PHATNOMA. 3 
Rostrum extending to far beyond the metasternum ; rostral groove parallel and nearly reaching the last ventral 
suture; buccal lamine prominent, projecting beyond the front of the head, closing the rostral groove 
anteriorly ; antenne moderately long, widely separated, exceedingly slender, with joints 1 and 2 stouter, 
smooth, and short, 3 very elongate, 4 somewhat fusiform at the tip and longer than 1 and 2 united; head 
elongate-triangular, with three stout porrect frontal spines, two slender spines behind and two others in 
front, and slender, spiniform, antenniferous tubercles; pronotum with the base truncate and bisinuate, 
leaving the small scutellum exposed, the submembranous margins acutely dilated at the sides and in front, 
and closely reticulated, the areole more or less hyaline, the disc tricarinate, the outer carine abbreviated 
in front; elytra with well-defined clavus and sutural, discoidal, subcostal, and costal areas, the discoidal 
area limited within and without by a sharply raised carina, each bearing a single row of oblong areole, 
the outer carina extending to the base and the inner one to near the tip, the discoidal and subcostal areas 
with transverse raised lines, the costal area closely reticulated, with three or more rows of small areolz, 
which are more or less hyaline ; wings extending beyond the abdomen; legs slender. 
In the allied genus Cantacader (= Taphrostethus, Fieb.) the pronotum is produced 
behind so as to completely cover the scutellum, and has five carine, and the elytra 
have an indistinctly defined clavus and a well-defined subcostal nervure, of which latter 
there is no trace in Phatnoma. 
Pronotum with more or less broadly dilated margins, the outer carinz on the 
disc parallel or subparallel; elytra suboval, the costal area extending 
broadly to the apex, without a series of larger areolz along the margin. 
Pronotal margins broad ; costal area with four rows of areolz at the middle. marmorata, n. sp. 
Pronotal margins very broad, extending obliquely forwards ; costal area with 
five rows of areole at the middle . . . .. .. . =. +=. +. +. annulipes, n. sp. 
Pronotum with moderately dilated margins, the outer carine curving inwards ; 
elytra regularly oval, the costal area narrowing towards the apex, with 
a series of oblong larger areole along the margin . . . . . . . . ovata, n. sp. 
1. Phatnoma marmorata, n. sp. (Tab. I. figg. 1; la, the body beneath, ¢ .) 
Brownish-ochreous or sepia-brown, mottled with fuscous, the fuscous markings on the costal area of the elytra 
forming numerous vague transverse fasciz, which sometimes terminate in a smail black spot on the costal 
and inner margins, the apex of the clavus and some spots on the carine also black; the pronotal and 
elytral margins partly hyaline; the antenne testaceous, with the apical joint partly or entirely black, the 
third joint sometimes infuscate ; the legs testaceous, with the knees usually infuscate, the femora with a 
yellow annulus before the apex. Pronotum with the margins raised, and broadly, acutely dilated before 
the middle as well as in front, becoming narrow behind, the anterior dilatation terminating in a rather 
long slender spine ; the disc closely punctured and tricarinate, the outer caring subparallel. Elytra mode- 
rately broad, suboval, broadly rounded at the apex; discoidal and subcostal areas equal in width, separated 
_ by asharply raised carina, which extends forwards to the base, the discoidal area open behind and limited 
inwards by a curved carina which extends to near the tip of the elytra; the clavus and the sutural, 
discoidal, and subcostal areas with very small rounded punctiform areole, the discoidal and subcostal areas 
each with about five transverse or oblique pallid raised lines; costal area rather broad throughout, closely 
reticulated, there being four rows of areole at the middle, increasing to five or six behind. 
Length 34-4, breadth 2 millim.
