Tipula ingrata spec. n. (Plate XIII, figs. 9, 10 and 11 ; plate XI\', fig. 4.) 



Color yellowish gray; wing markings not pronounced. Lateral append- 

 ages with two chitinized processes, the lowei- of v/hich is clawlike. 



d^, Length, 13.5 mm.; wing, 16 mm. 



Anterior leg: femur, 8.5 mm., tibia, 10 mm., tarsus, 13.5 mm. 



Head yellow; occiput gray with ill-defined median fuscous line and short 

 black hairs each side behind the eyes; face whitish pollinose. Rostrum 

 yellow, nasus brown towards the apex, beset with short black hairs. Palpi 

 sordid yellow, second joint longer than the third, fourth joint scarcely 

 longer than the two preceding joints together, the whole palpus beset with 

 rather long scattered blackish hair. Antennae slender, bent back they 

 reach to about the middle of the metanotum, scape yellow, flagellum pu- 

 bescent, brown, the first joint yellow, infuscate towards the apex, segments 

 slightly thickened at base and beyond the middle, each with four or five 

 basal setae. 



Thorax: CoUare pale, anterior margin and median longitudinal line 

 fuscous. ]\Iesonotum grayish brown, lateral stripes concolorous, broadly 

 margined with fuscous, middle stripe brownish, wide and but little nar- 

 rowed posteriorly, the median dividing line widening beyond the middle 

 and occupj'ing the greater part of the stripe; the spaces between the stripes 

 beset with fine pale pubescence; no marking behind the transverse suture; 

 scutellum and metanotum yellowish gray with median fuscous line. Pleura

 emarginate each side and slightly projecting in the middle, and from its 

 underside projects a strongly chitinized, black process ending in two claw- 

 like, divergent teeth; ninth sternite with median chitinized suture, posterior 

 margin broadly emarginate, and from its middle arise two bladelike proc- 

 esses, their basal portion strongly curved backward, the apical portion 

 straight, tapering. No pleural suture. Upper apical appendage broad, 

 leaflike, obtusely rounded at apex; the middle appendage consists of an
