Compared with a Colombian male of the gorgeously colored 

 Citrina venilia (Westwood) shows, in addition to the features 

 given by Redtenbacher, the following characters, which, com- 

 bined, warrant the generic separation made by that author. 

 In viridipes the head is decidedly longer, the eyes and ocelli 

 smaller and less prominent, the pronotum shorter, the tegmina 

 much longer, the cephalic femora showing distinctly greater 

 thickening and the tarsi, though elongate, decidedly shorter. 



The present species is distinctively colored, the pale green of 

 the median and caudal limbs and of the longitudinal tegminal 

 and wing band contrasting strongly with the light and dark 

 browns of the other portions. 



The specimen here recorded agrees fully with the type except 

 in being somewhat smaller. Length of body, 47; length of head, 

 3.7; length of pronotum, 2.1 ; length of mesonotum, 5.8; length of 

 tegmen, 5.8; length of wing, 30.5; length of caudal femur, 12.8; 

 length of caudal tarsus, 5.8; length of caudal metatarsus, 3.2 mm. 



Brizoides annulicornis new species (Plate XIV, figures 1 and 2.) 



This beautiful light green walking-stick is nearest B. graminea 

 Redtenbacher, described from Bugaba, Panama. It differs in 

 the strikingly annulate antennae, granulose cephalic half of 

 mesonotum, with a few of these granules laterad black but median 

 sulcus immaculate, faint markings of anterior field of wings 

 and limb annuli, shorter tegmina and longer limbs. 



The carinae of the limbs are used largely by Redtenbacher to 

 separate this and the related genera. These features are often 

 more subtle than would be supposed. In the insect here under 

 consideration we would describe the cephalic femora as having 

 the dorsal carinae distinct, the dorso-internal slightly the stronger 

 with the median carina of the ventral surface certainly present 

 but not strongly developed. This would appear to represent 

 a condition intermediate between Brizoides and Chlorophasma 

 as defined l)y Redtenbacher. For the ])resent we can go no 

 further thaji to assign annulicornis to Brizoides, awaiting
