A New Geometer from Colorado. 



By Edw. L. Graef. 



Lithostege virginata, spec. nov. 



Female; primaries dead pearl white; a slight transverse anterior band 

 of blackish rays. Transverse posterior heavier, especially near the median 

 cell, and slightly covered with greyish atoms. Fringes white, checkered 

 with black at the veins; a faint sub-basal line of blackish. 



Hind wings uniform light smoky ash; fringes long. 



Beneath, all the wings smoky ash, the primaries somewhat darker, 

 especially on the costa. The transverse posterior appears through faintly, 

 and on the costa forms a black spot. A sub-apical patch of white enclos- 

 ing a smaller one of ground color. Fringes of primaries as above, of sec- 

 ondaries ash color. Expands 30 mm. 



Hab. Colorado. From one female in Coll. Edw. L. Graef. 



A Hint for Collecting. 



Mr. W. Petersen writes in Stettiner Entom. Zeitschrift March, 

 1 88 1 page 245 in an article, "A few words about the occurrence of Hetero- 

 ceri in tropical climates" that common baits with sugar etc. did not work, 

 but that he found by chance that fish partly decayed, hung up to dry, at- 

 tracted an immense number of Macros and Micros, that he collected 

 thereby on one day 600—700 specimens, that he could have taken many 

 more, but he took only the perfect ones. F. G, Schaupp. 



On Collecting Elmidae. 



Pieces of wood placed in running water fastened to the ground, 

 or weighed down by stones on rocky ground to prevent their being washed 

 away, prove very attractive breeding places for Elmidae. Brooks running 

 through woods are best suited and pine or cedar should not be used, as it 

 takes a long while before insects settle on it, very likely on account of the 

 strong odor. Take the wood, examine it very carefully in the sun, as 

 many of the Elmis are very small and will not be seen, unless they move 

 out of the crevices and cracks, when exposed to the warmth and light. 



Last year I collected in the vicinity of New York City, the following 

 Elmidse in the manner above described, Elmis bivittatus, Lee, 4 notatus, 

 Say., ovalis, Lee, nitidulus, Lee, pusillus, Lee, crenatus. Say., bicari- 

 natus and very likely a new species allied to the last; Macronychus glab- 

 ratus, Say. and Ancyronyx variegatus, Germ., (found from April to Dec.)
