Head and face dingy yellowish, sometimes brownish. Antennee distinctly annu- 

 lated. Pronotum fuscous with a nari'ow median longitudinal dingy yellowish line, 

 whicli expands on the meso- and meta-notum. Legs whitish-yellow ; terminal 

 tarsal joint blackish. Anterior wings oval, pale grey, the dorsal and apical margins 

 somewhat darker (but much less so than in the last species), the nerrures regularly 

 and closely spotted (with angulate markings as in the last species), but often (not 

 always) without spots in the area between the two gradate series, these gradate 

 series placed widely apart, irregular and divergent : the fuscous markings are strong ; 

 there is a series of small spots along the radius, a large sub-basal spot on the con- 

 striction between the cubiti often continued upward to the radius, one or more spots 

 on the lower cubitus, often connected with an irregular fascia on the inner gradate 

 series, and there is a second fascia on the outer gradate series (as these fasciae follow 

 the nervules they vary in direction as the nervules vary) ; pterostigmatic region 

 elongate, subopaque, yellowish, scarcely reddish. Posterior wings pale grey, irides- 

 cent, pterostigmatic region strongly defined, the costal and transverse nervules, and 

 part of the longitudinal nervures, blackish. Expanse, 12 — 16 mm. 



In the (J the apical dorsal half of the abdomen is not so strongly clothed with 

 hairs as in stigma. The appendages are formed after the same plan, but the lower 

 branch of the fork is longer (as long as, or longer than, the upper), and furnished 

 internally at the apex with a few stout, straight, spiniforra hairs : as a rule the 

 branches of the opposing forks are less strongly interlocked than in stigma, the 

 opposing points often scarcely more than touching (but much depends upon drying). 



This form most approaches stigma, but may be distinguished by 

 the neural character mentioned above, the pale thoracic line, the more 

 decided wing markings, and by the small, yet evident, difference in the 

 appendages. 



In Britain it is rare, and usually taken only singly, and of small 

 size. On the continent of Europe it is wide-spread, and apparently 

 often abundant. I have it from Belgium, Switzerland, Savoy, the 

 Pyrenees, Vosges, Schwarzwald, Bohemia, Sweden, Finland, &c. 



A North American insect in my collection from Delaware can 

 scarcely be other than a $ of this species or race. 



The specimens of " pini " in Stephens' collection are a mixture of 

 my pi7ii and stigma ; there is no MS. label, but a specimen with a 

 printed label is the insect now under consideration.
