NOTOGONIA.— TACHYTES. 59 



and nearly as long as, the thorax, the apex acuminate, the segments broadly pilose at 

 their apices. Pygidium elongated, the apex rounded, densely covered (except upon an 

 elongated cone-shaped space at the base) with a fulvous pile, impunctate ; beneath, and 

 the penultimate segment also, with scattered punctures. Legs pruinose, the hair on 

 the spur and metatarsus reddish-fulvous. 



v 11. Notogonia panamensis. (Tab. IV. fig. 17, <* .) 



Nigra, cinereo-pubescens ; facie apiceque metanoti argenteo-pilosis ; area pygidiali pube fulva obtecta; oculis 

 in vertice fere longitudine antennarum articuli tertii inter se distantibus ; alis flavo-hyalinis, apice fere 

 fumatis. 



Long. 10 millim. 



Hab. Panama, Bugaba, Volcan de Chiriqui 2500 to 4000 feet (Champion). 



Antennae almost bare ; the basal joint somewhat longer than the second and third 

 joints united; the second joint one third the length of the third, the latter, if any- 

 thing, longer than the fourth. Vertex and front but very slightly pilose ; the face and 

 clypeus covered with golden or silvery hair. Eyes at the top separated by the length 

 of the third antennal joint. Front moderately depressed ; an indistinct furrow above 

 and a very distinct and broad one below the ocellus, and there is a longish furrow 

 which commences a little below the latter and reaches to the antennas. Clypeus 

 rounded at the apex, shining and impunctate there, and with a small incision in the 

 middle. Mandibles rufous towards the centre, the central furrow deep. Thorax opaque, 

 alutaceous, sparsely covered with a short pale pile, the pile more distinct on the meta- 

 thorax, especially on either side of the metanotum, where it assumes a fulvous hue. 

 Mesonotum slightly depressed in front ; metanotum finely coriaceous, narrowly furrowed 

 down the middle, the apex oblique and with the furrow wider and deeper. Abdomen, 

 if anything, longer than the thorax, elongate, narrowed gradually towards the apex, 

 the latter bearing a silvery or fulvous pile, opaque, almost alutaceous. Pygidial area 

 with the bristles dark fulvous and intersected with silvery hairs ; the apical bristles 

 stout, dull fulvous. Beneath and at the base the apical segment is sparsely punctured ; 

 the penultimate ventral segment is also sparsely punctured, and the middle segments 

 bear a silvery soft pubescence. Legs pruinose ; the spines and spurs black, the meta- 

 tarsal brush fulvous. Third cubital cellule hardly extending beyond the apex of the 

 radial cellule; the second cellule at the top is as wide there as the third; the 

 recurrent nervures are united.
