FIDICINA. 17 
This species exhibits little variation ; and the two specimens described by Walker 
under the above names are identical. The habitats of these were unrecorded. 
4, Fidicina spinicosta. (Tab. II. figg. 15, 15 a, 153.) 
Cicada spinicosta, Walk. List Hom. i. p. 126. 64°. 
Cicada lacrines, Walk. ibid. p. 182.70; Stal, Ofv. Vet.-Ak. Férh. 1862, p. 481. 
Fidicina lacrines, Stal, ibid. p. 485. 
Hab. Costa Rica (Mus. Berol.); Panama (coll. Dist.).—Gvutana, Cayenne (coll. Sign.) ; 
Brazit, Para 1. . 
Walker, under the name of C. spinicosta, subsequently incorporated specimens of his 
other species, C. semilata; and Stal necessarily thus wrote C. lacrines=C. spinicosta 
(“ad partem”). There can, however, be no doubt as to the type, which I have examined 
in the British Museum, and which agrees with the Costa-Rican specimen here figured 
contained in the collection of the Berlin Museum.

Fidicina semilata, Stal, Ofv- Vet.-Ak. Férh. 1862, p. 485. 
Hab. Costa Rica (van Patten; coll. Dist.).—St. Lucta!®; VENEzUELA??; GUIANA, 
Demerara‘, Cayenne !; TrinrpaD (coll. Dist.); Brazit, Para®, Ega (de Mathan; coll. 
Oberthiir). 
This species is not of an exceedingly variable nature, as the above synonymy would 
apparently indicate, but is rather an example of the late Mr. Walker’s treatment of the 
subject. It is allied to /. spenicosta, but differs by the longer and less robust body, the 
more elongate and less tumid face, shape of the opercula, &c. 
6. Fidicina fumea, n. sp. (Tab. IV. figg. 4, 4a, 40.)* 
Q. Head and thorax above olivaceous. Head with the front marked with a central lunate spot, a central 
longitudinal line and the basal margin black ; vertex broadly black between the eyes, which are bronzy ; 
—_ 
* On the preceding page it was stated that five species of Fidicina were enumerated. The present (sixth) 
species was received from Mr. Champion since that statement was printed.
