III. — On some Neiv Parasites. By T. Graham Ponton, F.Z.S., 

 Honorary Secretary Bristol Microscopical Society. 

 Plate XOI. 

 Some time ago I described a new parasite from the tiger, in the 

 pages of this Joui-nal. I now propose to present to its readers 

 four parasites, which I beheve to be hitherto undescribed, or new. 



Menopon ]jtilorhijnclii (mihi) (Plate XCI., Fig. 1). — Colour 

 bright fulvous. Head obtusely subtriangular ; clypeus rotundate, 

 vertex rounded, base concave. Two broad irregular chestnut mark- 

 ings extend from the insertion of the antennae to the eyes, which 

 are connected at that point by a semilunar chestnut line, a chestnut 

 spot in the centre of the clypeus ; prothorax elliptical ; metathorax 

 transverse ; abdomen ovate, hauy ; aU the segments, except the last, 

 have a chestnut spot; legs long, tarsi clavate. Length 2" 115 mil. 

 Habitat, Ptilorliynchus holosericeiis. 



Nirmus Nitzschii (mihi) (Plate XCI., Fig. 2). — This species is 

 probably the same as that mentioned in Griebel's list of the Halle 

 Collection, without either name or description. Supposing this to be 

 so, and that it is undescribed and unnamed, I have ventured to call 

 it Nitzschii, after the indefatigable student of these peculiar insects, 

 C. L. Nitzsch, and beg to give the following description of it : — Colour 

 pale yellowish-white. Head j)anduriform, clypeus rounded, antennae 

 rather long, second joint longest. Prothorax not so wide as the head ; 

 metathorax oblong, trapeziform. Abdomen lanceolate, a long fascicule 

 of hair between each of the four last segments. Legs somewhat 

 clavate. Length 2*538 mil. Habitat, Ptilorhynchus holosericeus. 



Docophorus Dennyii (mih) (Plate XCI., Fig. 3). — This species 

 I have dedicated to the late Mr. Denny, of Leeds, to whom I am 

 indebted for much kind advice and assistance in the study of the 

 Anopleura. Colour tawny. Head triangular, clypeus produced 

 entire; trabeculae large, broadly truncated; antennae rather long. 

 Clypeus bordered by a chestnut line, with a transverse semilunar 

 marking of the same colour, a similar one on the occiput ; a broad 

 irregular chestnut mark extends from the eyes to the prothorax. 

 Prothorax transverse, angles rounded, metathorax transverse. Abdo- 

 men ovate, hairy ; pale fulvous, with a chestnut border. Length, 

 3*173 mil. Habitat, Prismites Mexicanus. 



Trichodectes leporis (mihi) (Plate XCI., Fig. 4). — Colour bright 

 fulvous yellow, a dark chestnut spot at the eyes connected by a 

 diagonal line with a line of the same colour on the occiput. Head 

 suborbicular ; clypeus rounded, vertex convex, lateral margin deeply 

 sinuated ; eyes prominent ; antennae small, last joint broadly clavate ; 

 prothorax transverse ; metathorax not so wide as the head. Abdo- 

 men ovate, fulvous, hairy. Tibiae clavate. Length, 2*538 mil. 

 Habitat, Lepus cannabinus.
