208 LONGICORNIA. 
ERANA. 
Erana, Bates, Ann. & Mag. Nat. Hist. ser. 3, xvii. p. 481 (1866). 
Although widely separated from it by Lacordaire, this genus differs from Essostrutha 
only by the much slenderer antenne, the greater length of the scape, and the fringe of 
hairs above, as well as beneath, the joints. The difference in the width of the head, 
and its consequent more or less retractility within the thorax, is very slight, the head 
being relatively broader in Hrana than in Kssostrutha. The Brazilian species Saperda 
triangularis (Germar), which I had referred to the genus, must be removed from it. 
The following Central-American species differ somewhat from the generic type, E. cine- 
ticornis, in the greater length and slenderness of the antenne, of which the third joint 
is very long and slightly curved; but in the length and shape of the scape and pilosity 
of these organs they agree very well with £. cincticornis. 
1. Erana pusilla. 
Erana pusilla, Bates, Trans. Ent. Soc. 1873, p. 2337. 
Parva, linearis, supra subplanata, erecte tenuiter pilosa, subtus nigra episternis albis, supra colore variabilis : 
6 fulvo-rufa vel fulva, capite et thorace lateribus elytrisque sutura et vitta laterali fusco-nigris ; 
Q cinereo-nigra, capite thoraceque medio rufo-fulvis, vel nigra capite thoraceque medio fulvis vel toto 
nigris, thorace linea mediana cinereo-fulva ; antennis fulvis, scapo nigro; pedibus ¢ toto fulvis, 9 fulvis, 
quatuor posterioribus nigro-variegatis vel nigris, duobus anticis tantum fulvis; elytris apice ¢ rotundatis, 
@ angulo suturali breviter dentiformi. 
Long. 33-33 lin. ¢ Q. 
Hab. GuaTEMALA, Duefias, San Gerénimo (Champion) ; Nicaragua, Chontales (Belt)!. 
The original description above cited was drawn up from a single female specimen 
taken by Mr. Belt. Mr. Champion having since sent home a good series of both 
sexes, I have been enabled to complete it, especially with regard to the variation in 
colour. 
2. Erana pectoralis. 
E, pusille proxime affinis, at differt abdomine plus minusve fulvo. Parva, supra subplanata, densius erecte 
pilosa ; subtus nigra, abdomine fulvo vel cinereo-nigro lateribus aut apice fulvis, episternis flavis; supra 
colore variabili; ¢ fulva, thorace plaga laterali, elytris vittis laterali et suturali nigris; 9 elytris nigris, 
capite et thorace vel toto fulvis vel fulvis thorace plaga laterali nigra ; antennis fulvis, scapo et articulis 
2° toto, 3° et sequentibus apice nigris, tertio plus minusve piceo; pedibus utriusque sexus flavis, tibiis et 
tarsis nigrescentibus ; elytris apice ¢ ? rotundatis. 
Long. 23-34 lin. ¢ 9. 
Hab. Muxico, Cordova, Orizaba, Tuxtla (Sal/é); Guaremata, San Isidro (Champion). 
This species has been known for a long time in collections as Phytecia pectoralis, 
Chevr., MS., a name which I have adopted. Its points of difference from E. pusilla 
are slight, but they seem to be of specific value when a numerous series of each is 
examined.
