ATHEAS. 45 
1. Atheas flavipes, n. sp. (Tab. III. figg. 19; 194, part of the body beneath.) 
Narrow, black, in fresh specimens covered with a bluish-white waxy secretion; the pronotal carine pale, the 
membranous margins of the pronotum and elytra whitish-hyaline, the elytra with the nervures beyond 
the discoidal area usually fuscous or brownish; the antenne black, the third joint sometimes flavous ; 
the legs flavo-testaceous or flavous, the tarsi infuscate at the tip. Head dull, rugulose, the antenniferous 
tubercles slender, acute, and moderately long; antenne long and very slender, joint 1 twice as long as 2, 
3 nearly twice as long as 4, 4 about twice the length of 1. Pronotum finely tricarinate, closely punc- 
tured ; the membranous margins rather wide, straight, and converging forwards. rounded behind, with a 
row of rather large areole and a narrow, elongate, hyaline space towards the apex on the inner side; the 
posterior portion obtuse at the tip. LElytra elongate, subparallel at the middle in some specimens ; 
discoidal area extending to about the middle; subcostal area biseriate ; costal and sutural areas (the basal 
portion of the latter excepted) rather widely and subequally reticulated, the costal area triseriate in the 
widest part, biseriate in front. Mesosternal lamine parallel, rather widely separated. 
Length 21-23, breadth 1-1,4, millim. (d Q.-) 
Hab. Panama, Bugaba (Champion). 
Thirteen specimens. Differs from the following species in the longer and more acute 
antenniferous tubercles, the longer and more slender antenne, the broader membranous 
margins of the pronotum, and the wider reticulation of the costal and sutural areas of 
the elytra. In immature examples the pronotum and elytra are fuscous. The antenne 
in eight of the specimens have the third joint flavous. 
2. Atheas fuscipes, n. sp. (Tab. III. fig. 20.) 
Narrow, black, in fresh specimens covered with a bluish-white waxy secretion, the pronotum with the carinz 
and the tip of the posterior process usually pale, the membranous margins of the pronotum and elytra 
whitish-hyaline, the elytra with the nervures of the sutural area and apex black or fuscous; the legs 
fusco-testaceous with the tarsi black, or black with the knees and the apical halves of the tibie testaceous. 
Head dull, rugulose, the antenniferous tubercles short and pointed; antenne extending to considerably 
beyond the base of the elytra, moderately slender, joint 1 nearly twice as long as 2, 3 about twice as long 
as 4, 4 a little longer than 1 and 2 united. Pronotum feebly tricarinate, the outer carine indistinct at 
the middle, closely punctured ; the membranous margins narrow, straight, and converging forwards, 
rounded behind, with a row of small areole. Elytra long, slightly rounded at the sides; discoidal 
area extending to beyond the middle; subcostal area bi- or triseriate; costal area biseriate, in some 
specimens ( ? ) triseriate in the widest part. Mesosternal lamin parallel. 
Length 24-23, breadth 4-1 millim. (¢ 9.) 
Hab. Mexico, Cordova (Bilimek, in Mus. Vind. Ces.), Teapa in Tabasco (H. H. Smith) ; 
GUATEMALA, Chiacam and San Gerénimo in Vera Paz, Rio Naranjo (Champion). 
Fourteen specimens, two only of which are from Mexico. Differs from the following, 
A. nigricornis, in the more feebly carinate pronotum, the slightly longer antenne, the 
parallel mesosternal lamine, and darker legs. ‘The costal area is sometimes triseriate in 
the widest part in the females. An example from Rio Naranjo is figured. 
3. Atheas nigricornis, n. sp. (Tab. III. fig. 21.) _ 
Very narrow, black, the pronotal carine whitish, the elytra and the triangular posterior portion of the 
pronotum varying in colour from fuscous to pale testaceous, the membranous margins of the pronotum 
and elytra whitish-hyaline, the nervures at the apex and in the sutural area brownish or fuscous ; the
