NEW L0NG1C0RN BEETLES. 
UROCALYMMA, Wcstw. 
Corpus gracile depressum punctatum. Caput antice perpcndicularitcr deflexum (fig 3 a). 
Antennae gracillimsc. Prothorax subquadratus antice ct postice margiuatus, lateribusdente 
parvo in medio armatis. Elytra elongata depressa, subparallela apicem versus attenuata et 
in in caudas duas longas producta, apicibusin ^ hiantibus et acuminatis. Pedes longi 
tenues prsesertim antici maris, qui longissimi sunt, tibiisque anticis ante apicem inhocsexu 
intus, 4 que posticis extus tenuissime penicillatis. Palpi graciles breves (fig. 3 b Maxillae 
et labium). 
Tlie singular insects composing this genus exhibit several 
characters belonging to very different groups of Longicorn beetles. 
The elongated fore legs are analogous to those of Acrocinus longi- 
manus, although in their delicate structure they more nearlyresemble 
those of Gerania Boscii; in the last-named insect, however, all the 
legs are elongated. 
In having the tips of the elytra produced into two long tails in the 
supposed male, these insects are analogous to Cercoptera Banoni, 
Spin . (in Guer. Mag. Zool. Ins. 1839, pi. 12); and to the male of 
Enicodes Fichtelii, Schreib. (in Linn. Trans., and Griff. Anim. King. 
Ins. pi. 65, f. 1, and pi. 73, f. 2*) ; but in both these insects the 
thorax has not the sides armed with a spine, whence I consider 
that Urocalymma has a* nearer relation to Tmesisternus. 
Urocalymma longimana , Westw. (PI. 15, f. 3, male ; f. <j>, female). Fusco-nigricans, 
luteo sericans, punctata, elytris punctato-striatis, basi irregulariter punctatis, guttis 10 
minutis albido-sericantibus adspersis ornatis (2bus posticis in $ obliterate.) Long, 
corp. £ lin. 14, $ lin. 10. 
The remarkable orchidaceous plant represented in the plate is 
the Cirrhopetalon Thouarsii (Bot. Reg. vol. xxiv. p. 11), a native 
of Java, Manilla, the Society Islands, &c. 
* Hitherto the male of Enicodes Fichtelii (plate 15, fig. 4 £.) has alone been figured and 
described. The Rev. F. AY. Hope, however, possesses the other sex, which he obtained from 
the Haworthian collection, in which it was ticketed <c Ind. or . 99 although New Holland is the 
recorded country of the rare species in question. The female is accordingly now figured for 
the first time, plate 15, fig. 4 . It agrees with the male in its colours, but the sides of the 
head are much less produced, and the elytra are not elongated into a pair of tails, although 
they terminate acutely.
