PHYLLOTROPIS HUMILIS. 
(Plate IY. figs. 3, 3a.) 
Membracis humilis, Fowler (Tab. I. figs. 6, 6a, p. 6.) 
Rather a small species. Pronotum black, with three white spots; legs black. 
By permission my figure is from the drawing in the Biologia Centrali-Americam. 
Size, 8x4 mm. 
Habitat .—Vera Cruz. 
PHYLLOTROPIS QUADRICOLOR. 
(Plate IV. fig. 4.) 
Enchenopa quadricolor, Walk. Ins. Saund. Homop. p. 60 (1858). Enchenopa subangulata, Walk, 
l.c. p. 61. Enchenopa excelsior , Walk. Enchenopa humilis , Walk. Enchenopa curvicorne , 
Walk. Enchenopa quadricolor , Fowler, B.O.A. Tab. I. figs. 16 and 17, p. 11. 
This species gives a good example of the variability of the genus. Thus the 
characteristic pronotal horn may or may not be present and the colours are also 
variable. The red colour on the fore part of the pronotum as given in my figure may 
be bright or even suppressed, but the white punctured patches seem to be persistent. 
The eyes, the tarsi, and sometimes the femora are bright red. The hind femora 
serrated. 
Size, 7x4 mm. 
Habitat. —Mexico, Vera Cruz, Venezuela. 
Genus: CliYPTONOTUS* n.g. 
This genus may be best described by the almost unique type specimens, assisted 
by the diagnosis below, and the figures on the plate. 
CRYPTONOTUS MILITARIS, n.s. 
(Plate III. figs. 8, 8a.) 
Large, with the ridge of the pronotum sinuous-convex ; anterior part overhanging 
the head, and ending at the posterior part with a black point; a semicircular broad 
whitish band over the region of the shoulders, and a continuous orange-red circular 
patch over the tail end ; the rest of the pronotum is jet black ; tegmina dark blackish- 
grey, with black neuration ; first and second pair of legs black, and broadly spatulate. 
This showy insect is not represented in the British Museum, but there are two 
specimens in the Hope collection, one obtained by Birchell from Sao Paulo, Brazil, 
the other by Bates from the Amazons. 
Size, 15 x 9 mm. 
* N.B. kfjh'TTTos, crooked.
