The single specimen of Semiotus furcatiis (Fab.) Lap. (Fig. 1, bj is 

 a remarkable variety, as it is undoubtedly the intermediate between 

 typical furcatiis (Fig. 1, a) which inhabits eastern Amazonas, Vene- 

 zuela, Guiana, etc., and S. bilineatus Cand. (Fig. 1, c) which 

 is indigenous to Colombia. S. fulvicollis Blanch. (Fig. 1, d) is 

 but a variety of furcatiis, separated on the furcation of the marginal 

 black vitta being carried to the tip of the elytron, thereby making 

 a submarginal vitla. In typical furcatus the marginal vitta is 

 furcate to beyond the middle and the thoracic vitta is narrowly 

 fusiform. In S. bilineatus the vitta is completely fused and the 

 thoracic vitta is oval, and covers more than one third of the notum. 

 The specimen in this collection and another similar specimen in my 

 collection, taken at Pebas, Peru, the lateral marginal vittse are 

 similar to those of furcatus but the dorsal vittse are similar to S. 

 bilineatus. 



The series of specimens of Chalcolepidius candezei Dohrn. in- 

 clude two very distinct varieties and one intermediate. The 

 typical form collected at Abuna and Camp 39 has the strial vittse 

 thickly beset with whitish colored scales, and the prothorax and 

 ventral surfaces with bronze purple scales. 



Var. b. collected at R. R. Camps 35, 39, 41, and 43 has the elytral 

 interstrial spaces clothed with metallic green scales and strise 

 beset with deep ferruginous scales, the thorax and ventron clothed 

 with metallic green scales. Var. a. collected at Porto Velho is
