MEMBRA ClDJE. 
Genus: SCALMOPHORUS,* Fowler. 
Fowl. Biol. Cent. Amer., p. 24. 
A genus ciliefly remarkable for the complex reticulated tegmina. Stal’s genus 
JEclmopliora differs in not having this reticulation, and in the character of the 
pronotal horn, “ valde nutans ” (much bent down ?), which scarcely agrees with Canon 
Fowler’s genus. 
SCALMOPIIORUS RETICULATUS, Fowler. 
(Plate VIII. figs. 5, 5a.) 
Scalmophorus reticulatus, Fowler, Tab. II. figs. 11, 11a, lib, p. 22. 
Colour eoncolorous ferruginous-brown ; pronotum sharply acute at the anterior end, 
but rapidly thickening towards the head ; dorsum nearly straight, with a row of 
small obscure white dots on the edge ; first and second pairs of legs weakly spatulate ; 
tegmina with a more complex reticulation than that found in Philya. This character 
and the more robust horn, chiefly marks this insect from that genus. 
I give an outline of a tegmen, which has been adapted from the neuration 
shown in the B.C.A. My drawing is from a rather mildewed specimen kindly lent 
to me by Canon Fowler. 
Size, 7x2 mm. 
Habitat. —Guatemala; San Geronimo, 3000 feet; Cerro Zunil, 4000 feet 
altitude. 
Some specimens appear to have more transparent membranous wings than others. 
Genus: IlYPSOPRORA, Stal. 
Stal, Ofv. Kongl. Vet. Akafi. Forh. 2G, p. 27 7 ; Fowler, B.C.A. ii. p. 25. 
jEchmophora , Stal. Uypsoprora, Fowler. 
Head prolonged more or less into a single erect process (procephalon), the summit 
of which is round, expanded or obtuse ; the dorsum may be sinuous and tubercular, 
or furnished with rounded smooth humps. 
The genus at present contains but few species. When they are more plentiful 
and better known, probably they may be, with advantage, sub-divided. 
* From a fanciful resemblance to the thole-pin of an oar.
