WYEOMYIA BROMELIARUM 131 



stalk green, with red and yellow blush/' February 10, 1908 (A. H. Jennings) ; 

 San Pablo, Canal Zone, February 12, 1908, larvae in "banana bromelia " 

 ( = HeUconia) which contained abundant water while the true bromelias were 

 dry (A. H. Jennings). 



This species was identified for Mr. Busck as Wyeomyia galoa, but further 

 study has caused us to separate this as a distinct species. Mr. Busck's locality 

 for the larvae, mentioned above, where they are recorded as occurring in water 

 in the prints of horse's feet, is probably erroneous, and due to some confusion 

 of the labels or mixture of the cultures. Mr. Busck's notes mention only the 

 Uranoiwma calosomata found there, and we think it likely that he would have 

 noticed the sabethine larvas if they had really occurred in such an unexpected 

 location.

Obiginal Description of Wyeomyia asullepta (Dyar & Knab, not Theobald) : 



Described from Guiana. We have the larvae from Mr. Urich in Trinidad. The 

 determination seems plausible and we have not rejected it. 



The following is an abstract of the table : 



1. Anal processes two, the upper pair aborted 2 



2. Tube and plate with heavy black basal ring asullepta 



Original Description of Wyeomyia bromeliarum : 



We propose this term for the larvae described by us as W. asullepta Theob. (Journ. 

 N. Y. ent. soc, xiv, 228, pi. xv, fig. 69, 1906). The single bred adult has, most un- 

 fortunately, been nearly entirely destroyed since it was identified by Mr. Coquillett, 

 and we are unable to check the identification. There is no reason, however, to sup- 

 pose it the same as the continental form, asullepta.

Description of Fej^iale, Male, and Larva of Wyeomyia bromeliarum: 



Female. Proboscis rather short and stout, swollen apically, vestiture black 

 with a bronzy and blue reflection ; labellae small, rounded, with fine outstanding 

 setae. Palpi short, flattened, one-fifth as long as proboscis, bronzy black. 

 Antennae moderate, the joints slender, subequal, rugose, coarsely pilose, black ; 

 tori subspherical, with a cup-shaped apical excavation, dark brown, with 

 silvery- white pruinosity ; hairs of the whorls long, rather sparse, black. Clypeus 

 rounded, convex, dark brown, silvery pruinose. Eyes separated at the vertex 

 by a narrow wedge, bluish black. Occiput clothed with flat dark-brown scales 

 with a metallic reflection, a white spot at the vertex, a white patch below, the 

 two Joined by a white border along the eyes ; two long seta3 at the vertex and 

 small ones along margin of eyes. 



Prothoracic lobes elliptical, well separated, clothed with flat scales, blackish 

 with bronzy and blue reflection, a patch of silver scales at base ; a row of setae 

 along anterior margin. Mesonotum clothed with elliptical, flat dark-browTi 

 scales with a bronzy and blue reflection ; scales on anterior margin white, below 

 lateral angles gray; setae over roots of the wings brown. Scutellum trilobate, 

 with the vestiture similar to and continuous with that of mesonotum, each lobe 

 with a small tuft of brown bristles. Postnotum elliptical, prominent, a broad, 

 low median carina, dark brown, a group of small setce near the posterior margin. 

 Pleurae luteous with a dark-brown patch, coxae luteous, clothed with elliptical, 

 flat, silvery-white scales. 



Abdomen subcylindrical, compressed, truncate apically, and with many long 

 dark-brown terminal setae; dorsal vestiture black, with a slight metallic reflec- 

 tion; venter yellowish white, the colors separated at the sides in a straight 

 line; scales along mid- ventral line slightly raised.
