Life-liistorij . That of the common Indian C. heminojila.^Wedi., 

 has been worked out at the Pusa Institute. 



Some confusion has arisen over the name Clitellavia. Verrall 

 notes that it was established by Meigen in 1803 for ephi2^2)ium, F., 

 and that that author subsequently (1822) enlnrged the scope of 

 the genus, including in it vUlosa., F., calva, Mg., aiid/>aci/tcrt, Hfg., 

 as well as ephipphim^Y. Latreille in 1804 erected hypliippium iov 

 the species of that name,* and, as was customaiy in those days 

 in such cases, changed the specific name to thoracicum to avoid 

 redundancy. Therefore the name CUtellaria must stand for the 

 remainder of the species placed in it by Meigen or, at tlie very 

 least, for one of them. C. pacijiea is an Odontomyia and synony- 

 mous with Ihnhata, Wied., which leaves only villosa and calva, one 

 of which should be the type of CUtellaria, Mg. Kertcsz retains 

 Meigen's original sense of the genus {i.e., for ephlppium, F.) in 

 his Kat. Dipt. (1908), but adopts the inadmissible name Potamida 

 (Mg. 1800) for it. Meigen added dalilii in 1830 to CUtellaria ami 

 Kertesz has renamed this group of species Adoxomyia. Lasiop>a, 

 Brulle (1832), differs from CUtellaria, Mg., in having an nnspined 

 scutellum, and both villosa and calva have been placed in it. 

 Therefore CUtellaria, as understooil by Meigen, was by this time 

 reduced to the single species dahlii, and this species is designated 

 by Bezzi as the genotype. Kertesz's '■'■Potamida, Mg." must con- 

 tinue to be known as Epliippnum, Latr. ; Adoxomyia, Kert., is the 

 true CUtellaria, Mg., and must retain this latter name; and Lasiopa, 

 Brulle, is a good genus. 



The two Indian species are separated thus : — 



Thorax without definite hair-stripes, but with a 

 darker median stripe surrounded by four spots 

 arranged in a square Jieminojyla, Wied. 



Tliorax with two distinct stripes of short golden- 

 brown hairs bistriata, Brun.
