Mr. G. C. Champion on various 



cJ . Ventral segint'iit 5 tlee|)ly arcuato-t'inargiiiate, 6 conical, 

 clett down the middle to near the apex, leaving a narrow 

 meiiiliranous space exposed. Tegmen with long, narrowly 

 separated lateral lobis, which are somewhat spoon-shaped 

 and flavo-ciliate at the tip. Penis-sheath rather slender, the 

 outer portion straight, narrowly produced at the apex, the 

 latter rounded. 



? . Ventral segment 6 short, simple. 



Length 8-11, breadth 4-0 mm. ( J ? .) 



Hah. Colombia, Bogota ; VENiizuELA ; Peru. 



Fitteen examples, including five males. A less robust, 

 smaller insect than A. bouplandi, the 'suiface constantly 

 metallic, the elytral markings somewhat different, the sub- 

 apical aiinulus always well defined, the legs more slender; 

 the (^ with the sixth ventral segment almost divided down 

 the middle, and the lateral lobes of the tegmen undilated at 

 the tip. 8ome of the sj)ecimens seen, both in the British 

 Museum and in the Hoj)e Collection at Oxford, are ticketed 

 A. {Dasi/tes) bonplandi ov A. ruhripennis, Latr. ; the three 

 at Oxford are without locality-label. 



11. A stylus nigrolimbatxis, sp. n. 



Moderately elongate, somewhat robust, shining, nigro- 

 pilose ; nigro-cjeruleous, the basal joints of the antennae 

 rufo-maculate ; the elytra with a space at the base (enclosing 

 a transverse reddi.->h spot), the suture thence to the tip, a 

 triangular or transverse patch at about the middle of the disc 

 (reaching the suture in one specimen), a rounded or sub- 

 triangular patch below this, a patch at the apex, and the 

 outer margin entirely o£ the ground-colour, the rest o£ their 

 surface orange-yellow. Head, antenna?, and prothorax much 

 as in A. cceruleotinctns^ and the elytra similarly sculptured. 



J . Ventral segment 1 hooked in the centre in front, 

 5 deeply, semicircularly eraarginate, 6 long, conical, with an 

 elongate-triangular notch at the tip, without trace of median 

 division. Tegmen with long, flattened lateral lobes, which 

 are rounded and flavo-ciliate at the apex. Penis-sheath 

 almost straight, somewhat abruptly narrowed at the apex, 

 the protruding membranous sac studded with minute points. 

 $ . Ventral segment 6 short, simple. 



Length 7^-9^, breadth 3^-4^ mm. (c? ? .) 



Hah. Ecuador {ex coll. Fry : ? ) ; Peru [type] [ex coll. 

 Fry: S ^). 



Three males and two females. This insect resembles the 

 smaller examples of A. bonplandi, from which it is separable
