TETTIGIA.—PROARNA. __ 11 
as long as broad. The species belonging to this genus are apparently not numerous, 
but somewhat widely distributed. It includes 7. orni (Linn.), a well-known European 
insect, and is represented in Africa, Madagascar, Australia, and the Nearctic Region. 
Two species are here enumerated as found in this fauna. 
1. Tettigia hieroglyphica. (Tab. III. figg. 2, 2 a, 2d.) 
Cicada hieroglyphica, Say, Complet. Writ. ii. p. 371. 1’. 
Cicada johannis, Walk. List Hom. i. p. 149. 877. 
Cicada sex-guttata, Walk. List Hom. i. p. 154. 93. 
Hab. Nortu America, Pennsylvania, New Jersey 1, Florida ?.—Muxico (Mus. Berol.) 
The figure is that of a Mexican specimen in the Berlin Museum, which not only 
agrees with Say’s description, but also with some typical North-American specimens in 
the British Museum, which have probably been received under Say’s name. — 
2. Tettigia pennata, n. sp. (Tab. IL. figg. 12, 12a, 126.) 
2. Head, pronotum, and mesonotum greenish. Head with the frontal marginal angles, a transverse streak 
on lateral margins, inner margin of eyes, and area of the ocelli black; ocelli red. Mesonotum with a 
central longitudinal suboblong spot, rounded posteriorly and angulated anteriorly, on each side of this a 
short oblique streak behind eyes, and a D-shaped spot near each lateral margin black. Mesonotum with 
four large, central, and somewhat irregular black-bordered obconical spots, a black spot on each lateral 
margin, and two small spots of the same colour in front of the basal cruciform elevation. Abdomen 
above dull testaceous, with the basal angles and-anal appendage greenish, somewhat thickly clothed with 
white pile. Body beneath greenish ; transverse strive to face, bases and apices of cox, apex of rostrum, 
segmental incisures, and inner margins of anal appendage black. Legs greenish, apices of femora black, 
apices of tibiee and tarsi dull testaceous, tarsal claws black. Tegmina pale hyaline. Neuration of basal 
half greenish, remainder fuscous; base of first ulnar area, transverse vein at base of second ulnar area, a 
central spot on the longitudinal vein enclosing third ulnar area, and transverse vein at base of eighth 
apical area, and claval margin black; a prominent white opaque spot at base of first ulmar area. Ana- 
stomoses, and a submarginal row of spots situated on veins, pale fuscous. Wings pale hyaline; veins 
fuscous, with some of the discal ones greenish. . 
The face is globose, strongly and transversely striate, with a central longitudinal sulcation ; rostrum reaching 
the posterior coxe ; head small, with the eyes very globose, and much narrower than base of pronotum. 
Long. 17 millim., exp. of tegm. 66 millim. 
Hab. GuatEMALA, Senahu (Champion). 
One female specimen has been received from Mr. Champion, the male being at 
present unknown to me. : 
PROARNA.. 
Proarna, Stal, Stett. ent. Zeit. xxv. p. 61 (1864) ; Hem. Afr. iv. p. 7 (1866). 
This genus is easily separated from the two preceding by the character of having the 
transverse vein at the base of the second apical area frequently curved, and never or 
very slightly oblique. According to present knowledge the genus is confined to the 
Neotropical and Nearctic Regions, and, in comparison with the total number of described 
species, is well represented in Central America.
