PSEUDOPHYLLIN^E. 



This sub-family is represented in Connecticut by only one 

 genus containing one species. 



Cyrtophyllus Burmeister. 



Head large and stout, with rather small roundish eyes ; vertex 

 compressed by the basal joints of the antennae, and extending for- 

 ward between the eyes, forming a small triangular spine, which 

 is grooved above. Prosternum armed with two short spines. 

 Pronotum nearly as wide dorsally as long, and cut by two trans- 

 verse sulci; surface rugose, with the posterior portion raised 

 above the rest of the pronotum. The tegmina extend beyond the 

 wings and are nearly half as wide as long, obtusely rounded 

 apically and concaved within. Sub-anal plate of male terminat- 

 ing in a long paddle-shaped appendage grooved on the upper 

 side. Ovipositor of female broad, the apical half with minute 

 teeth on the lower edge and curved upward. Apex with a rather 

 sharp point. Stridulating organ prominent, of a brown color, 

 with the central portion sunken and transparent. 



C. perspicillatus Linnaeus. True Katydid. Broad-winged 

 Katydid. Plate VI, 4. 



The true katydid is readily recognized by the broad wing 

 covers, which when closed curve around the body, so that the 

 edges touch above and beneath. The wing covers are dark green 

 in color and thickly netted with prominent veins so that they 

 much resemble leaves. The calling organ is large and well devel- 

 oped, which together with the peculiar shape of the wing covers 

 enables the katydid to produce the loudest note of all our locustids.
