5. Head velvet black. Its tomentum silvery-white, the pile black; antennae, pro- 

 boscis and palpi black, their tomentum mixed brown and silvery-white, that on

 anterior half with two silvery-white subdorsal vittae, and with a silvery white 

 arcuate lateral line extending the entire length of the thorax; pleura marked with 

 several spots of silvery-white tomentum; scutellum with two spots of similar 

 tomentum on the upper side and one at the tip. Abdomen black, its tomentum 

 violaceous, that at base of each segment white. Legs brown, femora largely yellow- 

 ish, the tomentum mixed brown and silvery-white, that at apices of tibiae pure white, 

 each end of tarsal joints white, most extended on the hind tarsi; tarsal claws desti-

DeSCEIPTION op FEMiLLE, MALE, LaEVA, PUPA, AND EgQ OF OeTHOPODOMYIA SIGNIFER : 



Female. — Proboscis straight, rather long, slightly enlarged at tip, clothed 

 with bronzy-black suberect scales with many milky white ones dorsally tend- 

 ing to form longitudinal striae. Palpi elongate, more than one-third the 

 length of the proboscis, slender, very slightly enlarged at apex; terminal seg- 

 ments with scattered long setae; vestiture of deep brown scales with a heavy 

 sprinkling of white ones, apices silver scaled. Antennae filiform, rather long, 

 the joints snbequal, coarsely ciliate, second to fifth with a row of white scales 

 along inner side; hairs of whorls sparse, moderate, brown; tori rather small, 

 dark brown, with an oblique ridge of erect white scales. Clypens short, convex, 

 broad at base, conical, blackish-brown, nude. Eyes separated by a narrow 

 ridge of white scales. Occiput blackish-brown with recumbent, narrow curved 

 white scales and with numerous long, very slender, erect, forked deep brown 

 ones ; ocular margins and cheeks silvery-white scales ; bristles along margins of 

 eyes long and coarse, black, some longer black ones projecting between the eyes. 



Prothoracic lobes small, well separated, prominent, contiguous with head ; an 

 oblique row of white scales crosses them and they bear a number of very coarse 

 and long black bristles. Mesonotum very deep brown, thinly clothed with 

 minute, narrow, curved, bright reddish-brown scales and with six very narrow 

 longitudinal lines of larger and broader white scales; two of these lines are 

 subdorsal and extend over anterior three-fourths of mesonotum; two are sub- 

 marginal and extend the entire length of mesonotum; midway between the 

 subdorsal and the submarginal stripes are short stripes extending from the 

 middle to a point opposite the anterior angles of the antescutellar space, at 

 which point they are slightly interrupted, and converging posteriorly, continued 

 by longer suberect white scales, continuing over tiie scutellum where some 

 very long white scales stand out behind more than the entire length of the 

 scutellum; hairs abundant, coarse and very long, black. Scutellum large, 

 median lobe prominent and broadly rounded; besides the two lines of white 

 scales above mentioned there are patches of white scales at the outer angles; 

 three groups of coarse long brown sette. Postnotum prominent, elongate, with 

 a small median longitudinal ridge, brown, slightly pruinose, nude. Pleurae and 

 coxae deep brown and luteous, clothed in part with broad white scales. 



Abdomen subcylindrical, slightly enlarged at middle, apex blunt; cerci 

 slender, protruding; dorsal vestiture dull black, with basal triangular patches
