<$ . Ventral segment 5 deeply arcuato-emarginate, 6 conical, 

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

 membranous space exposed. Tegmen with long, narrowly 

 separated lateral lobes, 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 4-5 mm. ( tf ? .) 



Bab. Colombia, Bogota ; Venezuela ; Peru. 



Fifteen examples, including five males. A less robust, 

 smaller insect than A. bonplandi, the surface constantly 

 metallic, the ( elytral markings somewhat different, the sub- 

 apical ami ulus always well defined, the legs more slender; 

 the S with the sixth ventral segment almost divided down 

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

 the tip. Some of the specimens seen, both in the British 

 Museum and in the Hope Collection at Oxford, are ticketed 

 A. (Dasytes) bonplandi or A. rubrtpennis, Latr. ; the three 

 at Oxford are without locality-label. 



11. A stylus nigrolimbatus, sp. n. 



Moderately elongate, somewhat robust, shining, nigro- 

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

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

 a transverse reddish 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 of the ground-colour, the rest of their 

 surface orange-yellow. Head, antennas, and prothorax much 

 as in A. cceruleotinctus, and the elytra similarly sculptured. 



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

 5 deeply, semicircularly emarginate, 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£-4i mm. (c? ? .) 



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

 Fry: <J ? ). 



Three males and two females. This insect resembles the 

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