CYMATODERA. 135 
Two specimens were taken by Mr. Champion, in both of which the sixth segment is 
a simple rounded ciliate plate. 
14. Cymatodera bipunctata. (Tab. VII. fig. 16.) 
Oblonga, postice paulo ampliata, ferruginea ; capite prothoraceque leviter punctatis ; elytris tenuissime pube- 
scentibus, obsolete punctato-striatis, singulis post medium macula parva nigra notatis. Long. 10 millim. 
Hab. Mexico, Oaxaca (Hége). 
Sufficiently distinguished by the uniform ferruginous colour, only relieved by two 
distinct black spots near the middle of the elytra. The head is covered with small 
distinct punctures ; and the thorax has them scattered here and there, and is finely 
wrinkled transversely near its base; but this sculpture is finer than usual. The elytra 
are very obsoletely striate ; and the punctures are very irregular, being usually composed 
of three confluent smaller ones ; these are often disposed transversely; and sometimes 
the interstices are broken up by the smaller punctures; the apex is nearly smooth at 
about four fifths. 
Two specimens are all that have been sent. 
15. Cymatodera cylindricollis. 
Cymatodera cylindricollis, Chevr. Col. Mex. Cent. i. fase. 1°; Klug, Mon. Abhand. Berl. Acad. 
1842, p. 271; Spin. Mon. i. p. 148, t. 10. fig. 3. 
Hab. Mexico 1, Cordova, Capulalpam, Parada, Durasnal (Sallé), Guanajuato (Dugis, 
coll. Sallé), J alapa (Hoge), San Luis Potosi (Dr. Palmer) ; Guatemaua (coll. Gorham), 
Quiche Mountains (Champion). 
A very distinct species, easily recognized by its rather robust build, antenne about 
half as long as the body, very finely punctured and much compressed thorax, elytra 
with striz continued to near the apex, and almost uniform brown colour, the head and 
thorax and a large subapical patch on the elytra being usually darker. 
It appears to be a common species in Mexico. 
16. Cymatodera hogei. 
Elongata, subparallela, nigro-picea, subtilissime punctata, nitida; corpore subtus elytrorumque apice rufo- 
piceis; elytris punctato-striatis striis fere integris, fascia mediana pedibusque pallidis, geniculis fuscis, 
Long. 17 millim. -¢ 9. 
Hab. Mexico, Jalapa, Trapiche (Hége); GuaTemata, San Gerdnimo, Capetillo 
(Champion). 
Head as wide as the elytra at the base, finely and closely punctured; epistoma and 
mouth, breast and sides of the abdomen ferruginous. Thorax shining; very fine rugee 
are visible on the centre of the disk ; and in the Guatemala specimens (which are smaller 
and possibly belong to a distinct species) the whole surface is distinctly punctured.
