416 SUPPLEMENT. 
11 (4). Nyssodrys decemguttata. 
Nyssodrys calligramma, p. 181, var. t. 12. f. 17. 
Hab. Nicaraeva, Chontales (Belt); Panama, Volcan de Chiriqui, Bugaba (Champion). 
The anterior lateral spot of the elytra is always small, rounded, and distant from the 
margin, and the two submedian spots are separate or nearly so, never blended into a 
broad fascia as in WV. calligramma. It is generally more elongate in form. 
11(s). Nyssodrys sulphurescens. 
NV. calligramme quoad formam simillima, sed pedibus posticis ¢ longioribus femoribusque elongatis gradatim 
mediocriter incrassatis. Magis depressa, cinerascenti-sulphurea ; scutello elytrisque maculis 3 marginalibus, 
1* oblique oblonga, 2* undulata versus suturam valde angustata, 3* parva triangulari ante apicem, purpureo- 
nigris; antennis pedibusque fusco-nigris, illis articulis 1° 2°que toto 3° 4°que dimidio basali rufescen- 
tibus ; coxis et femoribus tibiisque basi pallide testaceis. 
Long. 3-4 lin. 
Hab. Panama, Bugaba (Champion). 
11 (c). Nyssodrys pictula. 
Oxathres pictulus, p. 175. 
To the Guatemalan localities given, add :—Rio Maria Linda, Cerro Zunil, Mirandilla, 
Pantaleon, Volcan de Atitlan, San Isidro (Champion). 
Generally distributed along the forest-region of the Guatemalan Pacific slope 
(Champion). 
In NV. pictula the apical ventral segment is bispinose as in Oxathres, but the female ovi- 
positor is not elongated and narrowed, with pointed and carinated dorsal plate, as in that 
genus. The species, in fact, approaches in structure very nearly WV. calligramma, having 
nearly the same form of thorax (angulated behind the middle), very broad mesosternum, 
and short lower lobe of the eyes; the apparently bispinose apical ventral segment results 
from the much deeper sinuate-truncature of the segment; the ovipositor is not much 
longer than the male apical segment, but is narrower, and the dorsal plate is obtusely 
rounded at the apex. The hind femora are rather more robustly clavate than in 
N. calligramma*. 
* A very similarly-coloured species of this group, with short lower lobe of the eyes, and interesting 
from the fact of the apical ventral segment having no trace of spiniform lateral angles in either sex, is the 
following :— 
Nyssodrys buckleyi, n. sp. 
Magis convexa, purpurascenti-cinerea; ‘elytris utrinque macula obliqua post scutellum fasciaque postmediana 
apud marginem latissima, nigro-purpureis velutinis; thorace longe post medium angulato et subdentato ; 
elytris apice transversim truncatis, angulo exteriori mediocriter producto; mesosterno latissimo ; femoribus 
pedunculato-clavatis, tibiis tarsisque apice nigris; pectore rufo, abdomine nigro; antennis scapo apice leviter 
clavato. 
Long. 32 lin.
