there are others in which no trace of them whatever can be found. 

 The species of Forcinella also (that is, those presenting no abdominal 

 plications) vary to a considerable degree in the angular production 

 of the sides of the abdominal segments, some in my possession sur- 

 passing in this particular the species maritima ; so that it becomes 

 certain that these distinctions are valueless ; and as no others have 

 been found we must group these apterous forms in a single genus, 

 whose facies is then homogeneous. Forcinella, as the older name, 

 would then absorb Brachylabis, were it not in its turn preoccupied, 

 as we shall see, by Anisolabis, It is possible, however, that angulifera 

 or chilensis, or both, may be generically distinct from the other spe- 

 cies placed in the same group by Dohrn, and in that case Brachyla- 

 bis could be retained. I have seen neither of them. 



CARCINOPHOEA. 



This name (/.ap/.tvoc, (fipo)) is proposed for the Peruvian species 

 which I described a few years ago under the name of Clielidura ro- 

 husta. The genus is allied to Anisolabis, but has fewer joints in the 

 antennae, and the first joint of the same very long, besides perfectly 

 formed tegmina. The head is subtriangular, much longer than broad, 

 somewhat broader than the pronotum, tumid, the posterior angles 

 broadly rounded; eyes pretty large; antennie 13-jointed, the first 

 joint as long as the space between the antennae, slender, increasing 

 but little in size apically, second joint no longer than broad, globular, 

 third three times as long as broad, fourth and fifth equal, together as 

 long as the second and third combined, the others submoniliform, 

 subequal, about as long as the third. Pronotum flat, a little longer 

 than broad, tapering slightly, produced apically with well rounded 

 hind border. Tegmina as long as the pronotum, squarely docked, the 

 sides forming an acute angle with the dorsal area; wings wanting. 

 Legs long, compressed, the middle nearly as long as the 'hind pair, 

 the middle joint of tarsi minute, but produced beneath the apical 

 joint, not lobed. Abdomen stout, the last segment of ? very large, 

 above subquadrate, below almost as long a^ the rest of the abdomen 

 and triangularly produced ; sides of second and third dorsal segments 

 with but slight plication. Forceps stout, short and simple in the ?. 

 The female only is known to me, and the single species comes from 

 the Peruvian Andes.
