(^ . — Similar in inost respects ; mandibles redder; liair of 

 face all pale yellowish ; cheeks with a bare space below. 

 Lei^s bright chestnnt-red ; anterior coxce with well-developed 

 but blunt spines ; venter of abdomen red; fifth abdominal 

 segment without lateral spines, sixth with six, the lateral and 

 lower apical ones very slender and sharp, the upper apical 

 shorter and thicker.

 June, 1915. 



The female is marked "near igaava, Sm., notinB.^I.'^ The 

 males, "uo name 13. M.'" In Friese's table (1921) of Brazilian 

 species this runs (?) to G. leopoldensis, Fr., but the last 

 ventral is much less produced, and the legs are much darker. 

 It also resemiiles the Brazilian C. nigrofunbriata, Ckll., but 

 is easily distinguished by the end of the abdomen. In 

 Holmberg's table (1903) it falls with C. remissa, Holmbg., 

 from the Argentine. It goes in Holmberg's group Melano- 

 basis, and in the subgroup (1917) with densely punctured 

 scutellum, which includes seven of Holmberg's Argentine 

 species. Unfortunately I possess none of these seven 

 species, but I believe the present insect is distinct from all. 



XLIV. — A new Ascarid from an Otter.

Among helminthological material recently collected by 

 Mr. A. Loveridge in Tanganyika Territory' there occurred 

 two sets of specimens of a very curious Ascarid which seems 

 to represent a new genus, having, however, close affinities 

 with Contj'accecuni. One set of material, including both 

 sexes, came from an otter {Lutra sp., probably L. maculi- 

 collis). The other contained only three females, and was 

 taken from the stomach of a mongoose [Atilax paludinosus, a 

 species wdiich inhabits swamps). The following description 

 is based on the former specimens, which are taken as types. 

 The females from the mongoose are slightly larger than the 

 type-females. In both cases the locality was Kilosa.

 40"5 mm. long and the largest female 38"7 mm. The greatest
