ROCCONOTA. 273 
Connexival segments 1 and 2 each armed with a curved spine at the outer apical angles. Legs very 
elongate; anterior femora strongly incrassate. 
Length 21, breadth of the abdomen 43 millim. — 
Hab. Mexico, Atoyac in Vera Cruz (Schumann). 
One specimen. ‘This species is very like Heza similis, agreeing with it in the 
armature of the pronotum, but differing from it in the non-plicate mesopleura, as well 
as in the posteriorly narrowed head, &c. The insect is probably bright red in life. 
2. Rocconota leviceps, n.sp. (Tab. XVI. fig. 20, 2.) 
¢. Elongate, rather robust, shining, sparsely pilose ; testaceous, the lateral portions of the head slightly 
infuscate, the pronotum broadly nigro-fuscous at the sides, the tips of the spines flavous, the corium fuscous 
to near the tip, the inner basal portion excepted, the connexivum with a series of black spots; the antenne 
with joints ] and 2 flavo-testaceous, annulated with fuscous, 3 and 4 ferruginous, 3 flavous at the base ; 
the femora each with two faint annuli towards the apex, and the tibie with a single annulus near the 
base, dilute fuscous. Head a little shorter than the pronotum, smooth and shining, armed with two very 
long spines. Pronotum with two long spines on the disc of the posterior lobe and a long outwardly- 
directed spine at each of the lateral angles; the anterior lobe transversely wrinkled, smooth, with the 
tuberculiform angles obtuse and prominent; the posterior lobe rugulose. Scutellum with an upwardly- 
curved spine at the apex. Abdomen wider than, and nearly reaching the apex of, the elytra, the first 
two connexival segments each armed with a rather long spine at the outer apical angles. Venter smooth 
and shining. . 
Length 14; breadth of the pronotum 33, of the abdomen 4? millim. 
Hab. Guatemata, Senahu in Vera Paz (Champion). 
One specimen. Very like &. annulicornis, but smoother and more shining above and 
beneath, the second connexival segment, as well as the first, armed with a long spine, 
the anterior angles of the pronotum obtuse, the under surface clothed with long hairs 
only. The head is much more elongate than in KR. octispina. 
3. Rocconota annulicornis. (Tab. XVI. fig. 21, ¢.) 
Heza annulicornis, Stal, Enum. Hemipt. ii. p. 77'; Uhler, Proc. Calif. Acad. Sci. (2) iv. p. 283°. 
Hab. Nortu America, Texas, Lower California ?.—Mexico (Sichel and Bilimek, in 
Mus. Vind. Ces.), Vera Cruz (Sallé', in Mus. Holm.), Atoyac (H. H. Smith), San 
Lorenzo (M. Trujillo), Temax in North Yucatan (Gaumer); GuaTEMALA, Paso Antonio 
(Champion). 
We have received six examples of this species, and three others have been seen, 
inclnding one of the types. There is no trace of a tubercle or plica on the mesopleura 
in front, the insect therefore cannot belong to Heza. RB. annulicornis is closely allied 
to R. tuberculigera, but differs from it in having the first connexival segment armed 
with a spine at the outer apical angles; it is also more pubescent, the scutellum is less 
produced at the apex, and the pronotal spines are flavous at the tip. The basal joints 
of the antenne are more or less distinctly annulated with brownish or fuscous, as are 
also the femora towards the apex and the tibiz at the base. ‘The under surface is very
