defined. The ground-color appears brownish yellow, but I suspect that in fresh 

 and mature specimens there may be some dark marks. 



Wings a little pointed, yellowish hyaline; a dark brown spot at base from the 

 costa to fourth vein, covering the extreme apex of costal cell, base of marginal and 

 submarginal cells, and the middle of first basal cell; an oval spot of same color along 

 apex of second vein, covering the entire apex of marginal cell and extending into 

 the middle of submarginal cell; the anterior cross-vein narrowly, the posterior one 

 quite broadly, bordered with dark brown; apical portion of third vein distinctly 

 infuscated and the infuscation extending over the apex of the submarginal cell, 

 though diluted. Third vein ends exactly at the apex of the slightly pointed wing; 

 second vein rather strongly curved at apex; the distance between the tips of second 

 and third veins about twice the distance between the tips of third and fourth veins! 

 first posterior cell hardly wider at middle than at apex; the distance between ante- 

 rior and posterior cross- veins hardly one-fourth longer than the first section of third 

 vein; the posterior cross- vein about the length of the ultimate section of fifth vein; 

 anal vein quite strong, reaching slightly over halfway towards posterior margin; 

 fourth vein thinned in its apical portion; costa fuscous, veins otherwise yellowish, 

 but blackish where the brown marks are situated; the vein closing the anal cell also 

 blackish. 



The fronto-orbital, vertical, and ocellar bristles of almost equal size; the upper 

 reclinate fronto-orbital appears to be only midway between the inner vertical and 

 the lower reclinate and only slightly higher up than the lower ocellus; the uppermost 

 setula of the occipito-orbital fringe is lengthened and diverging from the other 

 setulae of that fringe; postverticals minute, strongly convergent, touching at tips; 

 on lower occipital orbit a small bristle-like setula, distinctly differentiated from the 

 small setulse of the occipito-orbital fringe; between the two diverging sternopleural 

 bristles a minute setula; the anterior dorso-central bristle a little weaker than the 

 posterior one and of almost equal size with the prescutellar pair, which are situated 

 almost on a level with the posterior dorso-central; the presutural bristle shorter 

 than the notopleurals, but almost as strong; the anterior supra-alar weak; the 

 posterior postalar minute; the two apical scutellar bristles are decussate in the 

 specimen. The bristles appear in certain lights more or less yellow, expecially the 

 lower fronto-orbitals, humeral, noto- and sterno-pleurals. Along the exterior side 

 of middle coxae a row of yellowish, bristly hairs, the uppermost the strongest. 



Habitat: Brazil, Espirito Santo, Munez Freire, June 17, 1908, Col- 

 lected by J. D. Haseman, Carn. Mus. Ace. 3579. Type in Carnegie 

 Museum, Pittsburgh. The species is dedicated to my friend, the 

 intrepid explorer. Dr. J. D. Haseman. 



There is an extreme resemblance between this species and L. macu- 

 losa Coquillett^"* and I was strongly inclined to refer it to the latter 

 species, which I had before me from Kansas, Illinois, and Pennsyl- 

 vania, but considering the differences between the unique Brazilian 

 specimen and maculosa, although they appear slight, I have preferred
