Notes upon various species of the Ennominae 



By Geo. D. Hulst. . 



Oxydia vesuliata Cr. This S})ecies has been taken in Soulhern 

 Florida. The specimens differ in no respect from those received from 

 Brazil. It is the largest Geometer of our fauna, expanding 75 mm. 



Urapteryx politiaria Cr. To specimens of this taken in Floridii, 

 Mr. Grote gave the varietal name ol floridata. The Florida specimens 

 seem to vary very little, and where a stretch of sea or a range of mount- 

 ains intervenes slight differences may be of even specific value. But 

 specimens of U. politiaria from Brazil are taken in numbers, the exact 

 counterparts of the Florida form. 



Ripula virginaria Hulst. One of the most beautiful of Geometers, 

 and the first of its genus in our country. 



Eutrapela transversata Dru. This species is very variable in the 

 color and shape of its wings. It undoubtedly includes in its reach not 

 only the many forms given nam^ by Guenee and Walker, but as well 

 the species Guenee called C. incurvata and C. tetragonaia. The only 

 individual difference in the latter is the cross striations at the base of the 

 tail. The cross line is found in every variation. 



In all collections that have come under my notice, the ochreous form 

 IS labelled var. goniata Guen. According to Dr. Packard, goniata is the 

 fawn colored form, and is a synonym of transversata Dru. The variet\- 

 name of the yellow form is transpositata Wlk. 



Specimens from the South are generally less angulated than those 

 from the North, and are often of the variety incurvata Guen., having no 

 angle on outer margin of fore wings. 



Eutrapela clemataria Ab. & Sm. There is considerable variation in 

 this insect, especially in the female. One form, generally from the South, 

 is lighter in color, with the apex of fore wings more pointed and very 

 much extended. This is, I believe, the true E. ckmataria Ab, & Sm. 

 The darker form is var. Iransducensata Wlk. This species also varies 

 very much in the amount of undulations on the outer margins. Gener- 

 ally very prominent, the undulation is sometimes hardly perceptible. 



Tetracis truxaliata Guen. Differs much in the size of specimens, 

 ranging from 30 to 60 mm. 



Tetracis cervinaria Pack. This is one species in my opinion with 

 T. aurantiacaria Pack., the former being the (^, the latter the 9 form. 

 The sexes are much more distinct than is usual in this subfamily. The
