34 MALACODERMATA. 
and legs are black; only the fifth segment has a small white spot; and even this is 
apparent in one alone of the three specimens which have been sent. 
MEGALOPHTHALMUS. 
Megalophthalmus, Gray, Griffith’s An. Kingd. Ins. 1. p. 871 (1882). 
The separation of this genus from others with strongly pectinate antenne, small eyes, 
and with a very small portion of the abdomen luminous, on the ground of the head 
being scarcely covered by the very short pronotum, is unnatural. In the Central- 
American species even this character is not maintained. 
The females of this genus seem unknown, so that its position is still provisional; but 
I think that it is best placed in this subfamily. . 
Four species of Megalophthalmus have been described from South America. The 
genus is also said, but incorrectly, to be found in Chili. 
1. Megalophthalmus guatemale. 
Megalophthalmus guatemale, Gorh. Trans. Ent. Soc. 1880, p. 98°. 
Hab. Mexico, Cordova (Sallé); Guatema.a, Zapote (Champion }). 
2. Megalophthalmus godmani. 
Niger, prothorace, coxis et femoribus intermediis basi elytrisque ferrugineis, abdominis segmento quinto 
(maris?) apice albo; elytris tricostatis ; antennis late pectinatis. Long. 8-9 millim. ¢? 
Hab. GuateMaa, Cubilguitz (Champion). 
Rather larger than IZ. guatemale, and with the antenne a little more widely pecti- 
nate, but otherwise resembling it in form. The second and third coste are not so 
evidently united at the apex; and the apical branch is only just visible. 
LUCIDOTA. 
Lucidota, Castelnau, Ann. Soc. Ent. Fr. i. p. 186 (1833). 
This genus is not well defined at present; two types of species are included in it, as 
will be seen by reference to my figures of the ventral apical segments of the males 
(Trans. Ent. Soc. 1880, pl. i. figs. 8, 10,11). The first division consists of species, 
often of large size, from Tropical South America. The second division are more mode- 
rate in size; but both agree in having the antenne pectinate or serrate, often long, the 
prothorax usually short and its disk channelled, and the abdomen not lobed. 
LIucidota is distributed in America from Chili to the United States, and is even 
represented in Japan. |
