Spilogona acuticornis Malloch. 
This species is very closely related to surda Zetterstedt. It 
has, however, a distinct dorsocentral vitta between the spots on 
abdomen which is absent in surda, the frons is as wide as eye at 
middle as seen from in front, the apex of each process of fifth 
abdominal sternite is much more produced, and though, like 
surda, it has fine long bristly hairs on basal half of postero ventral 
surface of hind femur these are more numerous than in the latter 
and not in a single series. The crossveins of the wing are more 
widely separated than in surda. 
One male, Machias, Me., July 17, 1909. 
These notes are drawn from a comparison of the above spe- 
cimen and an authentic male of surda sent to me along with 
hrunneisquama and contractifrons by Mr. O. Ringdahl from 
Sweden.
