Spécimen typicum hujus speciei a. 1882 in Museo Berolinensi examinabam, cum sin- 

 gularem femorum anticorum ejus structui'am animadverti. Unica specimina quoniam es illo 

 museo foras non mittuntur spectanda, cum hane speciem non ipsi potuerimus describere, 

 Steini adtulimus descriptionem. (0. M. R.). 



Species incei'ta. 

 Nabis concinnus (Walk.) 



„Faem. Nigra, pilosa; caput et prothoi'a.K aeneo-nigra; caput longi-conicum, protho- 

 racis lobo antico aequilongum; antennae capite et prothorace ad unum paullo bieviores ; ab- 

 domen basi subtus luteum; pedes lutei, femoribus ^igricante unifasciatis ; corium testaceo 

 pallido trimaculatum ; membrana apice pallide testaceo. 



Female. Black, smooth, shining, hairy, fusiform. Head and prothorax aeneous-black. 

 Head elongate-conical, as long as the fore lobe of the prothoras; ante-ocular part a little 

 more than twice as long as the post-ocular. Antennae setulose, a little shorter than the head 

 and the prothorax together; first joint as long as the ante-ocular part of the head; second 

 fuU twice as long as the first; third shorter than the second; fourth as long as the second. 

 Fore lobe of the prothorax fuU twice as long as the hind lobe. Abdomen luteous towards 

 the base beueath. Legs luteous, stout; femora with a blackisli band. Corium with three pale 

 testaceous spots; first basai, costal; second transverse, in the disk; third apical. Membrane 

 pale testaceous at the tip. Length of the body 3 '/2 hues. 



- The wholly black prothorax of this species and the wholly red prothorax of P. loncji- 

 ceps distinguish them from P. perpulchra.
