278 Records of the Indian Museum. [Vol. IV, 



Described from one 9 from Kurseong, November, 1910, taken 

 by Mr. D'Abreu. 



Type in Indian Museum. 



Note. — This species must bear a considerable resemblance at 

 first sight to Bibio venosus, Meig., owing to the rather clear wings, 

 the distinctness of the veins, and the similarity in size. Though 

 the abdomen is given as only a little over 5 mm. in length, it is 

 probably more in Hving specimens . as the single example examined 

 appears to be shortened by shrinkage ; otherwise the wings 

 are abnormally long, their full expanse being 20 mm. The 

 relative length of the hind metatarsus to the following joint is 

 practicalh^ identical in both species, and it is quite possible the 

 specimen before me really is a variet}' of venosus, Meig., bearing 

 about the same relation to it as obscuripennis does to marci, the 

 onh" suggested differences in mj' new species from venosus being 

 the grey instead of clear wings, and the pale yellow instead of 

 whitish colour of the abdominal pubescence.

Described hom. two 9 9 from Phagu, Simla district (9,000 ft.), 

 ii-v-09, taken by Dr. Annandale. 



Type in Indian Museum. 



Note. — This species has considerable resemblance to B. johan- 

 nis 9 , but the distinctly yellowish thorax with well-defined black 

 dorsum at once distinguish it from the European species, in which 

 the whole thorax is black or blackish brown. 



Bibio johannis, L- 



Two males, taken by Dr. Annandale at Matiana, 28— 30-iv-07, 

 and another from Theog (9,000 ft.), 2-V-07 (both places, Simla 

 district), certainly represent this well-known European species.
