270 ORTHOPTERA. 



Tegmina more than half the length of the abdomen, the costal margin smoky-hyaline and narrowly 

 devoid of veins, the apex rounded. Wings somewhat infuscated, as long as the tegmina. Hind femora 

 only moderately robust, their greatest breadth about one-fifth of their length ; the genicular lobes 

 acuminate ; hind tibiae rather strongly hirsute and provided externally with seven spines ; hind tarsi 

 with the second joint four-fifths the length of the first. Cerci without any definite subapical teeth below, 

 but somewhat undulate. 



Colour as described above, the additional detail as follows : — Antennas basally greenish, gradually becoming 

 darker apically, where they are brown, without annulation. Abdomen greenish-testaceous ; last dorsal 

 and posterior half of preceding segment, as well as the apical portion of two or three of the terminal 

 ventral segments and the border of the supra-anal plate and the tips of the cerci, strongly infuscated or 

 black. Hind tibia? olivaceous, the spines black. 

 2 . Fastigium of the vertex only gently depressed, narrowly sulcate ; antennae with the median joints 

 narrowly annulate with flavous at their points of articulation, basally green, the apical joint pale. Gense 

 of hind femora ferruginous. Median carina of pronotum plain throughout, most prominent on the 

 anterior lobe back of the " collar." Valves of the ovipositor slender, straight, without serration or apical 

 hook. Tegmina as long as the head and pronotum combined, their apices rounded and their dorsal edges 

 just touching. 



Length of body, S 16-5, $ 17*5 ; of pronotum, <$ 3-1, 5 3*75 ; of tegmina, S 7, $ 6-5 ; of hind femora, 

 <$ 10, $ 105 ; of antennae 12*5 millim.

A single female. The insect referred to this species is of the opposite sex from the 

 one described by Stal, but seems to fit in quite well with his characterization, although 

 somewhat faded in colour through immersion in alcohol. Its pronotum is unusually 

 smooth. The valves of the ovipositor are longer and more slender than usual and 

 black-bordered; the sixth and seventh ventral segments are bivittate with black 

 below, and the supra-anal plate and the last dorsal segments are likewise bordered 

 or marked with the same tint. The first and second segments of the hind tarsi are 

 equal in length, while the tibiae are infuscated at the apex. In size it is about equal 

 to the same sex of the preceding species, but the tegmina and wings are somewhat 

 longer, measuring 8*25 mm. The antennae lack the annulation as described for 

 A. viridulus, 2 . 



4. Anniceris olivaceus, Giglio-Tos.

 Hab. Panama, Darien 1 . 



No specimens of this species are at hand, but the description is sufficiently concise 

 to render, its recognition easy.
