LONGICORNIA. Ald 
of body. Lepturges dulcissimus, Nyssodrys bispecularis, N. pulverea, and N. letifica 
belong to the group, and also the following species :— 
6 (a). Nyssodrys vigintiguttata. (Tab. XXV. fig. 5.) 
NV. polyspile proxime affinis. Anguste oblongus, depressus; capite thoraceque albo-cinereis, hoc medio vittis 
duabus rectis nigris; elytris castaneis, griseo tenuissime pubescentibus, utrinque maculis circiter 10 
(quarum 3 marginalibus majoribus) late separatis subrotundatis, apice lineolisque suturalibus albo-cinereis ; 
antennis quam corpus duplo longioribus, nigris, subtus sparsim ciliatis, articulis 3°-10™ subequalibus, 
11° longissimo ; elytris basi discrete punctatis, stria suturali a medio usque ad apicem, apice recte trun- 
catis, angulo exteriori dentiformi; pedibus nigris, femoribus (gradatim leviter incrassatis) tibiisque 
griseo-pubescentibus, 
Long. 3 lin. ¢. 
Hab. Panama, Volean de Chiriqui (Champion). 
One example only. The head in front, as in WV. polyspila, is obliquely retracted, the 
lower lobe of the eye rather short and narrowed below. In JW. (Leiopus) polyspila, as 
White states, the thorax has numerous whitish spots, and each elytron from eighteen to 
twenty spots. 
6 (8). Nyssodrys univittis. (Tab. XXV. fig. 6.) 
NV. polyspila major, paullo convexior; capite thoraceque albo-cinereis, hoc medio vitta lata nigra ; elytris cas- 
taneo-fuscis griseo-sericeis, albo-cinereo irregulariter maculatis, humeros et apicem versus maculis in plagas 
majores agglomeratis, spatio cruciformi circumscutellari fusco; capite antice minus retracto; antennis 
quam corpus duplo longioribus, articulis 3°-10™ subzequalibus, 11° longissimo, subtus sparsim setosis, scapo 
gradatim leviter clavato; elytris apice subtransversim truncatis, angulo exteriori dentiformi, stria suturali 
a medio ad apicem ; tibiis et tarsis nigris, illis medio late albo-annulatis; pro- et mesosterno latissimis. 
Long. 8-4 lin. ¢. 
Hab. PanaMa, Volcan de Chiriqui (Champion). 
8 (a). Nyssodrys polytznia. (Tab. XXV. fig. 7.) 
N. letifice affinis et similis, forma eadem, fulvo-cinerea ; thorace vittis quatuor, elytris utrinque vitta suturali 
(fere usque ad apicem extensa) et marginali (interdum interruptis), vittisque duabus latioribus discoidalibus 
(1? a basi fere usque ad medium, 2* paullo posteriori), nigris; antennis pedibusque fuscis, femoribus basi 
flavo-testaceis. 
Long. 24-37 lin. 
Hab. Panama, Bugaba (Champion). Numerous examples. 
In WN. letifica the blackish sutural and discoidal stripes of the elytra end abruptly 
long before the apex, and are succeeded by a broadish straight fascia of the ashy-grey 
ground-colour, the margin and apex being spotless, or faintly clouded with fuscous. In 
NW. polytenia the sutural vitta (of irregular width) continues very nearly to the apex, 
and there is no grey fascia, the submarginal vitta reaching nearly to the suture, posterior 
to the end of the sutural vitta. The thorax, as in WV. letifica, is slightly dilated and 
angulated some distance from the base. Both species have slenderer hind femora than 
N. polyspila and other species of the group; but in the very short and flattened female 
ovipositor, with rounded dorsal segment, they agree with those species.
