70 THE CANADIAN ENTOMOLOGIST. 



broader than long, the first a little the sliorter; third about as broad as 

 long. Prothorax with a very strong keel running to tubercles ; meso- 

 thorax evenly and very closely punctured ; scutellum very finely and 

 closely punctured at the sides, the disc with a pair of small smooth 

 sublateral areas, a yellower green than the surrounding parts ; post- 

 scutellum very minutely punctured in the middle, coarsely subreticulate 



at sides ; metathoracic enclosure distinct, shining, very blue, with numer- 

 ous longitudinal ridges ; sides of metathorax and the ill-defined truncation 

 very closely punctured. Pubescence of head and thorax scant and pale, 

 rather conspicuous on upper part of face, the hairs beautifully plumose. 

 Tegulfe piceous, the outer edge hyaline, the base greenish and with 

 niinute punctures. Wings dusky hyaline, stigma dark brown, nervures 

 piceous, second submarginal cell much higher than long. Legs black, 

 with thin white pubescence, cox?e in front, and anterior femora behind, 

 metallic blue-green ; anterior tibiae in front, and anterior tarsi, rufescent, 

 remaining tarsi more or less rufescent within ; hind spur of hind tibia 

 minutely ciliate. Abdomen with first segment having rather large, 

 tolerably close punctures, and a small purple spot on each side ; second 

 segment with the punctures conspicuously smaller and closer ; third with 

 them still smaller, and much feebler ; remaining segments with them 

 minute and feeble. No hair-bands, but short pubescence, shining 

 brilliant silvery in certain lights. 



Hah. — San Rafael, Vera Cruze State, last of June; collected by Prof. 

 C. H. T. Townsend on plant No. 31, which Dr. Rose says is a Cordia, 

 probably C. ferrnginea. The coloration of this beautiful insect is 

 singularly like that of some new species of Vohicclla taken by Prof. Town- 

 send at the same locality, especially in the effect of the pubescence and 

 metallic colours on the abdomen. It resembles somewhat A. urania, 

 Sm., and A. feronia, Sm., from Brazil. On the same flowers, at the same 

 time and place as A. Townsendi, Prof. Townsend took both sexes of a 

 lovely Teinnosoma, either T. sviaragditium or possibly a new species, 

 since it seems to differ from Smith's description, being larger, the head 

 hardly quadrangular, the wings darker, etc., but it differs so little that it 

 will be advisable to call it smaragdinuin, Sm., var., until comparison of 

 specimens can be made. 



Plant No. 4 (see p. 6) on which A. Binghavii was taken, has been 

 identified by Miss Vail as Calopogonuim ccerulenm (Benth.) Britt.
