weak, but extend far beyond the anterior cross-vein. On one wing in the single speci- 

 men before me, there are two short spurious veins extending from the costa into the 

 marginal cell, on the other wing only one of these veins is present. We cannot con- 

 sider them as being of any taxonomic importance. Length, 9 5 ^nm. One female.

 Eutreta aurantiaca, sp. nov. (PI. Ill, Fig. lo). 



9 . Black ; the broad, flattened front yellowish brown with black bristles, those 

 nearest the vertex having small black dots at their bases ; face more whitish, broad, 

 flattened, slightly receding ; oral opening large ; margin not produced ; antennae yel- 

 low ; third joint slightly concave above, anterior corner sharp ; arista yellow at base, 

 brownish toward tip ; occiput black. Thorax black with reddish pollen and thick 

 reddish pile ; scutellum shining black with a small yellowish spot on each side poste- 

 riorly ; the four black bristles as well as those of the thorax and vertex tipped with 

 yellow or white ; metanotum shining black ; legs reddish yellow ; femora with a black 

 spot a little beyond the middle on the ventral side. Abdomen shining black ; each 

 segment, except the first, with three yellow spots ; pile for the most part black, but 

 along the posterior margin of the second segment and in the region of the yellow spots 

 it is golden yellow ; ovipositor shining black, flattened, very short, about as long as 

 the preceding segment. Wings rather broad, rounded at apex, dark brown with 

 whitish hyaline spots somewhat equally distributed over the whole surface of the 

 wing, being largest along the anterior and posterior margins, those in the basal por- 

 tions are somewhat infuscated, usually with a yellowish tinge ; first and third veins 

 with bristles. Length, 24 mm. One female.

 Carphotricha culta Wied. 



I have before me a number of specimens all of which I believe be- 

 long to this species, but which may be easily separated into three 

 groups ; the first of these contains forms which are undoubtedly T. 

 ciilta Wied., differing in no respect from Loew's figure and descrip- 

 tion. The second group contains smaller, lighter-colored fornns which 

 I would unhesitatingly identify as T. cultaris Coq., were it not for the 

 fact that I find intermediate forms. The typical members of this 

 group have only one brown ray between the apices of second and 

 third veins, others have only a slight trace of a second ray, still others 

 have a complete second ray ; the length of the last segment of the ab- 

 domen varies, so this character is useless ; the only constant difference 

 I can find is the absence of the darkish spots in the second posterior 

 cell, but in the first group containing typical culta I find some speci- 

 mens in which this spot is nearly or quite wanting. The third group 

 contains specimens slightly larger and darker than typical culta but 

 with three brown rays between apices of second and third vein and a
