On Some Species of Hesperia (Lepid., Hesperidae.). 



By WM. BARNES, M.D. and A. W. LINDSEY, Ph.D., 

 Decatur, Illinois. 



In the Bulletin dc la Socicte Icpidoptcrologiqitc dc Geneve, 

 vol. IV, pp. 96-107, Dr. Reverdin considers in his usual pains- 

 taking way the North American species Hesperia s\richtns, 

 describing a new form, fmnosa. In the same paper he gives 

 the name syrichtides to the Central American species which 

 has been called orcus Cram, by some writers. Dr. Skinner, in 

 ENTOMOLOGICAL NEWS for December, 1919, p. 297, calls atten- 

 tion to this paper and adds some interesting information regard- 

 ing the types of wontiragus Reak. 



It was our pleasure during the summer of 1919 to investi- 

 gate these names as thoroughly as possible, and only the lack 

 of definite information on the actual identity of syrichtus pre- 

 vented an earlier publication of our conclusions. Fabricius 

 stated the locality of syrichtiis in the original description (Syst. 

 Ent.. 534, 1775) as America, and Butler (Cat. Fab. Diurn. 

 Lep. B. M., p. 280, 1869) applied the name to specimens from 

 Honduras. This led us to the conclusion that the name might 

 properly refer to syrichtides, rather than to the more northern 

 form, and specimens were sent to the British Museum for com- 

 parison with the specimens mentioned by Butler. An answer 

 recently received from Mr. N. D. Riley, who has kindly ex- 

 amined all the material in his care, informs us that these speci- 

 mens are no longer to be found, and that the two species are 

 mixed under the name syrichtiis in the. museum series. He 

 further states that our North American species alone is repre- 

 sented by specimens from Honduras, among a series from 

 Mexico to Costa Rica, while of the other form specimens from 

 Panama and various parts of South America are in the collec- 

 tion. Dr. Reverdin, in his paper, adds Brazil to the range of 

 both species, and Mexico to that of syrichtides, in addition to 

 other records. From the aggregated data it would thus seem 

 impossible to arrive at any conclusion based on distribution, 

 and we can only retain syrichtus Fall, as it has hitherto been 

 used.
