74 HEMIPTERA-HOMOPTERA. 
8. Mysidia delicatissima, sp.n. (Tab. VIII. figg. 23, 23 a.) 
Parva, lacteo-albida, nitidula, fere unicolor; capite perbrevi, vix ante oculos producto, fronte perangusta ; 
tegminibus modice elongatis ; pedibus testaceis. 
A small, semitransparent, somewhat shining, white species, with some of the veins faintly darker at places, 
and with a minute spot on the interior margin towards the base; head very short, scarcely produced 
before the eyes ; tegmina comparatively shorter than in many of the species of the genus, broadest a little 
beyond the middle ; legs testaceous. . 
Long. 7-73 millim.; lat. ad hum. 1 millim.; exp. tegm. 14 millim. 
Hab. Mexico, Teapa in Tabasco (H. H. Smith). 
9. Mysidia(?) spreta, sp. n. 
Flavescens, unicolor, abdomine supra nigro-vittato; capite parvo, excavato, antice truncato, oculis nigris ; 
antennis perbrevibus ; scutello magno, sat indistincte carinato ; tegminibus concoloribus ; pedibus testaceis. 
Of a uniform flavescent colour, with the eyes, edges of front, and bands on the upperside of the abdomen 
dark; head small, truncate in front, antenne very short ; pronotum narrow, considerably dilated at the 
sides ; scutellum large, with the central carina fairly distinct and with traces of other carine at the sides; 
tegmina rather small and shining ; legs testaceous. 
Long. 8 millim.; lat. ad hum. 13 millim.; exp. tegm. 15 millim. 
Hab. Mexico, Teapa in Tabasco (H. H. Smith). 
This species has very short and thick antenne, and in this respect may be classed 
with Mysidia; but the venation of the tegmina appears to be quite different, and I 
have no doubt that, when more specimens have been discovered, it will have to be 
placed in a separate genus. 
OTIOCERUS. 
Otiocerus, Kirby, Trans. Linn. Soc. xiii. p. 16 (1821) ; Westwood, Trans. Linn. Soc. xix. p. 12. 
Cobazx, Germar, Mag. Ent. iv. p. 1 (1821). 
Hynnis, Burmeister, Handb. Ent. ii. 1, p. 154 (1835). 
The members of this genus are in most cases distinguished by the extraordinary 
development of the second joint of the antenne, which appears, in fact, to consist of 
two long and more or less curled joints proceeding from a very short and thick first 
joint ; in O. degeeri, however, the female has the second joint very short, as short as in 
Mysidia, but bilobed, and in our collection there is a species (which I have doubtfully 
referred to the genus) in which the second joint is short and simple. Burmeister 
described O. degeeri as distinct from Otiocerus under the name of Hynnis rosea, on 
account of the angle of the fore wings being dilated into an angular projection ; this is 
evidently, however, not a generic character, and the venation of the wings is the same 
as that of O. coquebert, in which the dilatation is not evident. 
1. Oticcerus montanus, sp.n. (Tab. VIII. figg. 24, 24 a.) 
Rufescens ; capite prelongo, supra viso albo-marginato, antennis robustis, rufis; pronoto brevissimo ; scutello 
magno, medio late albido, lateribus rufescentibus ; tegminibus vitreis, venis latis, roseis ; alis albidis ; 
abdomine ad medium albido-testaceo ; pedibus albidis ; stylis maris longis, tenuibus.
