REPORT OF THE STATE ENTOMOLOGIST I904 489 



^ Female. Lobes composed of two segments, basal minute, 

 terminal broadl}' dilated, obliquely truncate. Tergum broadly 

 rounded, ventral plate rounding posteriorly to a median incision. 



Taeniorhynchus brevicellulus Theo. Genitalia, male. Basal 

 clasp segment very stout, broadly rounded to a blunt apex. Term- 

 inal clasp segment enlarged at the base and extremity, strongly 

 curved and bearing a short, stout apical spine. Claspette a con- 

 spicuous basal lobe bearing a stout, chitinous spine. Harpagones 

 very stout, enlarged posteriorly and unique because of the two or 

 three stout, recurved, chitinous processes, giving the organ an 

 appearance not unlike that of a bird's beak. Unci approximate, 

 broadly rounded exteriorly, tapering gradually to blunt, approxi- 

 mate apexes, each crowned ventrally with a series of fine, stout, 

 chitinous teeth. Setaceous lobes approximate, well developed, 

 each with four or five stout apical spines. [PI. i6, fig. i] 



Taeniorhynchus aurites Theo. Genitalia, male. Basal clasp 

 segment stout, tapering gradually to a broadly rounded apex. 

 Terminal clasp segment stout, strongly bent at the basal third, 

 also at the apical fourth and with a stout, short, terminal spine. 

 This segment is remarkable because of the very large spatulate 

 appendage near its middle with a conspicuous group of compound 

 branching hairs arising from near its base. The spatulate append- 

 age and the extremity of the segments is also rather thickly clothed 

 with stout, somewhat curved hairs. Claspette a conspicuous basal 

 lobe bearing a very thick, stout, terminal spine with a much smaller 

 one beside it. Harpagones stout, strongly curved at the apical 

 fourth and bearing several large teeth along its roimded extremity 

 and termmated by a pair of very stout, chitinous, recurved teeth. 

 Unci somewhat curved, nearly approximate, expanded at the apical 

 fourth and thence gently rounded to acute, recurved, approximate 

 points. Ventral surface with the apical portion armed with a 

 series of irregular, stout teeth. Setaceous lobes with the eighth 

 segment produced and marked only by a series of stout, transverse 

 spines along the posterior margin of the segment. [PI. i6, fig. 2]. 



Stegomyia fasciata Fabr. Genitalia, male. Basal clasp seg- 

 ment very broad, subtriangular, broadly rounded internally, 

 gently so externally. Terminal clasp segment rather stout, slightly 

 swollen at distal third, tip abruptly narrowed and bearing a rather 

 stout terminal spine. Claspette a conspicuous internal subapical 

 setaceous lobe bearing several stout angulate chitinous spines and 

 a great many stout setae. Harpes apparently wanting. Basal 

 lobe of harpagones stout, apical portion subtriangular, the latter 

 irregular, consisting of a long, slightly recurved main limb and a 

 smaller, thick inner one. Unci slightlv convolute, terminating in 

 a rotmded dentate apex. [PI. 17, fig. i] 



Stegomyia scutellaris Walk. Genitalia, male. Basal clasp seg- 

 ment stout, gradually tapering to a broadly rounded apex. Termi- 

 nal segment rather long, slender, slightly expanded at the base, 

 more so at the tip and with a very short, stout subapical spine. 

 Llaspette apparently represented bv a thin basal lobe densely
