hairs. Wings (fig. 7) with venation very similar to pocciloptcra but the 

 costa extends to distinctly beyond end of third vein while in that species it 

 does not, the cross veins are not so closely approximated and the penultimate 

 section of fourth vein is not so much deflected as to appear like a portion 

 of the outer cross vein. Fore femora with rather long bristles on apical 

 half of ventral surface; the other bristling of legs as in previous species. 

 Basal joint of hind tarsus swollen, second joint elongated, but not so 

 distinctly swollen as basal. Length, 1 mm. 



Holotype.— cf , Juan Vinas, May 3, 1910, near brook, forest 

 edge, 2500 feet altitude. Type No. 6021. 



Paratype. — Juan Vifias, 2500 feet, near Rio Reventazon, June 

 28, 1909. 

 Leptocera (Limosina) meridionalis new species (Fig. 11.) 



Male. — Yellow, ocellar region brownish. Mesonotum browned posteri- 

 orly and on lateral margins; scutellum browned; pleura with a black-brown 

 mark longitudinally on middle from anterior to margin and the lower half 

 blackened. Abdomen shining black-brown, last segment with inconspicu- 

 ous pale posterior margin. Legs yellow, bases of all femora darkened. 

 Wings with large brow^nish spots arranged as shown in figure 11. In cases 

 where these markings are distinct they will present the appearance of three 

 fasciae. Veins brown. Halteres clear yellow. 



Frons half the width of head, outline less distinctly emarginate than in 

 vittata; 2 orbital bristles present, as in vittata, the central setulae (2-3) 

 present but very weak; antennae divergent, but not. lying close to the eyes, 

 of good size, the third joint slightly larger than second, pilose; arista genic- 

 ulated, distinctly pubescent, its length about equal to 2 times the width of 

 the frons; face concave in profile, the mouth margin produced; lower margin 

 of eye with a rounded emargination; cheek as high as third joint of antennae, 

 vibrissae distinct, the other hairs weak. Mesonotum with the prescutellar 

 pair of dorso-centrals large and distinct, the pair just before level of wing 

 base short and difficult to detect from the short discal setulae; no distinct 

 pleural bristles on type; scutellum large, equal in length to rather more than 

 half the length of mesonotum, disk bare, margin with 4 bristles, the apical 

 pair longest. Abdomen with short surface hairs; hypopygium very large 

 and knob-like, curved under abdomen. Legs slender; surfaces covered 

 with short hairs; fore femora with distinct ventral bristles; mid tibial dor- 

 sal bristles weak; hind tarsus with basal joint swollen, less than one-half 

 as long as the slightly swollen second joint and wuth it equalling the length 

 of the other 3 joints. Wings with venation as in figure 11. Costa not 

 extending beyond end of third vein; inner cross vein situated before end 

 of second vein and about equal in length with outer; veins 4. 5 not traceable 

 beyond the outer cross vein. Length, 1 mm. 



Holotype.—A\'di]\\d2i, 3100 feet altitude, swept, September 15, 

 1909. Type No. 6022.
