166 THE EARLY STAGES OF TABANID^ 



"Lateral prothoracic striated areas are not more than half as long as the dorsal, 

 striation not finer than that of the middle and lower lateral areas of the mesothorax, 

 striated portion shining; a small smooth spot adjoining the impressed line below; 

 remaining upper lateral thoracic areas a little less coarsely striated, but not 

 strongly different from that of the prothorax; abdominal lateral areas a little more 

 finely striate; dorsal and ventral areas with margins striated, disks nearly smooth 

 in adult larvae, last segment more strongly striate, especially beneath.'' 



"Dark annuli distinct, broad, including false feet, a dislinct transverse dorsal 

 and ventral pale spot in front of the false feet; abdominal annuli often with a 

 small triangular backward prolongation on median line above. Prothoracic 

 lateral space occupied by a pale brownish fuscous quadrate spot in front of the 

 striated space. Meso- and metathoracic lateral stripes usually distinct, but 

 slender, scarcely dilated posteriorly, lateral edges of dorsal areas diverging; lateral 

 stripes of abdomen almost wanting, except on last two or three segments. In 

 these stripes the punctures of the upper and lower rows are indicated by rounded 

 pale dots, and those of the inner rows by elongate dots. Last segment with bases 

 of respiratory tube and anal prominence encircled with dark rings; joined by a 

 lateral connection, its dorsum with at most a short basal line or pair of dots on 

 each side. Coarser pubescence of false feet tipped with pale brownish." 



"Main internal tracheae thick and noticeable, especially in young larvae, 

 lustrous, subparallel, not strongly sinuate, nearly straight posteriorly; terminal 

 stigmatal spine dark reddish brown, smooth, usually protruded."' 



The pupa (Plate 11, Fig. 125; Plate 13, Figs. 153 and 161) has 

 been described by Hart as well as by Hine, both of whom reared the 

 adult from pupas obtained from adult larvae taken in nature. The 

 following is Hart's description. 



" Pupa, female. — Length about 30 mm., diameter about 6 mm. Light brownish 

 fuscous, thorax paler, shining, abdomen roughly transversely WTinkled, and sub- 

 opaque. Palpal sheaths distinct, as far apart as are the setae borne by the 

 larger tubercles at the center of the anterior surface of the head [Plate 13, Fig. 

 153]; surface between them rounded, bearing a small wrinkled tubercle at middle; 

 antennae and tubercles darker than surrounding surface; ocellar tubercles dis- 

 tinct; prothoracic spiracular tubercles slightly but evenly elevated in a plane 

 parallel to that of the surrounding surface; rima nearly straight in its outer half, 

 inwardly curving strongly forward, and ending in a conspicuous hook; free mar- 

 gin of tubercle rounded at tip." 



"First abdominal with two distinct setae each side above the spiracles; ab- 

 dominal spiracular tubercles rounded, broad behind, low-subhemispherical, rima 

 long, following posterior border of tubercle, sHghtly curved at middle, more 

 strongly curved forwards at each end; on anterior surface a transverse groove 

 extending across the tubercle, but not as long as the rima. Fringes of unequal
