 with black maculations at joints. Beneath, thorax and abdomen with lighter 

 coral, the latter having black segmentary stripes. Legs blackish. Primaries 

 black, with the following maculations in straw-yellow; a broad horizontal line 

 running parallel with inner margin from base to outer margin and forking at 

 anal angle. Between this line and inner margin, appending to the former, 

 three irregular spots. Two transverse lines starting from costa, joining and 

 resting on horizontal line, thus enclosing discal spot. Between anterior trans- 

 verse line and outer margin the usual zigzag line from costa to horizontal 

 line. A few irregular dots on costa between base and interior transverse

 Expanse of wings 30 mm. Length of body 9 mm. 



Hab. — Golden, Colorado. Types, two males; coll. B. Neumoe- 

 gen; caught by Mr. D. Bruce. 



This insect comes near E. cadaverosa Grote. It is easily recog- 

 nized by its conspicuous costal lines. E. cadaverosa is found in 

 Cuba and Texas, whilst this is the Colorado representative.
