Probably a variety of the cosmopolitan P. galactinus, Fieb., a species also occurring 
in North America; but differing from it in having the cuneus more or less infuscate, 
and in some specimens the embolium also. 
3. Piezostethus albonotatus, n. sp. (Tab. XIX. figg. 10, ¢; 10a, anterior 
leg, 3.) 
Short and rather broad, clothed with a very fine scattered pallid pubescence and also with widely scattered 
long erect hairs; shining, the apical half of the scutellum, the clavus and corium, and the basal half of the 
embolium, opaque; black, the embolium more or less ochreous in its basal half, the corium nigro-fuscous 
or fuscous, with a subquadrate transverse whitish patch about the middle, the membrane in great part 
fuscous; the apical joint of the rostrum testaceous; the antenuze and legs black or piceous, the tarsi 
obscure testaceous; the mesosternum piceous. Head broader than long, smooth, the eyes large; rostrum 
reaching almost as far as the intermediate coxe; antenne with joints 1 and 2 moderately thickencd, 
2 becoming stouter towards the apex, 3 and 4 more slender, 2 longer than 3 or 4, the latter subequal in 
length and clothed with long and short hairs. Pronotum short, convex, narrowing from the base 
forwards, and with the sides rounded in front, the latter obsoletely margined ; the surface almost smooth, 
the posterior lobe transversely rugulose on the disc. Scutellum rugulose at the apex. LElytra almost 
smooth. Orifice of the metastethium transverse, short. Legs short. 
3g. Anterior femora moderately incrassate; anterior trochanters armed with a short tooth. 
Length 13-2 millim. (¢ 2.) 
Hab. Guatemata, El Tumbador, Las Mercedes, Pantaleon, Zapote (Champion) ; 
Panama, Bugaba, Tolé (Champion). 
Twelve examples. This and the following species bear some resemblance to the 
European P. obliquus, Costa, but differ from it in having the clavus, corium, and apical 
half of the scutellum opaque, the third and fourth antennal joints a little stouter, the 
eyes larger, the orifice of the metastethium transverse, &c. The wings have the hamus 
issuing beyond the decurrent nervure. 
4, Piezostethus bimaculatus, n. sp. (Tab. XIX. fig. 11.) 
Very like P. albonotatus, but with the whitish mark on the corium oblique and placed much nearer the base, 
the tibie, except at the extreme base, and the tarsi ochreous; the pronotum distinctly sinuate at the 
sides; the membrane becoming hyaline towards the outer margin; the orifice of the metastethium a little 
longer and slightly curving forwards externally. 
Length 13 millim. ( 9.)
