short, none of them being essentially louger thau the tergite itself. The stylet 

 is subconical, being about three times as long as broad. 



Length : c?, 3-2 mm. ; ? , 4 mm. 



We have seven examples of this species, as follows : — 



2 c?cf, Santa Cruz, Brazil, 1897. Canis griseus. 



Collected by Dr. Ihering. 



The c? referred to by Baker, I/;., as being that of (jrossiccntris belongs most 

 probably to this sj^ecies. 



3. Malacopsylla agenoris spec nov. (PI. VII. fig. u. 0. 7. 8. 9 ; VIII. fig. 13). 



Head. — The head is similar in the two sexes. It is punctured above and is 

 evenly rounded in front, being without a frontal tubercle (PI. VII. fig. 7). There 

 are two bristles in front of the eye, and two short blunt spines. The ventral 

 edge is rotundate-angulate just behind the maxillae, and then horizontal as far 

 as the antennal groove. The occiput bears an oblique series of bristles behind 

 the insertion of the antenna, three bristles farther back above the antennal groove 

 situated in a triangle, the most ventral one being very long, and moreover some 

 dorsal subapical bristles. The row of fine hairs above the antennal groove does 

 not extend to the point where the antennal groove bends upwards. The first 

 and second segments of the maxillary palpus are nearly the same in length, 

 while the third is shorter and the fourth longer. The rostrum is shorter than 

 the maxillary palpus, reaching barely half-way down the forecoxa when this is 

 perpendicular in position. The end segment of the rostrum is less than half as 

 long again as broad, while the three preceding segments are twice as broad as long. 



Thorax. — The pronotum is very short (PI. VII. fig. 7, pnt.). It bears close to 

 the base a row of bristles, and at the apex a comb of six broad, short, blunt teeth 

 which stand far apart. The meso- and metanotum bear each one row of bristle.s, 

 the metanotum being shorter than vertically broad (on the slide). The mesonotum 

 bears a row of very thin hair-like spines near the apex. The epimerum of the 

 mesothorax bears one bristle near its upper edge and another farther down at the 

 hinder edge. The epimerum of the metathorax bears three or four bristles from 

 the stigma downwards. It is produced, like the epimerum of the pro- and 

 mesothorax, into a small rounded lobe at the hinder edge (PI. VII. fig. 5). 



Abdomen.— On the abdominal tergites there is one row of bristles. Between 

 the first and second bristles there are two very fine hairs, this being the case also 

 with some of the other bristles, especially on the posterior segments of the S. 

 The wide interspace and the presence of two small hairs in one interspace shows 

 that some of the bristles have become obliterated in this species. The apical 

 bristle of the seventh tergite is slender and rather short, not being longer than 

 the ventral one of the seventh tergite. The stigmata are large and stand between 

 the first and second bristles. The pygidial plate is transverse. The anal tergite 

 is nearly scmicircnlar. The stylet of the ? is very short, and the anal steruite 

 distinct also in the cJ. The liasal steruite bears in the S one or two, in the ? 

 four to six, short and thin hairs on the side. The steruites of segments 3 to G 

 have two ventral bristles on each side. The sternite of the seventh segment 

 has in the S two bristles, while in the ? it is small and triangular, bearing two 

 or three bristles. The abdomen of the ? is distended.
