HYAS (p. 30). 
Hyas angularis (p. 30). | 
Leconte [Synopsis of the Lampyride of the United States, p. 33| has proposed a 
genus, Tenaspis, for this species on account of the antenne being simple in both sexes, 
and (as he says) the “light organs” being wanting. In the specimens from Guatemala 
the abdomen is entirely black, as in my type; in the specimens from Mexico, from 
Sallé’s collection, on the other hand, the apical segments are pale, and in one instance 
the whole ventral side of the abdomen is yellow, and all these specimens are smaller, 
and sometimes have the thorax wholly pale. They may therefore be specifically different, 
but the character is not generic. Hyas angularis of the type-form occurs, according to 
Leconte, in the United States, in Texas, and Northern Mexico. 
Hyas semifusca (p. 31). 
To the localities given, add :—GUATEMALA, San Isidro (Champion) ; Panama, Bugaba, 
Volcan de Chiriqui (Champion). 
Var. Elytris totis ochraceis. 
Hab. Panama, Volcan de Chiriqui, Bugaba (Champion). 
About a dozen specimens of a small Hyas wholly ochraceous above occurred in 
Chiriqui, but they do not differ in any important respect from the dark A. semifusca, 
and are of both sexes. Two specimens intermediate in colour of the elytra were also 
found, one in the low country at Bugaba, one at the higher altitude. 
PHANOLIS (p. 31). 
Phenolis ustulatus (p. 32). 
To the localities given, add :—Mexico, Almolonga (Hoge), Cordova (flohr) ; 
GuatemaLA, Mirandilla (Champion). 
Two specimens sent me by Sefior Flohr from Mexico have the disc of the thorax with 
a blackish horse-shoe shaped mark, as the single specimen from Almolonga has also, 
with the scutellum black. 
Phenolis ochraceus (p. 32). 
To the localities given, add:—Guarema.a, Cubilguitz, San Juan in Vera Paz; 
Panama, Bugaba, Volcan de Chiriqui (Champion). 
Mr. Champion remarks that this insect is frequently taken on the wing in dark parts 
of the forest in the daytime.
