Brachycyrtus baltazarae, new species 



Figure 1,6 



This new species can be immediately recognized by its large size. 

 The only knowTi specimen, a female, is approximately 9 mm. in 

 length. All other known species in the genus measure 6 mm. or less. 

 The new species is further distinguished by the lack of costulae on 

 the propodeum. 



Head yellow; ocellar triangle black, joining black spot extending 

 dorsally and laterally to occipital carina but with lateral limits 

 visible dorsally; scape and pedicel yellow below, blackish above; 

 flagellum testaceous below, darker above (apical segments missing 

 from both antennae). Thorax yellow, rectangular median black 

 spot on scutum, flanked on each side by elongate triangular black 

 spot, scutellar fovea and adjoining area of scutum black, elongate 

 black spot on pleuron near mesopleural suture, anterior black spot on 

 lateral basal areas of propodeum. Legs yellow except apices of femora 

 and tibiae, apical tarsal segments, and bases of hind trochanters and 

 tibiae, all of which are more or less bro\vnish or blackish; v/ings 

 hyaline, venation dark brown. Abdomen yellov,'^, petiole blackish 

 at extreme base (difficult to see) with a laterally elongate blackish 

 band before the sphacles, blackish band at base of segments 2-6, 

 segment 7 mostly brownish or blackish except narrow band at apex; 

 ovipositor sheaths blackish. 



Head lighth'' but closely punctate, first flagellar segment of antenna 

 3)2 times as long as vdde. Thorax strongly but rather closely punctate 

 except propodeum, which is mostly granular with scattered punctures 

 basally; epomiae flangelike and joining dorsall}" scutellar fovea 

 carinate anteriorly and crossed by several carinae ; punctate scutellum 

 with lateral carinae fla,ngelike at fovea; postscutellum small and 

 shining; propodeum lacking costulae, areola and petiolar area fused; 

 propodeal spiracles slitlike and proportionatcl}^ larger than in other 

 IvQOwn species of the genus. Forewing with ncrvulus postf ureal by 

 about one-third its length; cubitus, between hitercubitus and second 

 recurrent, fully 3)2 times as long as intercubitus. Petiole widest at 

 spiracles then narrovring so that its apical width is about three- 

 fomlhs that at spiracles. Ovipositor sheaths only very slightly 

 longer than petiole. 



Described from the unique female collected by F. R. Candelaria, 

 Sept. 17, 1953, on Mount Maquiling, Philippine Islands, and named 

 in honor of Miss Clare Baltazar, entomologist with the Bureau of
