INSKCUTOR INSCITI^ MENSTRUUS 136 



(Mosq. No. & Cent. Am. & W. I., iii, 121, 1915). In addition 

 the females of intonca D. & K., circiimcincta D. & K., and 

 ccrnonus H., D. & K. are indistinguishable from this in color- 

 ation, which does not add to the ease of identifying Theobald's 

 name. 



Genus LIMATUS Theobald 



Limatus Theobald, Mon. Culic, ii, 349, 1901. 

 Simondella Laveran, C. R. Soc. Biol., liv, 1160, 1902. 



Type species : Limatus durhamii Theobald. 



Eliminating methystkus, which I place in the genus Lem- 

 mamyia, there is nothing to add to the account in the mono- 

 graph. Dendromyia paracnsis Theobald (Mon. Culic, iii, 316, 

 1903), is apparently a Limatus, as Peryassu says that the pro- 

 thoracic lobes are yellow and the abdominal colors are incised 

 anteriorly on the segments. There is also a Limatus described 

 from Argentina, L. leontinice Brethes (Bol. Inst. Ent. y Pat. 

 Veg., i, 41, 1913) ; but I do not know these species in nature. 



Genus DECAMYIA, new genus 



Type species : Wyeomyia onidus Dyar & Knab. 



Three species fall in this genus, apparently inseparable on 

 colorational characters. The larvae occur in the flower bracts 

 of Heliconia and Calathea. All the species are widely dis- 

 tributed.
