198 A. e. OUDEMANS, NOTES ON ACARI. 



Canestrini (1878) says of his mite : 



»T due corna . . . presso l'apice si curvano alquanto in dentro.« 



»Il margine interno del seno succitato porta due lamiiiette 

 diafane che ne restringono l'ampiezza, e la punta di ciascun 

 corno ha pure una lamina diafana, il cui margine posteriore 

 è tridentato.« 



»I dixi adesivi distanto l'uno dall' altro due a due a mezzo 

 de' propri diametri, e sono posti presso la linea transversale 

 che tocca la sommità del seno.« 



»lia femmena ha il margine posteriore del corpo assai 

 legermente inciso, e porta su di esso quattro lunghe setole, 

 due cioè per parte. Essa manca e lamine chitinose ; nel resto 

 concorda col maschio.« 



In 1879 Canestrini gives no description of the species, but 

 only presents a drawing of the male. Here we observe that 

 the »horns« not only are »presso l'apice si curvano alquanto 

 in dentro«, but in fact are curve considerably in their whole 

 length. Internally there are two hyaline blades, one on each 

 side ; these blades do not reach the top of the excavation, 

 nor the end of the horns. These bear distally a hyaline piece, 

 of which really »il cui margine posteriore è tridentato.« The 

 anal suckers really are placed behind the line which goes 

 trough the top of the excavation. The epimera I form a V 

 (which may be an error). Legs 111 and IV are rather slender. 



Trouessart (1885) gives no description, nor a drawing. 



Finally Canestrini's (1886) description is verbally the same as 

 that of 1878. His figure 4 is a representation of the male. The 

 horns are curve. The representation of the internal and distal 

 hyaline blades is the same as that of 1879. But the anal 

 suckers are drawn more forward. Their centres are on a 

 line that goes through the top of the excavation. The epimera I 

 form a V (which, I am sure, is an error). Legs III and IV 

 ai-e equal to I and II, consequently better represented that in 

 the drawing of 1879.
