Orchesiina. 



Orchesia Latr. 



One or more of the numerous small Chilean forms referred by 

 Solier, and Pairmaire and (lermain, to this genus will probably have to 

 be removed from it, but the available material (single specimens of two 

 or three species) is insufficient for the proper study of them. In the 

 Museum there is also an example of a minute, undescribed Micro- 

 scaphiform Orchesiid (smaller than 0. minuta Lea) from N. S. Wales 

 (ex coll. F. Bates), but as the antennae are broken the insect cannot 

 be described. An Orchesia, closely related to the Palaearctic and 

 Nearctic forms, is known from Guatemala, and one from Brazil is 

 now added, the first to be recorded from Tropical South America. 



1. — Orchesia hrasiliensis, n. sp. 



Cuneiform, brown or reddish-brown, the antennae and palpi ferruginous ; 

 densely, somewhat roughly punctate, clothed with rather long-, coarse, adpressed, 

 reddish-brown hairs. Antennae moderately long, joints 3-7 oblong-, sub-equal 

 in length, 3 a little longer than 2, 8-11 stouter, forming an elongate 4-JGinted 

 cltib, 8-10 slightly longer than broad. Eyes very narrowly separated. Pro- 

 thorax transverse, semi-circviiar, the basal foveae faintly indicated. Elytra 

 long, narrowing from a little below the base, the stitural stria deep. Length 

 4^-5, breadth 1^-1| mm. 



Hab. : Brazil, Eio de Janeiro (Fry). 



Four specimens, sex not ascertained. More elongate and larger 

 than 0. guatemalensis, the antennal joints 3-7 much longer, and 8-10 

 about as long as broad. These species belong to the sub-genus 

 Orchestera Guill., the type of which, O.luteipalpis Muls., has a shorter 

 antennal club, but is otherwise very similar to the American insects. 



MicRoscAPHA Lee. 



G. Horn, in his remarks on the two N. American species of 

 Microacafha (Trans. Am. Ent. Soc, xx, p. 144, 1893*), suggested the 

 name Crioscapha for his M. arctica, in the event of the two species 

 having to be separated generically. M. arctica, if I have identified it 

 correctly, can quite well be placed under Lederia Reitt. (1879), the
