Lyppa. Rostrum brevius. Antenne breves. Alz anticee, valdé elongate, 
apice rotundate, directione venarum anomalad; regione venee medianze 
minima, aut potids ejus rami in venz postcostalis ramos transformati. 
The type of this subgenus is Derbe elongata, Fab., from New 
Holland, in the cabinet of the Linnean Society. 
Zevuema. Rostrum ultra basin pedum posticorum extensum. Antenne 
rotundatz. Ocelli obsoleti? Prothorax lateribus concavo-dilatatis pro 
antennis recipientibus. Alze anticz oblongo ovate, apice subtruncate, 
venis numerosis longitudinalibus; vend postcostali ramos 8 posticé, 
mediana tanttim tres emittente. 
This subgenus appears intermediate between Derbe and Thracia 
on the one hand, and Mysidia on the other. The only species is— 
Z. vitiata, fulva; alis anticis flavidis vitté laté media fusca apicem 
versus deflexa alteraque postica parallelA apice vitté abbreviata fas- 
cidque tenui transversd fuscis. Expans. alar. lin. In Mus. Soc. Linn. 
Turacra. Rostrum pectore Iongius. Antenne capite feré duplo longi- 
ores. Oculiorbiculati. Ocelli nulli? Ale antice longissime, anguste, 
apice truncate, venis 12 longitudinalibus inter angulum apicalem et 
analem. 
This subgenus is proposed for the two African species, D. sinuosa 
and D. nervesa, described by Boheman, and considered by him as 
constituting the first section of the genus. Notwithstanding the 
difference of its geographical range, the author adds the following 
fine species from Java, which agrees with the other two in all the 
sub-generic characters 
T. javanica, fulva; pice obscuriore vittd centrali pallidiori, alis 
pallidé hyalinis anticis fascia lata costali fused. Expans. alar. lin. 
Java. D.Horsfield. In Mus. Soc. Mercat. Ind. 
Puenice. Rostrum pectore vix longius. Antenne capite manifesté bre- 
viores. Oculi oblongi, vel obovati, distincté emarginati. Ocelli di- 
stincti. Ale anticee quam in Thracia breviores, apice subrotundate, 
venis feré ut in Mysidid dispositis, 12 longitudinalibus inter angulum 
apicalem et regionem analem. 
This subgenus is proposed for the three African species D. fritillaris. 
fasciolata, and stellulata, described by Boheman, and forming his 
second section of Derbe. 
After reviewing the characters of the preceding subgenera, the 
author expresses the opinion that Otiocerus (including Hypnis, 
Burm.) and Anotia of Kirby, must also be considered as subgenera 
of equal rank with the preceding; that Anotia coccinea, Guér. Icon. 
R. An. MS. pl. 58, f. 3, forms another subgenus; and that the two 
following groups also constitute two other subgenera of Derbe : 
Parara. Rostrum ad basin pedum posticorum extensum. Oculi maximi, 
subtus emarginati. Oculi obsoleti. Antennz maximeze, compressz, 
verrucose, apice subtruncato et setigero. Ale antice longitudine 
mediocres, apice rotundatz, venis paucis cellulisque tribus discoidali- 
bus. 
P. guttata, capite thoraceque fulvis, alis anticis griseo-fuscis margine albo- 
guttatis. Expans. alar. lin. Insula Sti Vincent. D. Guilding. Mus.
