PSOROPHORA HOWARDH 545 



This fine species is respectfully dedicated to Dr. L. O. Howard, whose investiga- 

 tions have so much increased our knowledge of the early stages and distribution of 

 the members of this important family. 



Desceiption of Female, Male, Laeva, and Egg of Psorophoea howaedii: 



Female. Proboscis slender, uniform, labellse small, tapered; clothed with 

 small blue-black scales and numerous small black curved setae. Palpi half as 

 long as proboscis, clothed with small blue-black scales, densely setose, some of 

 the basal ones long. Antennse slender ; joints subequal, second joint somewhat 

 longer, all pilose ; tori subspherical, pale brown, a few small setae within ; hairs 

 of whorls sparse, not long. Clypeus elongate, prominent, shortly rounded, 

 lateral basal angles prominent, nude, brown, blackish centrally. Eyes black. 

 Occiput broad and exposed, sordid blackish, vestiture of rather dense, broad, 

 curved white scales and numerous short brownish setae ; a rather broad bare stripe 

 along median suture. 



Prothoracic lobes moderate, well separated, ocher yellow, with many short 

 brownish setae which form a dense cluster at apex. Mesonotum convex, promi- 

 nent in front, brown and black, shining; a median longitudinal line of small 

 blackish scales mixed with brownish-tipped bristles extending to ante-scutellar 

 space ; on each side of it a broad bare stripe ; bordering this outwardly another 

 row of scales and hairs similar to median one, interrupted anteriorly and extend- 

 ing close to base of mesonotum ; anterior angles broadly nude except for a few 

 small bristles; above this nude area is a broad patch of broad white scales, 

 pointed anteriorly and extending obliquely backward to root of wing; white 

 scales about ante-scutellar space and across its middle ; a broad bare stripe on 

 each side of ante-scutellar space. Scutellum trilobate, with a few white scales, 

 more especially on mid lobe, each lobe bearing many black bristles. Postnotum 

 elliptical, nude, dark brown. Pleurae brown and shining black, rather densely 

 clothed with elliptical white scales ; coxae yellowish, with many dark bristles, a 

 patch of small bluish scales on anterior pair. 



Abdomen subcylindrical, flattened, posterior segments tapered; dorsally 

 clothed with dark scales which have a bright violet-blue luster without any green 

 tint, except on last two segments, which are greenish and coppery iridescent ; 

 laterally a number of flat white scales which tend to form lateral lines and basal 

 and apical segmental patches; first segment dorsally white scaled, with many 

 pale hairs; venter largely white scaled, a series of medio-basal bright-blue spots, 

 sixth segment largely blue-black scaled, seventh segment with iridescent scales ; 

 setae dense, short, most numerous along the sides and posterior edges of seg- 

 ments. 



Wings rather narrow, entirely smoky, somewhat darker on costal region ; veins 

 dark; stem of second marginal cell considerably shorter than its cell, that of 

 second posterior cell about equal to its cell ; basal cross-vein much less than its 

 own length distant from anterior cross-vein ; scales black with a bright blue re- 

 flection, outstanding scales towards apex of wing long and rather broadly lanceo- 

 late. Halteres with pale stems and blackish knobs. 



Legs long, rather slender ; integument of femora and tibiae yellowish ; femora 

 clothed with small, appressed yellow shining scales, a broad apical ring of dense, 

 black, strongly outstanding scales; tibios clothed with semi-erect smoky scales 

 with metallic blue reflections, a broad apical ring of dense, outstanding black 

 scales with blue and iridescent reflections, a line of pale iridescent scales to near 

 apices; tarsi of all the legs with very slightly raised blackish vestiture and 

 silvery-white rings at bases of first and second joints. Claw formula, 

 1.1-1.1-1.1. 



Length : Body about 9 mm. ; wing 6 mm. 



Male. Proboscis straight, rather short, uniform, blackish scaled. Palpi 

 exceeding the proboscis by almost the length of the last two joints, which are
