twice as high as wide at base and carrying six setae; exterior pre- 

 scutal sclerite distinct, somewhat smaller than the interior, with a 

 tubercle carrying three setae. Interior scuto-sciitellar sclerite dis- 

 tinct carrying five setae on its tubercle ; exterior scuto-scutellar scle- 

 rite distinct, tubercle with about six setae. Alar sclerite large, with 

 about 10 setae. Spiracular area with a sclerite surrounding tlio spir- 

 acle; about four small setae present. Epipleural area triangular with 

 an oval sclerite carrying five or six setae. Prehypopleural sclerite 

 flat, heavily chitinized, with one or two small, pointed setae; post- 

 hypopleural sclerite somewhat protuberant, carrying about three 

 small setae. Eusternal sclerite large, oval, convex, with about 10 

 setae on each side. Each sternellar sclerite distinct but small, carry- 

 ing one seta. 



First to seventh ahdoininal segments (fig. 10). — Interior prescutal 

 sclerites distinct, not fused in the sagittal line, number of setae on 

 each sclerite about six; exterior prescutal sclerite of moderate size 

 and separated from the interior sclerite by a distance equal to about 

 three times its own diameter, tubercle carr^dng about three setae. 

 Interior scuto-scutellar sclerite distinct, with about five setae; ex- 

 terior scuto-scutellar sclerite closer to the sagittal line than the 

 exterior prescutal, about four setae present. Parascutal area without 

 anterior sclerite; posterior sclerite large, carrying 8 to 10 setae; 

 spiracle not located in a distinct sclerite. Epipleural sclerite large, 

 protuberant, and having seven or eight setae. Hypopleural sclerite 

 with about five setae. Eusternum with a large sclerite, carrying four 

 or five setae on each side. Parasternal lobe ( = coxal lobe, Hopkins) 

 present, having a round sclerite with four setae. Sternellar sclerite 

 paired, small, distinct, with one seta. 



Eighth abdominal segment (fig. 13). — Interior prescutal sclerite 

 distinct, not fused medianly with that of the opposite side, number 

 of setae four or five; exterior prescutal sclerite with three setae. 

 Interior and exterior scuto-scutellar sclerites fused into a single, 

 medial sclerite, carrying six setae on each side. Posterior parascutal 

 sclerite distinct, with about eight setae. Segment otherwise similar to 

 the preceding segments. 



Ninth abdominal segment (fig. 13). — Pygidial shield comparatively 

 small, half as wide and somewhat shorter than the eighth abdominal 

 segment, approximately semicircular in dorsal outline; anteriorly and 

 along the free margin swollen and with the anterior and marginal 

 posterior parts of the shield separated b}^ a transverse, crescent- 

 shaped depression. Setae numerous, arranged in a single anterior 

 row with two setae on each side, and an iri*egular double row in the 

 free margin with from 8 to 10 setae on each side; setae generally 

 almost as long as the sagittal length of the shield. Ventral part of
