In the Museum collection there are four specimens of 

 an insect which I believe to be Telephorus adultus, Cas- 

 telnau (N. Hist. Anim. Art. I. p. 271), which nearly agree 

 with variety 2 in coloration, but differ in having the 

 antennae shorter and very slender ; the abdominal segments 

 are bordered with yellow, and the elytra are not pubescent 

 but strongly and closely punctured. 



Chauliognathus heros, Guerin, var. 



Elongatus, niger, opacus; thorace flavo, medio gutta 

 nigra notato ; abdomine ferrugineo, segmentis P et 2° ad 

 latcra gutta nigra uotatis, segmentis 3° et 4" nigris. 



Long. 10 lin. 



This variety differs from the ordinary form of C. heros, 

 Guerin (Rev. Zool. 1843, p. 18), in having the elytra 

 entirely black instead of yellow at the base. 



A second specimen of the ordinary form received with 

 the above has the abdomen ferruginous, with four black 

 spots on each side. 



Hab. — Ecuador (Buckley).
