CTENOCHIRA. 229 
C. sertata, Boh. (=varians, Wag.), is an allied form occurring in Tropical South America. 
We figure a typical () C. vivida from Teapa; a specimen (¢ ) of the var. nigrocincta 
from Chiriqui; and a brightly-coloured example ( 2 ) of the var. tabida from Chiriqui. 
14. Ctenochira punicea, (Tab. XIII. fig. 11, ¢.) 
Coptocycla punicea, Boh. Monogr. Cassid. iii. p. 4941, and iv. p. 4827; Cat. Col. Ins. Brit. Mus. 
ix, p. 200° (excl. var. a). . 
Hab. Muexico!~®, Acapulco, Teapa in Tabasco (Hége, H. H. Smith), Playa Vicente, 
Cordova (Sallé), Cerro de Plumas (Hoge), Temax in North Yucatan (Gaumer); BritisH 
Honpuras, R. Hondo (Blancaneaux); Guatemaua, Panzos (Champion); NIcaRAGuA 
(Belt, Janson); Costa Rica (coll. Baly). 
This insect differs from some of the varieties of C. vivida only in its paler colour— 
the black patch on the prothorax being replaced by a sanguineous edging and some 
small similarly-coloured spots, and the black annulus on the elytra replaced by a narrow 
marginal stripe,—and in having the eighth and ninth joints of the antenne infuscate. 
This last-mentioned character, however, is not constant. Boheman’s description was 
taken from an example with the disc of the elytra dilute sanguineous: in the speci- 
mens before me it is flavo-testaceous, with the punctures and margins sanguineous. 
Sent in abundance from Teapa, in company with C. vivida and its var. tabida. 
15. Ctenochira plebeja. (Tab. XIII. fig. 12.) 
Coptocycla plebeja, Boh. Monogr. Cassid. ili. p. 516+, and iv. p. 485°; Cat. Col. Ins. Brit. Mus. 
ix. p. 203°. 
Coptocycla cincta, Sturm, in litt. 
Hab. Mexico 1-8 (Sallé, ex coll. Sturm), Matamoros Izucar, Playa Vicente, Cordova _ 
(Sallé), Cerro de Plumas, Jalapa (Hége), Atoyac in Vera Cruz, Teapa in Tabasco 
(H. H. Smith); Nicaraava, Chontales (Belt, Janson). 
Sent in plenty from Teapa, in company with C. vivida, C. punicea, and C. hiero- 
glyphica. It is nearest allied to C. punicea, from which it may be distinguished by the 
definite markings on the prothorax and by the antenne having only the tip of the 
apical joint black. Boheman’s description appears to have been made from specimens 
with the dark markings on the thorax partly obliterated; in most of the examples 
before me the prothorax has a large subtriangular black patch, enclosing nine flavous 
spots (as in C. cumulata), these varying in size and often becoming more or less 
confluent. In the specimens from Chontales the dark markings on the prothorax 
are reduced to small disconnected spots. We figure a specimen from Atoyac. | 
16. Ctenochira coronata. (Tab. XIII. figg. 13, 2; 14, 6, var.) 
Coptocycla coronata, Boh. Monogr. Cassid. iii. p. 515’, and iv. p. 4857; Cat. Col. Ins. Brit. Mus. 
ix. p. 203°. .
