4S Mr. M. Burr — Notes on the Forficularia. 



This species closely resembles F. walker i, Kirby, from 

 Hong Kong in size and appearance. It differs in the form 

 of the forceps : when seen from above, the branches are 

 laterally undulating in that species ; in this they are 

 simply and gently incurved : the denticulation is more 

 pronounced in F. loalkeri] the abdomen is finely punctulate 

 in F. walkeri, granulose in this species ; finally, the slender 

 abdominal spines are quite straight in F. loalkeri and gently 

 recurved in this species. 



I have pleasure in dedicating it to its discoverer, Mr. Ed- 

 ward Jacobson, of the Hague. 



Labia nigroflavida, Rehn. 

 Description of the Male. 



Agrees perfectly with Rehn's description, with the excep- 

 tion of characters which are purely sexual. 



The last dorsal segment is ample, rather tumid, nearly 

 square, smooth, with a few shallow punctulations ; the median 

 sulcus is faint ; depressed posteriorly ; the posterior margin 

 itself truncate, with a row of minute tubercles above; on 

 each side over the roots of the forceps there is a pair of 

 elevated longitudinal ridges. 



Penultimate ventral segment large, covering the last 

 segment, obtusely rounded, slightly emarginate at the apex 

 itself. 



Pygidium not visible. 



Forceps with the branches remote at the base, triquetrous, 

 stout, and dilated at the base itself, this dilation terminated 

 by a short sharp tooth in the inferior margin, then suddenly 

 attenuated and excavated along the inner margin for nearly 

 half their length ; at this point thickened to a sharp conical 

 tooth, where the curvature is lessened ; beyond this point 

 gently incurved, the apex sharp and crossing. Seen from 

 above the branches appear nearly straight, gradually con- 

 verging. Viewed from the side gently sinuate downwards, 

 then upwards. 



Long, corporis 10'5 mm.
