Stenomacra cliens (p. 226). 
Stenomacra sallei, Fallou, Rev. d’Entomol. x. p. 8. 
M. Fallou has kindly forwarded me a Mexican specimen which he had described as 
a new species under the name of S. sad/et; but this proves to be identical with S. cliens, 
Stal, as also recently observed by Dr. Bergroth (Rev. d’Entomol. xi. p. 262). 
PHLAAX, gen. nov. (To precede the genus Arhaphe, p. 226.) 
Head very broad, immersed to the posterior margins of the eyes, obscurely angulated anteriorly. Antenne inserted 
at nearer apex of head than eyes; basal joint incrassated, about or scarcely reaching apex of head, second 
joint longest, its apex slightly incrassated, third Joint more or less distinctly incrassated at apex, and shorter 
than the fourth, which is thickened. Pronotum long, very strongly constricted at about centre, the anterior 
lobe moderately globose, the posterior lobe angularly depressed from its disk to the median constriction : 
anterior lobe sublevigate, excepting near anterior margin, posterior lobe thickly and coarsely punctate. 
Scutellum somewhat centrally gibbous. Abdomen and corium very strongly concavely sinuate to a little 
beyond centre, where they are widened, and the abdomen is convexly rounded to apex ; the membrane docs 
not cover the lateral abdominal margins. The anterior femora are very strongly incrassated, and have one or 
two long spines beneath near apex ; the posterior legs are long. Rostrum with the basal joint not quite 
reaching the latitude of the eyes, second joint slightly passing the base of the head, apical joint reaching 
or slightly passing the anterior coxe, second and fourth joints about subequal in length, and a little 
longer than the third joint. Ocelli absent. 
I place this remarkable genus near Arhaphe, with which, however, it has little in 
common. 
1. Pheeax formicarius, n.sp. (Tab. XXXVI. fig. 6.) 
Black ; corium with a greyish-white spot at about centre of lateral margin and another at the apex, these spots 
being margined with intense black, a pale spot on connexivum near apex of corium. Antenne with the 
apex of the first joint and the base of the second pale ochraceous ; intermediate and posterior femora annu- 
lated with greyish-white near base; tarsi ochraceous. 
Long. 52 millim. 
Hab. Panama, Volcan de Chiriqui 2500 to 6000 feet (Champion). 
Four examples. 
2. Pheax balteatus, n. sp. (Tab. XXXVI. fig. 7.) 
Allied to the preceding species, P. formicarius, but smaller, and with the first and second joints of the antenne 
(excluding apex of second) ochraceous ; anterior femora and tibiz brownish-oehraceous, basal annulation 
to intermediate and posterior femora small, obscure, and ochraceous, pale spots to corium smaller and 
more obscure, and with a transverse greyish-white fascia across the base of the membrane. The anterior 
lobe of the pronotum is also less punctate at its anterior margin. 
Long. 4 millim. 
Hab. Panama, Bugaba (Champion). 
Two examples.
