630 On new Crane-flies from New Zealand. 



Type ^ , allotype ? , and paratypes (^ ? in the British 

 Museum. 



The only other New Zealand species with the type of 

 abdominal markings found in this interesting new form are 

 M. tenera (Hutton) and M. pseudoteneraj Alex. With the 

 latter of these M. bivittata agrees in most respects, but differs 

 in its shorter antennae and longer Rs. From tenera it differs 

 obviously in the dark marking on the head, four prsescutal 

 stripes, markings of postnotum, etc. 



MacromastLx elongata^ sp. n. 



Head almost uniformly orange-brown, slightly dusted with 

 grey at the sides behind the eyes. Pubescence fine and pale. 

 Front not much more than half as broad as one eye. Frontal 

 tubercle rather large, slightly but distinctly bifid at the tip. 

 Rostrum about as long as the head, orange-brown, somewhat 

 darker beneath. Nasus long, clothed with conspicuous long 

 golden hair. Antennse with the scape ochreous, flagellum 

 black ; first six flagellar segments distinct and equal in 

 length, though decreasing slightly in diameter, the terminal 

 four segments very slender and indistinctly separated. 

 Thorax : pronotum dark brown at the sides, greenish brown 

 in the middle, pale posteriorly. Mesonotum with scarcely 

 perceptible pubescence, ground-colour dull greenish. Prse- 

 scutum with four brown stripes, the margins of which are 

 darkened, middle pair of stripes almost contiguous. Scutum 

 with two broad brown stripes. A blackish spot in the middle 

 of the suture. Scutellum brown, sides narrowly greenish. 

 Postnotum and pleura dark brown, heavily dusted with grey, 

 the pleura with two ill-defined almost black spots. Abdomen 

 rather elongate, dark brown, somewhat shining, the posterior 

 and lateral margins of the tergites narrowly pale. Ovipositor 

 long, but fleshy and hairy as in the genus. Legs very long, 

 coxae coloured as pleura, remainder of legs uniformly rather 

 dark ochreous. Wings very slightly milky, cells G and So 

 orange-brown, stigma rather elongate, blackish, with a very 

 small pale spot at each end, veins brown. Venation : Rs 

 short and straight, a little shorter than i?2+3« -^2 oblique, 

 almost continuing the direction of i^2+3 ^i^d nearly half as 

 long as this vein. Petiole of cell Mi 1 ather shorter than m ; 

 m-Gu obliterated ; cell Ax rather broad. Halteres with dark 

 stem and greenish knob. 



Length of body 25 mm,; wing 25x5*5 mm.; hind 

 femur 13'5 mm ; hind tibia 15 mm. ; hind tarsus 22 mm. 



Type ? (unique) in Mr. Hudson's collection.
