104 EEOTYLIM. 



Two specimens, which I refer with some doubt to this species, only differ from 

 examples in Crotch's collection in the central and lateral black spots on the elytra 

 being united and forming a broad fascia, indented on the basal side. In form they 

 agree precisely with others from South America ; but they are rather larger than the 

 average. Considerable doubt exists as to what species should be referred to the Chryso- 

 mela gibbosa of Linnaeus ; the description, however, agrees with the form here recorded. 

 The example figured is from Chontales. 



4. Cypherotylus elevatus. (Tab. VI. figg. 4, 4 «, var.)

 Cypherotylus elevatus, Crotch, Cist. Ent. i. p. 538 2 . 



Hab. Panama, Caldera in Chiriqui (Champion). — Colombia, Bogota 2 ; Guiana, 

 Cayenne x 2 . 



Var. ? Elytris subalbidis, punctis minus variolosis. 



Hab. Panama, Bugaba (Champion). 

 One specimen only from each locality. 



5. Cypherotylus impressopunctatus. (Tab. VI. fig. 5, s .) 



Cypherotylus impressopunctatus, Crotch, Cist. Ent. i. pp. 148 2 , 540 2 . 



Hab. Nicaragua, Santo Domingo in Chontales (Janson l 2 , Belt) ; Panama, Bugaba, 

 Volcan de Chiriqui (Champion). 



The male has the thorax more convex, and with the sides sinuate, and the base with 

 deeper impressions ; the front tibiae slightly bent inwards close to their apices ; the 

 first two joints of the tarsi wide ; and the basal segment of the abdomen with a patch of 

 black pile in the middle. Many examples *. 



* The following allied species appear to be undescribed : — 



Cypherotylus patellatus. 



Oblongus, niger, elytris alte carinatis, vix gibbosis, testaceis, punctis nigris ad apicem magis confluentibus et 

 in seriebus subdigestis, apice tenuiter nigro. Long. 19-22 millim. 

 Sab. Peru (coll. Oorham). 



Varies in .the amount of black at the apex of the elytra. Distinct from C. stillatus or C. impressopunctatus 

 by the much more acutely keeled ridge of the suture. 



Cypherotylus anthracinus. 



Niger, nitidus, elytris alte carinatis, subgibbosis, punctis magnis variolosis. Long. 20-21 millim. 

 Hab. Peru, Chanchamayo (coll. Oorham). 



This is the only wholly black Cypherotylus known to me. In form it is similar to C. patellatus. Two 

 specimens, apparently both females.
