PROTOMAGALH^NSIA. 103 



Ijroad, widest at its middle and gradually narrowing towards 

 the rounded posterior end. Nucleus large and spherical or 

 somewhat oval, and usually placed about the middle or a little 

 in front of it, with a distinct nuclear membrane and one or 

 tAvo karyosomes. Length of protomerite to total length as 

 1 : 3'3-4*0 ; width of protomerite to width of deutomerite 

 as 1 : 1-2-1 -5. In the sporonts the protomerite is consider- 

 ably reduced in proportion to the total length of the body. 

 Length of protomerite to total length as 1 : 6 ; width of pro- 

 tomerite to width of deutomerite as 1:1-6. Sporonts bi- 

 associative. Sporonts forming association are much more 

 elongate than cephalonts. Gametocysts spherical. Sporo- 

 cysts ovoid or nearly spherical. 



Dimensions. — Sporonts 40-142 yu. in total length ; gameto- 

 cysts about 90 ju. in diameter ; sporocysts 12 /x. in diameter. 



Remarks. — The epimerite, though presenting a crenated 

 surface, cannot be regarded as complex ; it varies in appear- 

 £ince and ultimately .becomes simple and symmetrical. The 

 protomerite resembles that oiPyxinoides balani and P. cthamali 

 {vide Tregouboff, 1912), but the epimerite differs from that of 

 Pyxinoides, which is described as a style dilated in the middle. 

 Ray and Chatter] ee (1936) have recently studied this parasite 

 from the same host at Calcutta, and are of opinion that the 

 cauHflower-like appearance of the epimerite is due to the 

 action of the fixative or some other disturbing factor. Their 

 observations have not yet been pubhshed in full. 



Habitat. — ^Ahmentary canal of the beetle Aulacophora 

 foveicollis Kust. i=^A. abdominalis G. et H.) : Punjab, Lahore 

 and Kalka ; Bengal, Calcutta. 



Genus PROTOMAGALH^NSIA Pinto, 1918. 



Proto'inagalhaensia, Pinto, 1918 ; 1923, pp. 90-91 (translation, 

 pp. 25-6), pis. iii, fig. 48, &vi, fig. 93; Kamm, 1922, p. 11; Setna& 

 Bhatia, 1934, pp. 38-42. 



Sporonts in associations of two to several individuals, 

 often attached laterally. Sporonts attenuate. Myonemes 

 prominent. Epimerite unknoAvn. Gametocysts unknown. 

 Sporocysts barrel-shaped, Avith a spine at each corner. 



Remarks. — In addition to the characters given above, 

 Pinto (1923) mentions in the diagnosis of the genus that the 

 development is always intracellular, and that in the syzygies 

 the protomerite of the satelhte embraces the deutomerite of 

 the primite, like a pair of forceps. As he places the genus in 

 the family Gregarinidae Labbe, in which the development is 

 extracellular, the word " intracellular " is probably a mis- 

 print for extracellular.
