GEOMETRID NEWS— DESCRIPTIONS OF TWO NEW 

 HYDRIOMENAS. 



BY L. W. SWETT, BOSTON, MASS. 



Hydriomena he?ishawi, nov. sp. 



Palpi short ; expanse of wings 35 mm. 



Colour of fore wings light ash-gray, speckled with black atoms ; the 

 space between the basal line and body of the same colour. Basal line 

 bent outwardly from body at vein Sc. (Smith's Glossary), then curved 

 slightly inwardly toward body, the curve ending quite a distance out on 

 inner margin with a black dash ; mesial space gray, with black atoms ■' 

 median band black and irregular ; intradiscal line running from costa to 

 inner margin almost diagonally, with irregular curves between the veins ; 

 mesial or discal space with a faint spot ; extradiscal line black, starting in 

 a dash at costa, then curved outward with irregular points, as in autumn- 

 alis ; outer margin pale gray with black atoms, the usual watery black 

 band curved more regularly than in autumnalis. Fringe long, pale gray, 

 with double points at base of fringe. 



Hind wings pale gray, with the usual two faint extradiscal bands. 



Beneath, the discal points on the fore wings are represented by two 

 pale dashes, the lines above showing through faintly. The dots on the 

 hind -wings beneath are round ; beyond, the two pale gray lines show 

 through from above. The fringe is long and pale ash-gray, as above. 



Type, I $ , Nevada, Museum of Comparative Zoology, Cambridge, 

 Mass. I take pleasure in naming this species after my kind friend, Mr. 

 Samuel Henshaw, who has assisted me much in my work on the 

 Hydriomenas. 



This species resembles slightly H. quinquefasciata Packard. 

 (To be continued.) 



Extensive infection of the San José scale has been discovered on trees 

 in the southern part of Wisconsin by Professor J. G. Sanders, of the Univer- 

 sity of Wisconsin. Professor Sanders, who is also State Nursery Inspector, 

 reports that steps are being taken to control the pest and prevent its 

 spreading beyond the area affected already. — \Scie7ice.
