The writer collected two females at Meridian, Aug. 14, 

 1921, a male at Aberdeen, June 26, 1921, and a male at 

 Hattiesburg, Aug. 10, 1921. This species occurs also in 

 low deciduous woods but is far less common in Mississippi 

 than Cotyleceps delicata. 



THE GENUS Cixius LATREILLE 



This genus was erected in 1804 by Latreille (Hist. Nat. 

 Crust. Ins., xii, p. 310) and is well represented in Europe 

 and the New World. Seven species have been recorded from 

 North America but the record of .albicinctus is probably 

 based on an erroneous determination. Three species are 

 known to occur in the Southern States. 



What little is known of these plant hoppers indicates that 

 they are tree and shrub inhabiting. Some show a decided 

 preference for conifers, such as the spruce and pine. One 

 species, stigmatus SAY, seems to feed on grasses and sedges 

 in low wet places . 



The genus is very closely related to Monorachis and Oliarus and 

 may be briefly characterized as follows: Vertex short, four angled, 

 together with the large but inconspicuous eyes, narrower than the 

 pronotum, separated in front from the frons by a transverse ridge; 

 four compartments are formed by the median longitudinal carina and 

 an anterior transverse one, the two hind compartments larger than 

 the front ones. Frons with a median longitudinal carina, at the apex 

 of which is placed an ocellus. Pronotum very short, angularly emargi- 

 nate behind, the lateral carinae curved out behind the eyes and 

 attaining the lateral margins. Scutellum large and tricarinate. Elytra 

 longer than the abdomen, broadly rounded at apex; nervures punc- 

 tated with more or less distinct black dots, from which areas arise 

 fine fuscous hairs; stigma distinct. Wings present. Hind tibiae 

 with two or three spines, nearly always three. Logotype of the genus : 

 Cixius nervosus Linn. 



The following key has been adapted from Van Duzea 

 Key to the species of Cixius. 



Elytra hyaline or slightly enfumed, frequently more or less banded 

 or maculated with fuscous; nervures with brown punctures, 1. 



1. Vertex distinctly transverse, at most obtusely angled before; ely- 

 tra proportionately broader; outer sector of the corium forked as 

 near to or nearer the base than is the inner; maculation trans- 

 verse, 2. 



.. Vertex a little longer than broad, triangular, its apex subacute; 

 elytra proportionately narrower; outer sector of the corium forked
