5 (a). Arocera altivola, n. sp. (Tab. XXXI. fig. 18.) 
Allied to A. affinis, Dist., but with different surface-markings, which consist of small black rounded spots, 
situate two on disk of pronotum, one at each basal angle of the scutellum, two before the apex of 
scutellum, which is also black, and one on the disk of each corium; a large black spot on the margin 
of the corium, parallel with the smaller discal spot. This species also differs by having the lateral lobes 
of the head distinctly longer than the central lobe. 
Long. 12 millim. 
Hab. Panama, Volcan de Chiriqui 4000 feet (Champion). 
A single specimen was taken by Mr. Champion. 
5(s). Arocera chiriquensis, n. sp. (Tab. XXX. fig. 19.) 
Reddish-ochraceous ; margins and base of head, antenne, and eyes black; pronotum with the anterior and 
lateral margins, a rounded spot at each posterior lateral angle, and two large discal spots resting on 
posterior margin more or less black; scutellum with two large spots at base and two large spots near 
apex more or less black; corium with irregular black markings; membrane black, the apex greyish- 
white. Body beneath reddish-ochraceous, sternal and abdominal segmental margins black ; legs reddish, 
much suffused with black ; rostrum pitchy. The body is somewhat short and broad; antenne with the 
second joint slightly shorter than the third, which is also a little shorter than the fourth, fourth and fifth 
almost subequal in length, or the fourth a little longer than the fifth. 
Long. 10 millim. 
Hab. Panama, Volcan de Chiriqui 2000 to 4000 feet (Champion). 
6(a). Arocera jalapensis, n. sp. (Tab. XXX. fig. 18.) 
Prasinous ; base of head, eyes, antenne, three discal spots and two near anterior margin of pronotum, two 
large spots at base of scutellum and two contiguous, near apex of same, a broad irregular transverse 
fascia to corium, and the membrane (excluding apex) black. Body beneath ochraceous ; rostrum, legs, 
sternum, a double series of spots on lateral margins, and a central series of transverse spots to abdomen, 
black. (Antennee mutilated.) 
Long. 12 millim. 
Hab. Mexico, Jalapa (M. Trujillo). 
Allied to A. patibulata, Dist., from Costa Rica, and possibly a varietal form of that 
species; but the colour-markings are very distinct, and the difficulties in the study of 
the genus would not be lessened by placing these insects under one name, at least 
without more specimens and some connecting links. The antenne might give differ- 
ential characters, but unfortunately are mutilated in the specimen described. 
Arocera splendens (p. 74). 
To the localities given, add :—-Mexico, Teapa in Tabasco (H. H. Smith); Guatemata, 
Volcan de Atitlan 2500 to 3500 feet, Pantaleon (Champion); Panama, Bugaba, Volcan 
de Chiriqui 4000 to 6000 feet (Champion). | 
This species varies greatly in size, the specimens now before me averaging from 14 
to 21 millim. in length.
