meister, which last names they have received on account of the musical 
powers possessed by the males (jig. 114. 1. Cicada Anglica). These 
are the largest insects in the order, one species measuring between 
six and seven inches in the expanse of its wings. The head is short, 
broad, and transverse, with large prominent eyes (jig. 114. 2. front of 
head of Cicada atrata) ; the ocelli, three in number, are placed on the 
back of the head ina triangle; the face has a large nearly circular 
swollen and transversely striated piece, close to which, at the upper 
angles, and between the eyes, the antennz are inserted: these are, 
as it appears to me, composed of seven joints, although described 
as only 6 jointed by Latreille and others,—the basal joint being thick, 
and the others slender and gradually attenuated to the tip (fig. 
114.4.). The rostrum, promuscis, or, more strictly speaking, the la- 
bium, is greatly elongated and 3-jointed; the basal joint being very 
short (when seen from above, and in some species not perceivable), 
the terminal joint very long and slender (fig. 114. 2. ; 3. base of pro- 
muscis sideways); the mandibles and maxilla are represented by 
four fine sete passing through the promuscis, and the palpi are 
entirely wanting. The prothorax is short and transverse, the meso- 
thorax very large, the metathorax scarcely visible above, except 
at the sides; beneath these segments are nearly equal (fg.114. 7. 

eiccum, a thin skin, and 2s, signifying a sound produced by the motion of a little 
skin. Others derive it from the Latin words “ cito cadat,” implying that the Cicada 
soon yanish, or are short-lived. The Greeks named them ‘fettix, and the smaller mute 
ones Tettigonia; the last of which names has been given by Fabricius to the true 
Cicadze, whilst Latreille applied it to the smaller species. Purmeister conjectures 
that Cercopis sanguivolenta was the true Tettigonia.
