Geometridae 



Genus LYCIA Hubner 



(i) Lycia cognataria Guenee, Plate I, Fig. 17, larva; Plate 

 XLIV, Fig. 13,6. 



Syn. sperataria Walker. 



This is a common species in the Atlantic States. The larva 

 depicted on the plate is brown. In every brood there are many 

 specimens of the larvae which are green, and some are even yel- 

 lowish. The moth has in the vicinity of Pittsburgh latterly shown 

 a fondness for ovipositing upon imported rhododendrons, and the 

 caterpillars have proved troublesome. 



Genus NACOPHORA Hulst 

 (i) Nacophora quernaria Abbot & Smith, Plate XLIV, Fig. 



14,?- 



The species is not as common as the last, but is not rare. It 

 has the same habitat, being a native of the Appalachian subregion. 



Genus APOCHEIMA Hubner 



The genus is found in the boreal regions of both hemispheres. 

 Only one species occurs in our fauna. 



(i) Apocheima rachelae Hulst, Plate XLIV, Fig. 12, $. 

 (Rachel's Moth.) 



The moth is found in Montana, Assiniboia, and northward to 

 Alaska. 



Genus CONIODES Hulst 



(i) Coniodes plumigeraria Hulst. (The Walnut Span- 

 worm.) 



In recent years the groves of English walnuts in southern Cal- 

 ifornia have been found to be liable to the attack of a span-worm, 

 which previously had been unknown or unobserved. The trees 

 had up to that time been regarded as singularly immune from the 

 depredations of insect pests, and considerable alarm and appre- 

 hension were felt when it was found that a small caterpillar had 

 begun to ravage them. The insect feeds also upon the leaves of 

 various rosaceous plants, and upon the oak. The taste for the 

 foliage of the English walnut has evidently been recently acquired. 



An excellent article upon these insects was published in 1897
