Longicornia of Mexico and Central America. 171 



C. ctenostomoides has been found in some numbers 

 by Mr. H. H. Smith at Amula and Xucumanatlan in 

 Guerrero. 



Evander xanthomclas, Guer., Kev. ZooL, 1844, P- 258 

 [Amphidesmus) ; Bates, Biol. Centr.-Amer., Col., 

 v., pp. 72, 316. 

 Var. Elytris ochraceis, trienti apicali solum nigro ; cseteris 

 sicut in forma typica. 



Hah. Mexico, Monterey in Nuevo Leon (/%e). One 

 example ; the typical form occurring also in the same 

 locality. 



Athetesis convergens, n. sp. (PL VII., fig. 10). 



Valde elongata, fulvescenti-flava, incixmbenti-pubescens, collo, 



anteimis, thorace vittis duabus antice coiivergentibus, elytris fascia 



lata basali (nee marginem nee suturam attingenti) trienteque 



apicali, pedibusque (femoriun basi excepta) nigris. Caput relative 



parvum, ante oculos transversim quadratum, verticale, tuberibus 



antenniferis pauUo elevatis quadratis. Thorax trapezoideus, 



pauUo post medium angulatim dentatus, ante dentem recte angus- 



tatus, post dentem sinuatus baud angustatus, angulis posticis pro- 



longatis, dorso pauUo ingequaii, punctatus. Scutellum triaugulare 



nigrum. Elytra valde elongata, quam in A. prolixa latiora et 



minus cylindrica, apicibus late singulatim rotundatis, utrinque disco 



usque paiillo ultra medium tricostato, interstitiis apud fascias 



nigras minute et dense, apud fasciam medianam fulvam, gi-ossius 



et minus dense punctatis, marginibus breviter fimbriatis. Antennae 



( 5 ?) corporis dimidio perparum longiores, articulis 4—10 brevibus 



paullulum serratis. Subtus fulva nitida, metasterni lateribus 



abdominisque apice nigris. Mesosternum declive fere planum. 



Long. 19 millim., ? ?. 



Hah. Mexico, Amula in Guerrero, 6000 ft. {H. H. 

 Smith). One example. 



The genus Athetesis is very closely allied to Evander, 

 differing only in its long cylindrical form, and the 

 nearly plane, very short antennfe. The present species 

 is evidently congeneric with A. jn olixa, filihowgh the 

 anteriorly convergent thorax gives it a different facies. 

 This genus is new to the Mexican fauna.
