[Vol. VIII, No. 8, 
tertio breviore.” Judging from the description Halobatopsis 
Begini Ashm. belongs to a new genus. 
Trepobates pictus is not recorded from Central America in the 
“Biologia” but it was recorded from Tamaulipas, Mexico, by 
Uhler in 1884, and is distributed southwards at least to Venezuela 
from where I have winged specimens. 
Telmatometra Bergr., n. gen. 
Body about two and one-half times longer than broad. Head 
subtriangular, much broader than long, rounded in front, ante- 
ocular part much shorter than the eye; seen in profile the apex 
of the head is subangularly rounded and distinctly projecting 
beyond the base of the rostrum ; eyes prolonged backward beyond 
the basal margin of the head by nearly one-fourth their length, 
the prolonged part touching the lateral margins of the pro- 
thorax, the upper inner margin of the eyes rounded; the parallel¬ 
sided, at the base somewhat dilated clypeus not visible from 
above, bent back towards the underside of the head, giving the 
head a somewhat “ homopterous ” appearance when seen in pro¬ 
file; labrum almost reaching the apex of the first rostral joint; 
rostrum extending considerably beyond the anterior margin 
of the mesosternum but not reaching its middle; second joint 
very short, ring-like, third joint long; antennae inserted immedia¬ 
tely before the eyes a little above the level of their lower margin, 
long and thin, in the female distinctly passing the base of the ven¬ 
ter, in the male (owing to the shorter abdomen) almost reaching 
the tip of the abdomen, third joint longest, even longer than the 
basal joint and more than twice as long as the second joint, fouith 
joint almost twice the length of the second, the two basal joints 
a little thicker than the two thread-like apical joints. Thorax 
widening from the apex to the middle acetabula, sides very slight¬ 
ly rounded, more distinctly so towards the apex. Pronotum in 
the winged form extending backwards over the mesonotum, v i- 
dening from the apex to the humeral angles, then gradually 
tapering to the rather narrowly rounded end, the apical margin 
straight between the eyes. Mesosternum convex without rostral 
furrow, broadly arcuately sinuate posteriorly. Mesopleurae bent 
over to the dorsal side of the thorax, a narrow posteriorly broad¬ 
ening part of them being visible from above. Metasternum very 
short, of the same size and appearance as the first ventral seg¬ 
ment, orificium not visible, apparently hidden under the posterior 
margin of the mesosternum. Metapleurae visible only from 
above, separated from the dorsal part of the mesopleurae by a 
deep oblique suture. Hemelytra complete in the vinged form, 
membrane well separated from corium except at the inner part 
where it is subconfluent with the endocorium and the claval area; 
corium with the subcostal vein usually obliterated towards the
