THE CANADIAN ENTOMOLOGIST. 32 



Q 



unio. Abdomen red on the sides ; venter pale. Antenna; 

 simple. Front not tuberculate. One female from Assumption (So. 

 America, coll. Consul Mangels) in Mus. Bremen. 



This species is perhaps a little smaller than grata, very different from 

 both N. American species by the darker creamy shade, not white, of the 

 median field of primaries, by the red colour of hind-wings and under- 

 surface, by the red abdomen and unhanded secondaries. It is, in shape 

 of primaries and in their style of ornamentation, nearer grata than unio. 

 The discovery of a South American representative of grata, with un- 

 handed secondaries, is interesting. The latter character is only found in 

 E. Stae. Johannis, where the yellow hind-wings are without band. 

 Although on this account alone the specific value of the latter may not 

 be adequately defended, yet the probabilities in favour of this view may be 

 considered to become somewhat heightened in view of the discovery of 

 the South American species. The terminal bands of the hind-wings in 

 grata and unio are decidedly characteristic, and one is unprepared for 

 their absence in Stae. Johannis, unwilling to consider so marked a modifi- 

 cation merely varietal. 



The following is a list of the Eudriince : — ** 



Eudryas, Boisd. Copidryas, Grt. 



i. unio, Hiibn. 5. Gloveri, G. 6° R. 



var. brevipennis, Stretch. 6. platensis, Berg. 



2. grata, Fabr. 

 assimilis, Boisd. 



ab? Stras. Johannis, Walk. Euscirrhopterus, Grt. 



3. Cypris, Grt. 7. Poeyi, Grt. 

 Ciris, Grt. disparilis, H.-S. 



4. Wilsoni, Grt. 



The North American Agaristidic apparently fall into two sub-families, 

 the Eudriince, above catalogued, and the Alypiince, containing Alypia, 

 Androloma, Pseudalypia, Edwardsia, and Psychomorpha. The Castnii- 

 dce are apparently not represented in the North American fauna. The 

 Zygcenidce are now restricted by Dr. Packard so as to include Horama, 

 Burtia and allies, with Ctenucha and Scepsis in one sub-family group, 

 while Procris, Harrisina and their allies fall into the typical sub-family, 

 being more intimately related with the European Zygoma, a genus not 

 represented with us. From this it will appear that a belief in the stability 

 of the rearrangement of the Zygamidce in the Philadelphia List will 

 probably prove illusory. The genus Oeta, Grt., should be removed to 

 the Tineidat, as indicated by Zeller. 



**For a list of our species consult also Papilio I., 177. I have never seen a Californian 

 specimen, and am quite doubtful as to brevipennis being a variety of unio. Stretch's 

 figure and description were made from an imperfect example. The Cuban E. Poeyi was 

 subsequently described by Herrick-Schaeffer as Heterandra disparilis ; on comparison 

 of the dates of issue of the two publications, which appeared nearly at the same time, 

 the Philadelphia paper has priority.
