the second basal and anal cells and the bases of the third and 

 fourth posterior cells ; the third band involves the furcation 

 of the second vein, the posterior cross-vein, and sends a 

 branch to the apex of the first posterior cell ; several small 

 detached spots occur outwardly on the veins, but there is no 

 spot at the apex of the upper branch of the third vein. Length : 

 Body, about 20 mm. ; wing, 24 mm. 



St. Elizabeth, Santa Cruz Mountains,, Jamaica, altitude 

 1,500 feet, 1 specimen, October 14, 1899 (C. B. Taylor). 



Type, Cat. No. 19355, U. S. Nat. Mus. 



Nearest to Hyperalonia cerherus Fabricius, but differs by 

 its much larger size, the more restricted black fasciae of the 

 wings, black tibise, absence of white markings from the pos- 

 terior portion of the abdomen and other details. The long 

 red pubescence present at the sides of the venter in this species 

 is absent in cerherus. In the wing of gargantiia the clear 

 spaces between the black fasciae reach forward to the first 

 vein, while in cerherus the black fasciae are more or less con- 

 fluent in the anterior region. 



Heterostylum haemorrhoicum (Loew). 



Bombylius hcemorrhoicus Loew, Berl. Ent. Zeitschr., vol. 7, p. 



300 (Centur. iv, species 46). 1863. 

 Bombylius semirufus Loew, Berl. Ent. Zeitschr., vol. 16, p. 78 



(Centur. x, species 41), 1872. 



A specimen in the U. S. National Museum collection bears 

 the label "Grand Anse, Hayti, P. R. Uhler," and is evidently 

 one of the original series from which the type of Bombylius 

 semirufus was derived. The specimen is a typical Heterostyl- 

 um in every respect; Loew compares the species with Bom- 

 bylius hcemorrhoicus, which he had previously described from 

 Cuba, and which therefore also belongs here. This view is 

 supported by Loew's comparison of hcemorrhoicus with Bom- 

 bylius ferrugineus Fabricius, which belongs to Heterostylum. 

 In the descriptions of hcemorrhoicus and semirufus no tangible 

 differences are apparent and both descriptions apply equally 

 well to the specimen before me. While in the absence of 

 Cuban material the synonymy cannot be made positive, it is 

 at least highly probable and was already suspected by Loew 

 himself. Date of publication. May, 15, 1915.
