LEPTODICTYA. 238 
LEPTODICTYA. 
Leptodictya, Stal, Enum. Hemipt. iii. pp. 121, 127 (1878). 
In this genus the reticulation of the elytra is close, the subcostal area (costal of 
Stal) is very narrow and biseriate, and the costal area has four depressed oblique 
transverse nervures or folds. The expanded opaque margins of the pronotum are 
formed by two layers of membrane meeting on the outer edge, this being easily seen - 
when the insect is viewed sideways *. The rostrum about reaches the end of the 
metasternum. The wings do not extend beyond the abdomen. 
The Central-American species may be thus tabulated :— 
Discoidal area of the elytra with an adventitious nervure extending from 
the inner margin forwards; pronotum with the membranous margins 
straight, angularly projecting in front ; antenniferous tubercles distinct : 
integument pale stramineous . . . . . . +. - . . . « . tabida, H.-S. 
Discoidal area of the elytra without adventitious nervure. 
Pronotum with the membranous margins slightly rounded ; antenniferous 
tubercles obsolete: integument in great part hyaline . . . . . cretata, n. sp. 
Pronotum with the membranous margins straight and converging from 
the base; antenniferous tubercles distinct: integument in great 
part fuscous. . 2. 2 1 6 ee we wee we ew we CtrCumCinet a, D. Sp.

Hab. Mexico1?; GuatTEMaLa, Coatepec, Capetillo (Champion). 
Four specimens from Guatemala, agreeing well with Herrich-Sehaffer’s figure. This 
species was unknown to Stal, who (Enum. Hemipt. iii. p. 134) suggested its affinity 
with Leptostyla, Leptopharsa, and Leptodictya. The insect evidently belongs to 
Leptodictya, near L. fuscocincta, Stal, from Rio Janeiro. In the present species the 
discoidal area of the elytra is very large, extending to beyond the middle, limited 
inwards by a sharply raised nervure, from the hinder part of which an oblique 
nervure extends forwards. The membranous margins of the pronotum are straight, 
converging from the base forwards, and project angularly in front. The elytra, when 
closed, are somewhat oval in shape, tapering from the middle. The head has a 
small spiniform antenniferous process on either side. 
2. Leptodictya cretata, n.sp. (Tab. II. figg. 11; 11a, profile; 114, part of 
the body beneath.) 
Moderately elongate, rather broad; body black, the integument whitish and partly hyaline; the elytra with 
the nervures beyond the middle, and also those along the costal margin thence to the base, fuscous or 
* Of the five species described by Stal, one only (L. fuscocinetu) has been seen by me.
