at tip. Fuscous markings and cloudings are also present in varying degree on the 

 lateral lobes of the pronotum and along the margins of the median dorsal pale 

 stripe, on the vertex and occiput, the meso- and metapleura, and the geniculations 

 of the hind femora. The anterior and middle femora are ferruginous.

Nearly allied to B. obesa, differing from that species in its smaller size, the 

 structure of the pronotum, the less upturned end of the abdomen, and in the form 

 of the supra-anal plate of the male. In obesa this plate is as wide as long, in com- 

 pacta it is distinctly longer than wide. The lateral carinae of the pronotum are 

 equally as distinct or even better developed than in obesa and less irregular in 

 course, in obesa being broken or angulate at the anterior and middle sulci, forming 

 two pairs of lines diverging posteriorly while in compacta they form essentially but 

 one pair of divergent lines though somewhat sinuous ( 9 ) or subangulate ( J*) at 

 the crossing of the sulci.

LIFE HISTORIES OF NORTH AMERICAN GEOMETRIDAE. — XLI. 



BY HARRISON G. DYAR, WASHINGTON, D. C. 



Erannis tiliaria Harris. This well-known larva has been frequently referred 

 to in economic entomological literature, but I find no description of all the stages. 

 Harris gives a good general account of the habits ; Jaeger, Coquillett, Saunders,. 

 Fernald and Lugger have also written on it. The species has been bred at the 

 Department of Agriculture and all the larval stages preserved and Mr. H. D. 

 Merrick has sent me eggs from New Brighton, Penn., laid Oct. 31, which hatched 

 April 6, the following year. 



Egg. Elliptical, flattened on two sides, soft-shelled, concave ; no flattening on micropvlar 

 end but the other end smaller and depressed; outline nearly regularly elliptical. Reticula- 

 tions large and coarse, a little transversely elongate, the areas concave. Size .6 X .5 X -3 

 mm. Color ocherous yellow, dark gray just before hatching. 



Stage I. Head rounded, scarcely bilobed, dull, sordid, reddish luteous, held obliquely 

 erect, vertex dark, eye dull black ; width .3 mm. Body rather robust, uniform, ends rounded.
