ARRHENODES. 45 
San Juan, Chacoj, Tamahu, Cubilguitz, and Coban, all in Vera Paz (Champion) ; 
Nicaraaua, Chontales (Belt, Janson). 
This species varies greatly as regards the size and development of the male; but the 
colour and the yellow marks are remarkably constant. Our series amounts to nearly 
seventy examples, 
3. Arrhenodes goudoti. 
Arrhenodes goudoti, Kirsch, Berl. ent. Zeitschr. 1867, p. 215°. 
Niger, thorace rufo trivittato ; elytris aurantiaco-vittatis. 
Long. 103-24 millim. 
Hab. Guaremata (Sallé), Panzos and Teleman in Vera Paz, El Tumbador, Cerro 
Zunil, Las Mercedes, Zapote (Champion); Panama, Bugaba, Volean de Chiriqui 
(Champion).—CotomB1A, Bogota} (coll. Sharp). 
Var. Corpore rufo-obscuro, thorace nigro-bivittato. 
Hab. Mexico, Toxpam (Sal/é). 
Closely allied to A. flavolineatus, but readily distinguished by the black colour of 
the body and appendages, and by the more complex marks on the elytra. Head short 
behind the eyes; head and metarostrum above usually more or less rufescent ; antenne 
black. Thorax black, with a broad red stripe along the middle and one on each side ; 
sternum sometimes vaguely rufescent in front. Elytra seriately punctate ; the inter- 
stices carinate to a variable extent—the third rufescent from the base to the apex, with 
a rather short interruption on the middle; the fourth with a rather short yellow mark 
outside of the interruption of this colour on the third interstice ; the fifth sometimes 
with a dot outside the mark just mentioned, but sometimes with no red mark; the 
sixth with a short mark placed scarcely farther forwards than that on the fourth; the 
seventh with a mark a little in front of the apex, occasionally with a dot outside the 
mark on the sixth interstice; eighth with a long line from the shoulder extending 
nearly half the length. Apices of the elytra only very obscurely bidentate. Abdomen 
sometimes rufescent along the middle. 
Our series of A. goudoti numbers about fifty examples; though the male is 
extremely variable in size and development, the red markings may be relied on for the 
determination of the species. | 
The only exponent we have received from Mexico is of pallid colour, and to a 
certain extent intermediate between A. youdoti and A. flavolineatus. 
4. Arrhenodes concolor, sp. n. (Tab. II. fig. 13, head with mouth open.) 
Angustior, rufo-brunneus, elytris flavo-signatis. 
Long. 15-24 millim.
