Subfusiform, subdepressed, subzeneo-brunneous, shining, punctate. Head strongly 
punctate. Antenne testaceous. Thorax elongate, broader in front than behind, with 
the sides rufo-testaceous, slightly rounded, broadest before the middle, translucent, 
scarcely margined but slightly reflexed, rugosely punctate, more especially in front, with 
the disk slightly convex, slightly impressed on each side before the base ; anterior angles 
nearly right-angled, posterior angles obtuse. Scutellum nigro-piceous or black, lightly 
punctate. Elytra broader and about a third longer than the thorax, a good deal broader 
than the base of the thorax, punctate-striate, punctures angular, interstices with a row 
of punctures, subquadrate ; the shoulders square and rather prominent, the sides almost 
parallel, the apex of each elytron truncate obliquely inwards and forwards, exterior 
apical angles rounded, sutural angles slightly obtuse; the base with an elongate spot 
near the suture, reaching almost from the scutellum to the apex, and another small spot 
in the middle, indistinctly subtestaceous. Abdomen with fimbriz and margins of last 
three segments below translucent and subtestaceous. Legs testaceous. 
From the Cape of Good Hope. 
Transition- Genera between the LATE-FIMBRIATA and ANGUSTE-FIMBRIATA. 
Genus MACROSTOLA (naxpoc, long; oroàù, vest: alluding to the elytra). 
Caput oculis maximis, tota capitis latera occupantibus; epistomate porrecto. Labrum integrum. Ligula 
angusta, alis membranaceis angustatis. Elytra elongata, striata vel seriatim punctata. Abdomen 
tribus segmentis expositis, haud fimbriatis, segmento secundo brevi, primo, tertio et quarto fere zequali- 
bus, ultimo longiore. 
Subconvex, elongate, conical both in front and behind. Head with the epistome pro- 
jecting. Antenne (Pl. XXXV. fig. 7 «) with the first article large and dilated, second 
smaller but thickish, third of same length as the second but more slender, fourth equal 
in thickness to but shorter than the third, fifth shorter and slightly thicker, sixth and 
seventh slightly thicker and more quadrate and about the same length as the fifth, 
eighth short and somewhat lenticular, ninth and tenth large, and eleventh smaller, these 
three forming a club so closely united as on a cursory view to look as if only composed 
of two articles. Labrum entire. Mandibles bicuspid at the apex. Maxille bearded on 
the inner side, without any tooth at the base. Maxillary palpi four-jointed, the second 
and third joint largest, the fourth conical. Ligula elongate and narrow, the tips of the 
paragloss:e visible on each side of the apex of the ligula*. Labial palpi three-jointed, the 
* The structure of the ligula and paraglosss in this species is very instructive. The ligula is seen in fig. 7 e, in
