308 REPORT UNITED STATES ENTOMOLOGICAL COMMISSION. 
an ordinal group of Phyloptera, equivalent to the Orthoptera. The larval 
Forfleula is very close to Japyx in the form of the head, the thoracic 
homonomous segments, in having ten uromercs, in the nature of the for- 
ceps, and in the eleventh rudimentary segment. So close is the resem- 
blance that wo are somewhat inclined to regard Japyx as a degraded 
Forfleula. When we consider the nature of the head, the elytra-like fore 
wings, the singular hind wings, which are not net-veined, and the for- 
ceps, we see how much unlike the Orthoptera Forfleula is. It does not 
approach Blatta nor Tenues. Iu the character of the wings and the 
thorax, especially the pleurites, Forfleula is suggestive of the Ooleo- 
ptera, though differing from them in being ametabolous. 
In Labia the head is as in Forfleula. The body being much shorter 
and thicker than in Forfleula, there are some relative differences from 
what has been described in Forfleula. 
Notum. 
The pronotum is shorter and broader, but still covers the mesonotum ; 
the latter is as in Forfleula, the scutellum being similarly spine-like. 
The metanotum is as in Forfleula, with no important differences; the 
scutellum is rather more distinct, however, but the postscutellum is 
much shorter, and has similar, lateral, submembrauous folds iu front. 
The first uromere, with its spiracle, is much as in Forfleula, while the 
succeeding uromeres are much shorter. 
Pleurum. 
The protlioracic pleurites (episternum and epimerum) are as in For- 
ficula, but shorter and broader. 
In the mesothorax the epimerum is much rounded, being, with the 
episternum, rather shorter than in Forfleula. 
The inesothoracic pleurites are as in Forfleula, but much shorter and 
wider in proportion. 
Sternum. 
The sternites are not essentially different from those of Forfleula, but 
are rather shorter and broader. 
THE LARVA OP FORFIOULA (PI. XXIV). 
The notum of each segment is. as iu all Orthopterous larvae, simple, 
not being differentiated into scutum, scutellum, etc. On the other hand, 
the sternites and pleurites are as in the adult, and this proves that the 
tergites are concerned in and modified by the development of the wings. 
The epistorna are subdivided as in the adult. 
In the abdomen there are eleven uromeres, but the first tergite is 
wanting, the urosteruite being present, while the eleventh tergite is 
small and rudimentary.
