; the basal joint of 

 the anterior tarsi moderately stout. M. maxima is said 

 by 1'ic to be a dark form of .1/. canaliculata wit h t be median 

 depression of the prothorax obsolete, e.g. as in the ! from 

 Bahia, the £ from the same locality belonging to M . cana- 

 liculata. The present species is more elongate than .1/. 

 robusta, Motsch., and has a broader, deeply cleft head, an 

 ovate prothorax, more finely punctate elytra, etc. Length 

 7-8 mm.
