ART. 15 NOTES ON ACALYPTEATE FLIES MALLOCH 25 



MINDANAIA, new genus 



This genus will run down to Stenopterina Macquart in Hendel's 

 key to the genera of this group, possessing a narrowed first posterior 

 cell and one well-developed orbital bristle on each side of frons. A 

 comparison of the genotypes, however, discloses the fact that that of 

 the new genus has many fine erect black hairs on the upper lateral 

 triangular section of the postnotum which are lacking in Stenop- 

 terina. 



Genotype. — Mindanaia latifasciata, new species. 



MINDANAIA LATIFASCIATA. new species 



Female. — ^Head fuscous, frons dark brown, paler anteriorly and 

 narrowly along eye margins, upper orbits shining black ; face glossy 

 blackish brown below, white dusted on upper half; antennae and 

 palpi fuscous, basal segments of former paler. Thorax and abdomen 

 black, with but slight indications of bluish tinge, dorsum of former 

 with grey dust forming faintly indicated vittae anteriorly, the cen- 

 tral one rather broad and the most 

 distinct. Abdomen largely glossy, 

 slightly grey dusted on sides of the 

 basal two segments ; hairs pale. Legs 

 fuscous, yellowish at bases of hind 

 femora, apices of mid tibiae, and on figure 8.— wing op mindanaia 



' •■- " LATIFASCIATA 



basal two segments of mid and hind 



tarsi. Wings hyaline, with fuscous marks as in Figure 8. Halteres 



yellow. 



Frons over twice as long as wide, unpunctured, four verticals well 

 developed, occelars microscopic; antennae extending about four- 

 fifths of the distance to epistome, third segment narrowed apically; 

 arista with the upper hairs about half as long as the width of third 

 antennal segment, the lower hairs shorter; occipital bristle present; 

 face shallowly foveate on sides; labrum higher than width of third 

 antennal segment. Lateral anterior marginal bristles present on dor- 

 sum of thorax, humeral and mesopleural present; scutellum with 

 discal hairs and four marginal bristles. Fourth visible tergite about 

 1.5 as long as third. Legs normal, mid tibia with one apical ventral 

 bristle. Wing venation as Figure 8, first and third veins setulose 

 to apices, fifth vein bare. 



Length, 6.25 mm. 



Type.—Femiile, Cat. No. 43060, U.S.N.M. Zamboanga, Mindanao,

Genus PSEUDEPICAUSTA Hendel 



Pseiidepicausta Hendel, Abhancl. k. k. Zool.-Bot. Gesellsch., Wien, vol. 8, 

 p. 112, 1914. 

 This genus superficially resembles Plagiostenopterina Hendel, but 

 the ultimate section of the fourth wing vein is never curved forward
