94 DIPTERA OF NORTH AMERICA. 



Note. Judging by the character of the picture and the vena- 

 tion of the wings, this species seems to have some relation to T. 

 solidayinis Fjtch. [I possess specimens from Maryland which 

 answer this description, except that the abdomen is brown, and 

 that there is an elongated hyaline spot at the tip of the sixth 

 longitudinal vein. Macquart (Dipt. Exot. II, 3, p. 229) had 

 evidently a similar specimen before him, and took it for Trypeta 

 comma. I incline to believe that he was right. 0. S.]

 29.) 



Pale reddish-yellow ; wings brownish-yellow, marked with limpid drops 

 and a black dot towards the tip, the borders being limpid and radiated 

 with brownish-yello^f. Long. corp. 0.3. 



Antennae brownish-yellow, with the third joint very short. Face 

 yellowish, very polished, with three black dots. Front ochreous, 

 on each side with a deep black dot near the antennas. Eyes golden- 

 green, speckled with purplish. Thorax almost brownish-yellow, 

 with indistinct darker stripes. Scutellum polished, with two black 

 dots at the tip. Abdomen ochreous, with bristly hairs and indis- 

 tinct fuscous spots. Wings shining, clay colored on the disk, from 

 which several clay-colored rays, margined with brown, run to the 

 borders of the wing; on the disk there are several limpid drops 

 encircled with black, and some brown spots appearing violet in a 

 certain light, and farther towards the apex there is an impressed 

 black dot ; on the posterior border, towards the base, some limpid 

 drops may be seen. The costa has two or three small bristles at 

 the end of the auxiliary vein.

APPENDIX II. 



In order to complete this paper on N. A. Trypetidx, it has been deemed 

 useful to reproduce the descriptions of the species of this family found in 

 former authors, but as yet not identified by Mr. Loew. As four of the 

 descriptions of this category are already presented by Mr. Loew in the 

 first appendix, I give here the remaining, according to the list of species 

 on p. 61. Four species only from Jamaica, described by Mr. Walker, have 

 been omitted a as their descriptions, published in English, will always be 

 easily accessible to those desirous to extend their collections to the West
