NOTES ON SOME GENERA OF OPHIONIN^ WITH 

 TOOTHED FEMORA. 1 



By Charles T, Brues. 

 Eiphosotna Cresson.^ 



This genus was first proposed by Cresson (Proc. Ent. Soc. 

 Philadelphia, Vol. 4, p. 52, 1865) for four Cuban species. Since 

 then five others have been described, one from Brazil and the 

 others from Mexico and the southern United States, 



The addition of the species here described extends considerably 

 the northern range of the genus which has not been hitherto 

 found north of Missouri. 



Omitting the Brazilian species, the others may be separated 

 by the following dichotomy. 



Key to the Species of Eiphosoma. 



1. Mesothorax with two yellow oval spots anteriorly on its middle 



lobe; metathorax principally black E. pyralidis Ashm. 



Mesothorax either yellow with black stripes or black with elon- 

 gate yellow stripes; metathorax prevailingly yellow or at least 

 with three yellow stripes 2 



2. Metathorax with only a median black line, its anterior suture 



sometimes black 3 



Metathorax with lateral black markings additional to the median 

 spot or line 6 



3. Mesopleura with a black spot or oblique line 4 



Mesopleura entirely yellow; wings entirely hyaline, areolet 



present E. vitticoUe Cress. 



4. Posterior tibiae entirely honey-yellow; areolet wanting 



E. nigrovittatum Cress. 



Posterior tibiae black, except for a median pale annulus 5 



5. Large, length nearly 25 mm. Wings entirely hyaline 



E. mexicanum Cress. 



Smaller, length 12 mm., wings infuscated somewhat at the tip 

 E. septentrionale sp. nov.

'(Changed to Xiphosoma by Sz^pligeti in the Genera Insectorum, fasc. 54, p. 4, but I believe 

 that the original orthography should be adhered to, and not changed for mere philological 

 reasons.)
