PARISOLABIN^. 

 Pseudisolabis elegans new species. PI. XVI, figs. 2, 3. 



The present species is related to P. hurri and P. tenera, easily 

 separable in the male by the much more elongate and evenly curved 

 forceps. It agrees more nearly with tenera in form, coloration and 

 antennal joints, but with hurri in the form and contour of the ultimate 

 dorsal abdominal segment and proportions of the tarsal joints. 



Type: cf ; Kulu, Kangra, India. (M. M. Carleton.) [Museum of 

 Comparative Zoology.] 



Size rather small ; form compact, greatest width mesad on abdomen. 

 Dorsal surface shining, of head and pronotum smooth with hardly 

 any hairs, of abdomen exceedingly finely pubescent, each minute, 

 microscopic hair springing from a minute, microscopic pit, proximal 

 segments with a few small bristles laterad. Head with sutures 

 subobsolete, a few very feeble depressions indicated meso-caudad 

 on the occiput. Antennae with third joint elongate, distinctly longer 

 than sixth, (in the majority of specimens longer than any other 

 excepting the first. The fourth joint is normally wider than long, 

 but varies to appreciably longer than wide.) Pronotum wider than 

 long, rectangular, with angles sharply rounded; surface weakly 

 convex with a feeble medio-longitudinal sulcus, which is obsolete 

 caudad; concave narrowly laterad, the concavity feebly extending 

 mesad at the juncture of the prozona and metazona, which are fused 

 without further demarkation; lateral margins cingulate. Mesontum 

 and metanotum very short. Dorsal abdominal segments simple, 

 with straight caudal margins, which are not produced laterad and 

 are broadly convex latero-ventrad; ultimate segment very short, 

 fully four times as wide as long, slightly depressed and declivent 

 distad in mesal section, with a feeble medio-longitudinal sulcus; 

 caudal margin truncate, feebly rotundato-angulate produced above
