1886.] 279 [Hagen. 



dian black dorsal line on the last segments ; male genitals with a 

 lower, very large and very concave lobe, seen from below oblong 

 (in one ovoid) and very pilose ; two parallel yellowish hooks orig- 

 inating before the base of the lobe are similar to a curved and 

 pointed knife ; the base is broader, short with a very marked dor- 

 sal knee, followed by a straight part, which ends in a strongly in- 

 curved and sharply pointed apex ; abdomen of female similar, apex 

 compressed, last segment very short, blunt. 



Hab. I have before me 3 $ and 7 9 ; from Umea, Lapland, lo- 

 cality not recorded before ; from Eastern Prussia, Insterburg ; 

 from Pommerania ; from Silesia, type of Schneider ; Glatz ; from 

 Meseritz, Zeller, Sept. 11 ; from Austria, from Ischl ; from Up- 

 per Karinthia, Zeller July 6. Wallengren quotes localities from 

 southern Sweden up to Jamtland ; very common in forests June 

 to August ; in England common throughout the summer, M'Lach- 

 lan ; at Lyon, France, rare, Villers and Rambur ; Russia, St. Pet- 

 ersburg, 0. Sacken ; Utto, Zurich, Switzerland, 2100 feet on 

 beeches only once found, H. semireticulatus Bremi. 



Though the type of Linnaeus no longer exists, and his descrip- 

 tion is very short, it has unanimously been accepted to belong to 

 this species, first by Villers and later by Schneider. The bands 

 on the wings variable, sometimes nearly disappearing. The spec- 

 imen from St. Petersburg is the largest and most variegated seen 

 by me. 



2. Micromus montamis new spec. 



Long. c. al., 11-12. mm. ; exp. al. 21-23 mm. 



I have for a long time been uncertain, if M. montanus is only a 

 race of M. paganus ; nevertheless the different shape of the geni- 

 tals of the male and some additional characters have decided me to 

 consider M. montanus as a different species. 



Shape, size, color and pattern as in M. paganus. The hooks of 

 the male are longer and much thinner, cylindrical, sharp spines, 

 triangularly dilated at base, without the basal knee of M. paganus, 

 but more curved before tip ; the lower concave lobe more square. 

 The occiput is not elevated ; wings similar, but the internal oblique 

 band reaching always the front margin ; the gradate veins mostly 

 darker, blackish. 



Hab. Natick, Mass. ; White Mts., N. H., July, 1875, Morrison. 

 I have 2 $ and 5 <? before me.
