ART. 3. DEOSOPHILID TWO- WINGED FLIES MALLOCH. 11 



there are four such spots, the second and third connected along 

 second vein, the first with a spur of a vein in its center which is 

 emitted from second vein, the dark mark over apex of first vein 

 extending more into the cell; in calliptera there is a large spot 

 on apex of third vein and a narrow brown mark along wing tip 

 between and beyond apices of veins 3 and 4, but in schildi the dark 

 spot is well removed from the apex of third vein and there is no 

 brown marginal mark along tip of wing between the veins; in 

 schildi there is also a fuscous spot in the submarginal cell below 

 the first spot in marginal cell which is not present in calli'ptera. 



Length, 3 mm. 



Type and three paratypes, Higuito, San Mateo, Costa Rica (P. 

 Schild). 



7V^e.— Female, Cat. No. 26685, U.S.N.M. 



SCAPTOMYZA NIGRIPALPIS, new species. 



Female. — Reddish testaceous, thorax slightly, abdomen distinctly 

 shining. Head clay colored, paler on frontal orbits; ocellar region 

 brown ; apices of palpi black or fuscous. Thoracic dorsum with gray 

 pruinescenece and three broad brown vittae, the median one extend- 

 ing to tip of scutellum; pleura with a broad brown vitta along upper 

 margin. Each tergite of abdomen blackish, with an interrupted 

 black facia on anterior half. Legs j^ellow. Wings hyaline. 



Palpi normal, apices with a rather long setulose hair. Humeral 

 angle with one bristle ; only two distinct pairs of dorsocentrals pres- 

 ent; apical pair of scutellar bristles not over half as long as basal 

 pair. Abdomen slender. Legs normal. Inner cross-vein at about 

 one third fron^ base of discal cell; penultimate section of fourth 

 vein about three fourths as long as ultimate section; last section of 

 fifth vein about one third longer than outer cross-vein. 



Length, 1.5 mm. 



Type and three paratypes, Alto Itatiaj'^a Serro do Itatiaya, south- 

 east Brazil, 7,150 feet, February 21, 1922 (E. G. Holt). 



Type.—C2it. No. 26701, U.S.N.M. 



SCAPTOMYZA FUSCINERVIS, new species. 



Female. — Differs from the last species in having the thorax more 

 shining posteriorly on dorsum, the dorsal vittae much less noticeable, 

 the median one not evident on scutellum; the scutellum shorter and 

 convex, not flattened on disk, the abdomen almost uniformly glossy 

 dark brown; and the bases of the wing veins distad of the humeral 

 cross- vein and including the costal vein on almost its entire length 

 darker than the remainder of the veins. 



Length, 1.5 mm. 



Type and two paratypes, same locality as last species. 



7>e.— Cat. No. 26702, U.S.N.M.
