unknown. If it is found to differ the name will be resurrected 

 from the synonymy. 



Genus LEMMAMYIA, new genus 



Type species : Limatus methysticiis Dyar & Knab. 

 Only a single species is autoptically known to me. 



Lemmamyia methysticus Dyar & Knab. 



Limatus metliysticus Dyar & Knab, Smith. Misc. Colls., Quart. 



iss.. Hi, 266, 1909. 

 Limatus methysticus Howard, Dyar & Knab, Mosq. No. & Cent. 



Am. & W. I., ii, pi. 2, fig. 5, 1912. 



I have the species only from Costa Rica and Panama, but it 

 must be more widely distributed. Dendromyia asidlepta Theo- 

 bald (Mon. Culic, iii, 315, 1903), from British Guiana appar- 

 ently comes close and may be the same. Mr. Jennings bred 

 methysticus from larvae in a palm-spathe lying on the ground. 



I think this will prove to be the same as Wyeomyia hem- 

 isagnosta Dyar & Knab (Journ. N. Y. Ent. Soc, xiv, 230, 1906). 

 That species was described from larvae in cacao shells from 

 Salvador and Costa Rica ; methysticus from captured adults 

 from Costa Rica. The association seems entirely probable and 

 the breeding habits are consonant. It is to be noted that the 

 species breeding in dead tissues, such as cocoanut-husks and 

 bamboo, are widely distributed, whereas those breeding in 

 living tissues, such as Bromeliaceae, are restricted in distribu- 

 tion. Therefore, I think this a widely distributed form and 

 that asullepta Theobald will prove the earliest name, with hem- 

 isagnosta D. & K. and methysticus D. & K. as synonyms.
