6 SJÖSTEDTS KILIMANDJARO-MERU EXPEDITION. 17: 1. 



ZU den Bergwiesen; ca. 3,000 m., unter Moos auf Bäumen. » IL 06. 18 males, 17 females, 

 and 22 immature specimens. 



This is a very distinct species; in the black body and read head it resembles 

 A. laeta Gerst., but is considerably larger and the characteristic forceps easily 

 distinguish it; it resembles that species in having the sides of she dorsal abdominal 

 plates terminating in a convexity towards the apex of the abdomen, but tliis convexity 

 is less pronounced than in that species, and instead of being furnished with one 

 horizontal carina, the sides of these rings are rugulose. 



The forceps are beut as in the typical species of the genus, A. maritima, but 

 the bend is much more abrupt; the shape of the forceps and the tooth near the base 

 recall A brunneri, from Australia, but in that species the coloration is different, the 

 basal tooth of the forceps is blunt, not sharp, and the branches are bent and not 

 abruptly angled. 



It is undoubtly allied to a hitherto undescribed species from Nyassa, in my 

 coUection, of which I append the description for purposes of comparison. 



It also resembles A rufescens Kirby, from West Africa, but the coloration is 

 different and the forceps are not the same. 



Aiiisolabis iufelix n. sp. 



Statura majore; colorc uigro; capite fusco-castaneo; antennae segmentis 4 et 2 brevibus, couicis, ceteris 

 rouico-cylindricis; pro-, meso- et metanota puuctulata; abdomen glabrum, minute punctulatum ; J* segmentis 

 apicalibus lateribus convexis et rugulosis; fordpis bracchia subcontigua, valida, apice attenuata et incurva. 



Large; deep black, head dark reddish chestnut. 



Antennae with (?) Segments, deep reddish blac"k; 3 not so long as in other species; 4 and 5 together 

 equal in length to 3, conical; the rest longer, passiug from conical to cylindrical. 



Head smooth, deep chestnut, almost black. 



Pronotum subquadrate, punctulate, slightly broader posteriorly than anteriorly, the lateral raargins 

 exceedingly narrowly reflexed and reddish. 



Meso- and metanotum ample, flat, deep dull black, and punctulate. 



Feet dirty yellow, with yellow pubescence; femora and tibiae rather short. 



Abdomen dark reddish black, entirely punctulate; in the ^ dorsal segraents at the sides gently convex 

 in the basal segraents, distinctly convex in the apical Segments; the convex part distinctly rugulose in the 

 apical Segments. 



Venter shining, much more finely punctulate. 



Last dorsal segment, ample, subquadrate, with rows of exceedingly minute punctulations. 



Forceps with the branches short, very stout, and triquetre at the base, nearly contiguous, gently curved 

 inwards and upwards, attenuate apically, not toothed. 



Hab: — Nyassa (one pair in my coUection, brought from a German dealer). 



I describe this species here in order to compare it with the allied species from Kilimandjaro; in the 

 structure of the sides of the apical dorsal abdominal segments it approaches A. lacfa, as also somewhat in the 

 shape of the forceps, but it is much larger and of a stouter build. The female resembles the male in every 

 respect except that the convexity of the sides of the abdominal segments is far less pronounced, and they are 

 less rugulose; is also the case in A. laeta.
