GHILIANELLA. 171 
prominent. The inflated apical portion of the abdomen is somewhat piriform in 
shape in the female. 
2. Ghilianella bulbifera, n. sp. (Tab. X. fige. 17,174, ¢; 18, part of the 
abdomen, °@.) 
Slender, opaque, piceous or obscure ferruginous, the abdomen more or less mottled with black in the female,. 
the inflated portion and the apex of the sixth segment usually black in the male, the legs annulated with 
ochraceous ; finely pubescent, the head and thorax sparsely granulate. Head with a curved yellowish 
frontal spine, the eyes prominent; antennse with joint 2 very little shorter than 1. Pro- and meta- 
thorax subequal in length, the mesothorax more elongate, the meso- and metathorax abruptly widened 
posteriorly. . 
¢. Abdomen with the first and second segments long and narrow; the fourth segment and the apical half of 
the third abruptly, conjointly, and arcuately inflated at the sides, gibbous above and beneath, the third 
dorsal segment feebly subangularly dilated on each side at the apex; the fifth dorsal segment subparallel ; 
the sixth dorsal segment long and moderately acuminate, not quite covering the apex of the terminal 
genital segment, strongly curved upwards posteriorly, without median carina; the long terminal genital 
segment greatly inflated beneath. 
@. Abdomen gradually inflated from a little below the base of the third segment to about the apex of the: 
fifth and then narrowed to the apex, the inflated portion oval in shape; the fifth dorsal segment angularly 
dilated at the apical angles, and with a prominent tubercle in the centre a little before the apex; the sixth 
dorsal segment widening forwards and truncate behind; the two genital segments abruptly declivous. 
Length 20-22 millim. 
Hab. Panama, Bugaba (Champion). 
Found in numbers at Bugaba, males preponderating. Very like G. cgnorata, Dohrn, 
but differing from it structurally in both sexes: the males have a more slender 
abdomen, the apex of which is still more curved upwards, and the sixth dorsal segment 
is much less acuminate (not covering the tip of the inflated terminal genital ventral 
segment) and not carinate; the females have the inflated apical portion of the abdomen 
oval in shape (instead of piriform), the fifth dorsal segment with a conspicuous tubercle 
in the middle behind. 
8. Ghilianella granulata, n. sp. (Tab. X. fig. 19, head, thorax, and 
anterior leg.) 
Slender, opaque, almost glabrous, ochraceous, the head and thorax indeterminately fuscous at the sides, the 
anterior legs and the intermediate and hind femora faintly annulated with fuscous, the intermediate and - 
hind tarsi fuscous; the head and thorax sparsely and conspicuously granulate. Head with a porrect,. 
acute frontal spine, the posterior half gradually narrowed behind and very finely canaliculate down the. 
middle, the groove continued down the anterior part of the pronotum, the eyes small and not prominent ; 
antenne with joint 2 much shorter than 1. Pro- and metathorax subequal in length, the mesothorax 
much more elongate ; the mesothorax considerably, the metathorax slightly, widened behind. Abdomen 
with segments 1-4 filiform (the rest broken off). 
Length (to apex of fourth abdominal segment 19) ? about 25 millim. 
Hab. Brivish Honpuras, R. Hondo (Blancaneaux). 
One example. This species being abundantly distinct from the other Central-: 
American forms, I have ventured to name it, the mutilated condition of the abdomen 
notwithstanding. The small, non-prominent eyes, the finely canaliculate basal portion
