12 HEMIPTERA-HOMOPTERA. 
1. Proarna pulverea. 
Cicada pulverea, Oliv. Enc. Méth. v. p. 759. 61°; Germ. in Thon’s Ent. Arch. ii. 2, p. 43. 82. 
Proarna pulverea, Stal, Stett. ent. Zeit. xxv. p. 61°. 
Stoll, Cig. f. 72. 
Hab. Mexico, Vera Cruz ?.—Guiana, Surinam !. 
This species is inserted here on the authority of the late Professor Stal. We have 
not as yet received it from Central America. 
2. Proarna albida. (Tab. III. figg. 9, 9 a, 9d.) 
Cicada albida, Oliv. Enc. Méth. v. p. 755. 39*; Walk. List Hom. i. p. 160. 997. 
Proarna albida, Stal, Stett. ent. Zeit. xxv. p. 61. 
Stoll, Cig. f. 125. 
Hab. Costa Rica, Irazu (Rogers).—Trinipav (coll. Dist.)—Gutana, Demerara ? (coll. 
Dist.), Surinam!; Braztt, Para ?. 
This species is strikingly variable, both in size and also as regards the length of the 
second apical area of the tegmina. Stoll’s figure being very unsatisfactory, I have 
here figured a specimen from Costa Rica. 
Var. insignis. 
Body much broader than in any varietal forms of P. albida which have passed through my hands, lateral 
margins of pronotum more ampliated, markings of the tegmina darker and more distinct. 
©. Long. 24 millim., exp. tegm. 63 millim. 
Hab. Nicaracua (coll. Dist.); Panama (Boucard). 
Three females possessing this form have passed through my hands. As I have not 
seen the other sex, and can find no sufficient structural character in the female 
of specific value, I have felt it necessary to give a varietal name for the present, to 
prevent confusion. 
3. Proarna sallwi. (Tab. I. figg. 8, 8a, 80.) 
Proarna sallé, Stal, Stett. ent. Zeit. xxv. p. 61. 3887. 
Hab. Mexico, Vera Cruz}. 
The figure is from a typical specimen in the Stockholm Museum. 
4, Proarna championi, n. sp. (Tab. Il. figg. 14, 14 a, 143.) 
Body above dull testaceous, somewhat sparingly pilose. Head with the frontal margin, a. transverse fascia in 
front of eyes, and area of the ocelli black. Pronotum with two central longitudinal fascie, two oblique 
strize on each side, and inner lateral margin black. Mesonotum with two large obconical basal spots, 
bordered on each side by a larger obconical fascia, and a small transverse fascia on disk, preceded by two 
small rounded spots, black. Abdomen above somewhat thickly covered with white pile, and with the 
basal segmental margins fuscous. Body beneath paler; anterior submarginal fascia to head, central fascia 
and transverse ridges to face, and apex of rostrum black. Legs unicolorous, apices of tibie and tarsi 
testaceous. ;
