_TENODEMA. 619 
2. Tenodema ornatum. (Tab. XVI. fig. 10.) 
Angustum, nigrum, nitidum ; capite, prothorace elytrisque viridi-cyaneis, antennis palpisque flavis, illis extrorsum 
fuscescentibus ; pedibus rufis, intermediorum tibiis tarsisque fusco-rufis, posteriorum tibiis tarsisque nigris ; 
capite prothoraceque dense fortiterque punctatis, nitidis ; elytris parce punctatis. 
Long. 19 millim. 
Hab. Mexico, Cordova (Sallé). 
Antenne not elongate, yellow, with the three terminal joints infuscate. Head 
coarsely, very densely punctate. Thorax a little longer than broad, very coarsely punc- 
tate. Elytra longer than the thorax; sparingly, irregularly, rather coarsely punctured, 
very shining. Hind body with the exposed dorsal membrane of the first and fourth 
segments entirely white, of the second and third black with white extremities. 
This species has many points of difference from T. stigmaticum, to which, however, 
it is more nearly allied than to any of the others. Unique. 
3. Tenodema nigripes. 
Nigerrimum ; antennarum basi, palpis tarsisque anterioribus fusco-testaceis, capite prothoraceque nigro-zneis, 
elytris eneis, parce punctatis ; capite prothoraceque fortiter punctatis, hoc marginibus fere impunctatis. 
Long. 16 millim. 
Hab. Guatemata, Teleman (Champion). 
Var. mexicana. Elytris minus obsolete punctatis, 
Hab. Mexico, Cordova (Sal/é). 
Antenne only moderately long. Head closely, very coarsely punctate, with a small 
transverse space on the vertex impunctate. Thorax quadrate, closely and coarsely 
punctate on the disc, but with the lateral and basal margins rather broadly impunctate, 
Elytra of a brighter metallic tint than the anterior parts, distinctly but not greatly 
longer than the thorax; sparingly and finely punctured, a little more closely so about 
the suture. Hind body intensely black, with the exposed membranes in part white. 
If the Mexican example be indicative of a distinct species, it must be an extremely 
closely allied one; as we have received only one example of the type and one of the 
variety, I cannot speak very positively. The Amazonian 7. guadratum is another allied 
species. 
4, Tenodema hemorrhoidale. (Tab. XVI. fig. 11.) 
Nigerrimum, nitidum ; antennarum basi, palpis tarsisque anterioribus fusco-rufis ; capite, prothorace elytrisque 
viridi-gneis, abdomine apice rufo ; capite prothoraceque fortiter punctatis, hoc marginibus fere impunctatis ; 
elytris quam prothorax vix longioribus, parce punctatis. 
Long. 12 millim. 
Hab. Panama, Volcan de Chiriqui, Tolé (Champion). 
This species agrees in most respects rather closely with 7’. nigripes, but is apparently 
a considerably smaller insect, with red extremity to the body. We have only one 
specimen from each locality. We figure the example from Tole.
