Another paratype, also a brachypterous female from Richfield, 
- Utah, August 24 (Ball), is a little more robust, and has tips of 
the clavi, about six macule on either costa, and scattered dots 
on the principal veins and on thorax, black. 
Piesma ceramica, n. sp. 
Thorax and antenna as indicated in key; thoracic carine very 
distinct, more or less tortuous, the pair of lateral carinz espe- 
cially being longer and more conspicuous than in preceding 
forms; a pair of intercalated short carinze just back of callosities. 
A brachypterous species, pale stramineous in color, with only 
traces of light brown spots along costal margins and on callosi- 
ties, eyes reddish. Elytra slightly surpassing abdomen, the 
divisions solidly fused, sometimes slightly incurved and over- 
lapping at tip, sometimes not. Whole: dorsal surface closely 
punctate; the distinct sculpturing and pale color suggést a awax 
counterfeit fresh from the mould, rather than a real infect. 
Areolar formula, see table, page —. Length 3 mm. 
Described from three females, labelled Courthouse, U., 8-10-06 
(Ua) Na Me). 
Piesma rugulosa, n. sp. 
A species much like the above in structure of antenne and 
thorax including the carinz, but smaller, less closely punctured, 
and spotted. 
Elytra distinctly brown spotted ; about nine spots on each costal 
margin, scattered spots on corium and claval area of the fused 
elytron, and a few indistinct spots on posterior part of thorax; 
venter with five series of brown spots; eyes pale. Areolar 
formula, see table, page 92. Length 2.5 mm. 
Type a brachypterous male, from Rocky Ford, Colo., April 18, 
IQII, on greasewood, H. O. Marsh (U.S. N. M.). 
Piesma protea, n. sp. 
Structure of antenna and thorax as noted in key; carinze much 
reduced, the median pair only being obvious, lateral almost obso- 
lete, central and intercalated lacking. 
Color pale stramineous to pale fuscous, the membranous por-
