Stripes on the mesonotum, and shape of the three maculae. 

 In one male specimen from Mexico the entire abdomen is 

 dark fuscous, but this is perhaps due to greasing. Cameron 

 seems to intimate that what I call thoracicus is really flavo- 

 scutellatus Br., but this is impossible, for Brull6's species 

 has only one macula in the wing while thoracicus has three, 

 or at least (sometimes) two. E. trispilus Szep. is appar- 

 ently a synonym of this species, and Ophion trimaculatus 

 Tasch.* certainly is. 



Distribution. — This species is apparently tropical but with 

 a wide range which may extend beyond the tropics. It has 

 been reported from Cordova, San Rafael (Jicoltepec) Mexico; 

 Cuba ; Bog Walk, Parish of St. Catherine, Jamaica ; Merida, 

 Venezuela ; Mapiri, Bolivia ; Nova Friburgo, Brazil ; and I 

 have seen specimens from Mexico ; Cuba ; Balaclava, Jamai- 

 ca ; San Francisco Mountains, Santo Domingo, and Chau- 

 chamayo, Peru. 



Life history. — Nothing is recorded concerning the life his- 

 tory of this species and no hosts have been reported. One 

 specimen from Santo Domingo was taken in September. 

 The single cocoon which I have seen is dark brown with two 

 irregular, longitudinal black stripes : 20 mm. long and 8.5 

 mm. broad. 



Location of specimens, — American Entomological Society, 

 two 9 cotypes, No. 77. U. S. National Museum, homotypes 

 and specimens from San Rafael, Mexico ; Cuba ; Jamaica ; 

 San Francisco Mountains, Santo Domingo ; Grenada. Massa- 

 chusetts Agricultural College, homotype, cf , Mexico. Hun- 

 garian National Museum. Three cf cotypes of E. trispilus 

 from Mexico, Venezuela, and Bolivia. 



* The name Ophion trimaculatus Taschenberg, 1875, was a homo- 

 nym, having already been used by Olivier, Encycl. Meth., Ins., VIII, p. 

 59, 1811, sixty-four years before. Szepligeti transfers the species to the 

 Genus Enicospilus , but with no change of name and even if the spe- 

 cies were good the name is not valid. According to rulings of the 

 Committee of Nomenclature, "A stillborn homonym can not be used 

 again even when a species is transferred to another genus."
