hind angles of the prothorax acute, while in scarabceoides they are obtuse. 

 They are generally not as brightly coloured as scarabceoides, though some 

 of the varieties approach certain varieties oi scarabceoides. 



The colour is black ; prothorax and elytra generally with testaceous 

 margin. Elytra near apex with a variable, transverse reddish-yellow fascia 

 across suture of irregular outline and sometimes with a red humeral spot. 



The transverse sub-apical fascia is sometimes very indistinct and often 

 absent. 



GEOMETRID NOTES. 



A New Eupithecia. 



BY L. W. SWETT, BOSTON, MASS. 



Eupithecia Chag?ioni, nov. sp. 



Expanse 22 mm. Palpi long. Head white or grayish between 

 antennae. Wings light reddish ash in colour, darker towards outer 

 margins. Fore wings light ash, with reddish brown shadings. Basal 

 band narrow and black at costa about 2 mm. from body, whence it is 

 curved back to base. Between the basal line and intradiscal are a few 

 dashes. The intradiscal line is represented on costa by quite a large 

 triangular patch bent towards discal spot, and from this patch runs a fine 

 line accentuated on the veins to inner margin. Then a clear mesial space, 

 in which the black discal spot stands out; beyond on costa the extradiscal 

 line is also represented by a triangular patch, from which a hair line bends 

 outward opposite discal spot, then inward scalloped on every vein to inner 

 margin. Beyond extradiscal line is a pale band, following the same course 

 about I mm. wide, with a black hair line running through it to inner 

 margin. Beyond this for 3 or 4 mm. the wing is shaded heavily with 

 reddish brown, with a trace of a faint, light, irregular line running to inner 

 margin. The fringe is quite long and grayish, with intervenular dots. 



The hind wings are full and rounded, as are the fore wings, and of 

 the same colour, only darker. Several faint wavy lines may be discerned 

 running across the wings below discal spot, which is round and black. 

 Beneath, fore wings as above, only the extradiscal is wider and blacker, 

 and the pale band beyond is clearer than above ; discal spots show on all 

 wings. Hind wings, three prominent wide dark bands on basal and two 

 beyond discal spot, which are slightly bent outward opposite discal spot. 

 This is a very distinct species and not easily confounded with any other ;
