ver)' slender, ami is slightly ililatcd at the apex. Tlie ninth sternite (ix. st.) is 

 broad; it is siunate beyond the middle, with the distal angle of the proximal 

 portion somewhat projecting distad. 



Length : 3, 3-7 mm. 



We have one S of this species from the Benito River, Spanish Gaboon, 

 collected by Mr. W. Bates. The host is not known to us. AVe are indebted to 

 Mr. W. de Winton for the specimen. 



Macropsylla gen. nov. 



?. Closely allied to Hi/strichopsylld. The rostrum consists of eleven to 

 thirteen segments in the only species known. There is a row of spines situated 

 along the ventral edge of the head as well as along the antennal groove (PI. XIV. 

 fig. 9). The eye is vestigial, situated at the base of the uppermost spine. The 

 chitiu of the occiput is internally thickened in the middle, as indicated in the tignre. 

 The episternum of the metathorax is about twice as long as it is broad. The fifth 

 tarsal segment has four lateral bristles, besides a thin snbapical hair, and a ventral 

 pair of bristles in between the first lateral pair. There are two bursal copnlatrices, 

 as in ni/strichoii.vjUa. The eighth sternite is absent, while the tergite is completely 

 divided dorsally in the mesial line. 



The posterior angle of the gena, underneath the antennal groove, has developed 

 into a spine (PI. XIV. fig. 8). This spine corresponds to the posterior row of gcnal 

 spines met with in StephanocirciM, while the coutinnous row of spines extending 

 in MacropiijUa from the anterior oral corner to the vestigial eye is homologous to 

 the row of spines situated along the hinder edge of the helmet in Stephanocircus. 



T. Macropsylla hercules spec. nov. (PI. XIV. fig. '.», ](i). 



Head. — The frons (PI. XIV. fig. 9) is quite different in outline from that of 

 Hi/stricliojisylla, being rounded as far down as the first genal spine. There are six 

 genal spines at the ventral edge and three at the edge of the antennal groove. 

 The genal process beneath these spines is also armed at the apex with a short 

 broad spine. The frons bears seven long bristles, and is covered, moreover, with 

 numerous short hairs. The occiput bears four rows of bristles, and above the antennal 

 groove a row of short hairs. The space in front of and above the first row of 

 bristles is punctured. The rostrum does not quite reach to the apex of the forecoxa. 

 The maxillary palpus is much shorter than in //. talpnc, but the proportional length 

 of the segments is about the same as in that species. 



Thorax. — The jironotum bears three rows of bristles and a comb of twenty- 

 eight to thirty-four sjiines, besides some additional bristles in front of the first row. 

 The mesonotum is very hairy, bearing four rows of bristles and unmerous shorter 

 hairs situated between these rows and the base. There are dorsally before the apex 

 two long slender spines on each side. On the sternum of the mcsothorax there are 

 about thirty bristles, most of them standing in the upper half, and there are about 

 eighteen on the cpimerum. Tlie metanotum bears four rows of bristles. There are 

 two vertical rows of bristles on the episternum, with two additional bristles in front, 

 the ejiimcrum bearing about twenty-seven bristles, the middle and jKtsterior ones 

 being arranged in two vertical rows. 



Abdomen. — There is a comb on segments 2 to o, the first three combs
