only of one male and one female, the sectors of the triangle are a 

 little separated at their origin. 



Previously known from Turkestan (Selys). 



13. Sympetrum (or Diplax) vulgatum L. 



One male, " 5-10,000 f.", has the black longitudinal line on each 

 side of the third abdominal segment, the basal line of the frons pro- 

 longed iuferiorly in front of the eyes,hamules as described by Baron 

 de Selys (Ann. Soc. Ent. Belg., xxxi, p. 10). It is of the typical 

 form of vulgatum and not of the race decolorata Selys. 



14. Sympetrum (Diplax) Fonscolombii Selys. 



One male, two females " 5-10,000 f." ; one female " below 5,000 

 f." In the male, which is semi-adult, the yellow on the base of the 

 hind wings reaches out in the submedian space almost to the tri- 

 angle and more than half way back toward the hind margin. In 

 the females the extent of this yellow is smaller and like that of 

 European examples. 



Previously known from Turkestan, and Murree in N. W. India. 

 Mr. C. C. Adams and Prof. M. J. Elrod have sent me both sexes 

 from the plateau of the Nilgiris, 7,500 ft., taken in August and 

 September, 1896. 



15. Sympetrum (Diplax) meridionale Selys. 



One female, " below 5,000 f." There is a greater extension of 

 yellowish coloring over the bases of the wings than is usual in Euro- 

 pean individuals of this species, but the other characters agree. 

 Baron de Selys refers to this species a female from " les montagnes 

 de lTnde." (Ann. Soc. Ent. Belg., xxviii, p. 36, 1884).
