ABT.5 GENERIC REVISION OF THE FOSSORIAL WASPS— PARKER 31 



This species seems close to Sttctia mexicama Handlirsch and. like 

 that species, has the hind metatarsus unusually long, in this species 

 nearly as long as the hind tibia. The apical segment on the anterior 

 and middle tarsi (posterior missing) is marked with a black spot. 

 The sixth segment of the flagellum is excavated on its posterior sur- 

 face and is slightly spinose as is also the seventh and ninth. The 

 tenth, eleventh, and twelfth segments are also excavated below. The 

 lateral spines of the seventh tergite are almost squarely truncate. 

 The wings are hyaline. The punctation of the scutellum is relatively 

 fine and uniform; that of the scutum is similar to that of the scut«llum 

 save that very fine punctures are scattered among the coarser ones. 



Length about 25 mm. Described from a single male (the type) 

 taken by J. Chester Bradlej' and bearing the label, " La Sombra to 

 El Encapto, Putumayo Dist., Peru, Aug. 23, '20."" 



Type. — In the collection of Cornell LTniversity. 



STICTIA MACULATA (Fabricios)

This species is characterized by having broad longitudinal discal 

 stripes on the scutum; fasciae on scutellum, metanotum and pro- 

 podeum; the sides of the thorax and propodeum wholly yellow or 

 nearly so, and on some specimens the greater part of the venter of 

 the mesothorax also yellow ; the discal spots on tergit^s 1-4 separated 

 from the lateral spots; and the tarsi preponderantly or entirely 

 yellow. On some specimens the maculations on the first tergite 

 resemble those found on Stict'ia signata but in all cases observed the 

 U-shaped marks were more or less broken. On some specimens one 

 or both of the discal spots on the second t«rgite may be united with 

 the corresponding lateral spot, but on no specimen studied did I find 

 such a union on the fourth tergite — here the discal spots are always 

 distinct. The sixth tergite of the female is invariable black and 

 the form of the lateral spines of the seventh tergite of the male is 

 similar to that of signata.
