Parasitus cappa Oudms. in Entom. Bericht, no. 17, p. 153, 

 1 Mei 1904. 



Deutonympha. Among numerous P. coleo ptratorum (L.), 

 deutonymphae, found on Geotrypes stercorarius L. at Sneek in 

 1896, an individual, apparently a deutonympha oï coleopti'atorum 

 (L.), but even with the naked eye discernible as considerably 

 larger, arrested my attention. After carefull examination it 

 proved to be of a different species. 



Length 1320 jw; anterior dorsal shield 750 m long, 750 

 ia wide; posterior shield 375 ß long, 705 jj. wide; mandible 

 600 fj. long. Colour, shape, texture like in P. cole- 

 optratorum [L.). Dorsal side (fig. 39) protected by two 

 shields. Anterior shield (the single specimen in my collection 

 is a little compressed) trapezoidal, wider posteriorly, with 

 rounded angles and sides. Posterior shield semicircular, with 

 anterior edge slightly concave. Tbe shields are separate by an 

 unprotected band, and surrounded by an unprotected margin, 

 which is wider posteriorly. Hairs on the usual places and 

 of the same kind as in P. coleoptratorum (L.)\ fig. 41 represents 

 one of the dorsal rod-like hairs; only with this exception, 

 that the pair of rod-like distally hairy hairs on the posterior 

 edge of the postorior shield are planted here far more inward; 

 not on the edge; and that between this pair there is a pair of 

 strongly developed bristles. 



Ventral side. Tritosternum (fig. 42) slender, 

 with wide base, two triangular minute transparent wings 

 laterally of the main trunk between its second and third 

 third .part, a pair of ditto quite distally on the rounded and bifid 

 top, on the two lobes of which are implanted the flagellae. 

 The tritosternum is planted itself on a tritosternal 

 shield (see also p. 34, in the description of P. coieop-
