 Homotypes — Accession No. 45089, Illinois State Laboratory of 

 Natural History, Urbana, 1 male, 1 female on a single slide (Tuna- 

 punta, Trinidad). For types of the synonymic occidentalis, see 

 before. 



Some years after its original description the author ^ of this species 

 amended his former description as follows : Head and abdomen blue- 

 black; thorax, except the pronotum, bright yellow; wings hyaline, 

 with a dusky band beneath the marginal vein.' 



As has been intimated, the species was redescribed as new to 

 science by Howard (1894), under the name occidentalis. The original 

 description of occidentalis agrees closely with the type specimen of 

 flavopalliata Ashmead and because of the fact that the structural 

 characters of the types of both are identical and that the difference 

 in coloration between them is small, other specimens gradating 

 between, it is quite evident that there is some color variation and 

 that occidentalis represents the variation bearing a minimum amount 

 of yellow on the thorax; also the brown of the body evidently varies, 

 being very deep in some specimens, nearly, if not, black; usually, 

 however, brown predominates. But it must be remembered that I 

 have not seen specimens in nature. The fumated area of the fore 

 wing may also vary, sometimes breaking into spots disto-cephalad. 



I append the original description of occidentalis for completeness 

 and convenience.^ 



SIGNIPHORA OCCIDENTALIS, n. sp. 



Female. — Length, 0.53 mm. ; expanse, 1.2 mm. ; greatest width of fore wing, 0.09 mm. 

 Antennal scape robust, reaching to middle of eyes; pedicel large, stout, rather more 

 than one-third as long as scape; funicle joints 1, 2, and 3 subequal in diameter, very 

 small, together only a little over one-third length of pedicel and considerably less 

 than the tip width of the pedicel; increasing in length from 1 to 3; club nearly as long 

 as scape and pedicel together, long oval when seen from side, twice as wide as pedicel, 

 narrow with parallel sides when seen from above, scarcely wider than funicle joint 3.
