tertio breviore." Judging from the description Halobatopsis 

 Begini Ashni. belongs to a new genus. 



Trepohates picHis 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 timfes longer than broad. Head 

 subtriangular, much broader than long, rounded in front, ante- 

 ocular part much shorter than the 63-6 ; 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, fourth 

 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, ^ 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 winged form, 

 membrane well separated from corium except at the inner part 

 where it is subconfiuent with the endocorium and the claval area ; 

 corium with the subcostal vein usually obliterated towards the
