jointed apical style, 1st very short, 2nd long. Thorax elliptical, 

 moderately arched ; scutellum with two spines, often small and 

 indistinct. Abdomen a little broader than thorax, oval or elliptical, 

 rather well arched, 5-jointed ; genitalia small. Legs moderately 

 long and strong. "Wings with normal venation ; 3rd vein distinctly 

 forked, 4th vein with three endings; posterior cross-vein abseni, 

 as upper branch of 5th vein forms part of lower side of discal cell. 



Range. Europe, Western Asia, North Africa, Orient, North 

 America. 



Life-history. That of the common Indian 0. heminopla, ^\ied., 

 has been worked out at the Pusa Institute. 



Some confusion has arisen over the name Clitellaria. Verrall 

 notes that it was established by Meigen in 1803 for ephippium, F., 

 and that that author subsequently (1822) enlarged the scope ot 

 the genus, including in it villosa, F., calva, Mg., and pacifica, Hfg., 

 as well as epliippium,T?. Latreille in 1804 erected Epliippium for 

 the species of that name,* and, as was customary iu those days 

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

 redundancy. Therefore the name Clitellaria must stand for the 

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

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

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

 of which should be the type of Clitellaria, Mg. Kertesz retains 

 Meigen's original sense of th*e genus (i. e., for ep7iippium, F.) in 

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

 (Mg. 1800) for it. Meigen added dahlii in 1830 to Clitellaria and 

 Kertesz has renamed this group of species Adoxomyia. Lasiopa, 

 Brulle (1832), differs from Clitellaria, Mg., in having an unspined 

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

 Therefore Clitellaria, as understood 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 Ephippium, Latr. ; Adoxomyia, Kert., is the 

 true Clitellaria, 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 heminopla, Wied. 



Thorax with two distinct stripes of short golden- 

 brown hairs bistriata, Brun.
