Numerous specimens seen, these varying greatly in the 

 colour of the body and legs, and in the intensity of the 

 metalhc suffusion of the elytra ; the antennae are usually 

 rufo-testaceous with the basal two or three joints infuscate, 

 rarely black in their basal half. This species, if correctly 

 identified by me, is closely related to S. viridipennis, differ- 

 ing from it in the more or less catenulate elytral interstices 

 1, 3, 5, 7, and 9 (the catenulation on 7 extending along their 

 entire length), and in the simple anterior and posterior 

 tibiae, and the slender basal joint of the antennae of the 

 male. The fiddle-shaped outer portion of the penis-sheath 

 (= tegmen), too, is characteristic of the present insect. 



22. Statira asymmetrica, n. sp. (Plate XIT, fig. 12, 

 penis-sheath, i^.) 



(^. Very elongate, narrow, shining; piceous, the elytra with a 

 translucent aeneous lustre, the head, antennae (the slightly infus- 

 cate basal joint excepted), legs, and under surface testaceous or 

 rufo-testaceous, the elytra with a few long bristly hairs. Head 

 rather small, short, almost smooth, the eyes large, narrowly separ- 

 ated; antennae very slender, extremely elongate, joint 11 about 

 equalling 8-10 united. Prothorax wider than the head, subcordate, 

 scarcely longer than broad, the basal margin prominent ; alutaceous, 

 sparsely, minutely punctate. Elytra very long, subparallel, less 

 than twice the width of the prothorax, rounded at the tip ; closely, 

 finely punctato-striate, the interstices flat on the disc, 3 widened 

 and with a series of about twelve, and 5 and 7 with from 8-10, deep, 

 subquadrate, setigerous impressions, 9 also with several others do^\^^ 

 the apical half, the spaces between the impressions longitudinally 

 raised and catenate -tuberculate from about the middle to the apex. 

 Metasternum and ventral segments 1-5 hollowed and thickly pilose 

 dowii the middle. Penis-sheath long, broad, asymmetric, twisted, 

 arcuately dilated on the right side at some distance before the apex, 

 the apical portion spoon-shaped. Legs very long ; anterior femora 

 thickened; posterior femora closely ciliate in their basal half be- 

 neath; posterior tibiae sinuously compressed, appearing hollowed 

 from a little below the base to near the apex, closely pilose within. 



Length 10, breadth 2| mm.
