other joints narrow; antennae short, slender, the terminal joint 

 ovate; prothorax long, abruptly constricted at the middle, with a 

 very short neck in front; elytra long, confusedly punctate; anterior 

 coxal cavities open behind; tarsi about as long as the tibiae, the 

 penultimate joint short, lobed, not wider than the preceding, the 

 basal joint of the posterior pair about as long as 2-4 united, the 

 claws simple. 



Type, M. lobigeru. 



A single species from New Guinea forms the type of 

 this genus. It superficially resembles a Macr atria, but is 

 more nearly related to Egestria and Egestrina. The com- 

 paratively small head, with rather narrow neck; the short, 

 slender antennae, with a slightly elongated, ovate apical 

 joint; the simple maxillary palpi, with ovate terminal 

 joint; the mesially constricted, long, convex prothorax, 

 with short neck in front ; and the peculiarly armed posterior 

 tibiae of the male, are its chief characters. 



1. Macratriomima lobigera, n. sp. (Plate LXIV, fig. 11, J.) 



cJ. Elongate, rather convex, shining, thickly clothed (the legs 

 included) with long decumbent hairs, the head and prothorax also 

 with long, scattered, erect or projecting setae intermixed, those 

 behind the eyes very conspicuous, the hairs on the elytra brown, 

 the others cinereous; nigro-piceous with a slight brassy Lustre, 

 the palpi, the basal half of the antennae, and the tarsi in part, 

 testaceous. Head closely, finely punctate, smoother in the middle 

 posteriorly; antennae about reaching the base of the prothorax, 

 joints 3-5 subequal, longer than those following, 2 a little shorter 

 than 3, 6-10 subtriangular, equal in length, 11 onedialf longer than 

 10, ovate. Prothorax slightly wider than the head, the posterior 

 portion subparallel-sided and narrower than the transversely globose 

 anterior portion; densely, roughly punctate, finely but distinctly 

 canaliculate down the middle, and with a complete narrow basal 

 groove. Elytra somewhat convex, flattened on the disc anteriorly, 

 moderately elongate, rather broad, widest at the middle; closely, 

 coarsely, confusedly punctate, without trace of striae. Legs long, 

 the femora moderately clavate; posterior tibiae bowed, broadly and 

 obliquely lobed at the base within, and also armed with a compressed 

 sharp tooth just below this. Penis-sheath stout, long, acuminate. 

 Length (excl. pygid.) 5, breadth 11- mm.
