PLATE I. 
Fig. 1. Xeroph/Uum servillei, page 30. Imago, showing the foliaceous character of 
the femora, and the bark-like appearance of the pronotum. 
Fig. 1 a. Head, frons, and clypeus of the same insect. The absence of a proboscis 
and also of any apparent mandibles may be noted. Possibly a dissection of a 
recent specimen may show rudiments of cutting-jaws under the scale, below the 
clypeus. The antennae are short and filiform. 
Fig. 1(5. The fore leg much enlarged, with its leaf-like femur. 
Fig. 1 c. Middle leg of the same insect. 
Fig. Id. The broad femur of the hind leg, showing the extreme end of the tibia, 
furnished with spurs. The three irregular tarsal joints of the feet are certainly 
abnormal in form. 
Fig. 2. Xerophylliim corticis, page 31. A larger insect than the last, and showing 
certain differences in the pronotum. 
Fig. 3. Xeropltyllum minor , page 31. Considerably smaller, and having the femora 
less complex. 
Fig. 4. Membracis flaveohi, page 31. Imago. One of the largest insects of this 
genus. 
Fig. 4 a. Larval form, or possibly the exuvite or slough of the same. 
Fig. 4 b. Pupa of the same, showing the incipient growth of the pronotum of the 
adult insect. Also the small representatives of the tegmina and wings. 
Fig. 4c. Tegmen and wing of M. flaveola. 
Fig. 4 d. Front view of the same, with eyes, ocelli, and part of the pronotum seen 
edgewise. 
Fig. 4e. The middle and the hind legs. 
Fig. 5. Membracis fusca, page 33. Imago, with the pronotal edge corrugated and 
showing the peculiar valvular termination of the abdomen.
