24. Ceratophyllus endymionis sjiec. nov. (PI. XIV. fig. To). 



This species is closely allied to C. alladinu, but diflers in the following 

 details : — 



Head. — The frontal tootli of the head is less distinct. The small hairs iu 

 front of the eye are much less numerous, and there are two or three small bristles 

 situated near the antenual groove in a transverse row iu front of the three eye- 

 bristles. 



Thorax. — The mesonotum is much more hairy on the back than iu C. allndinis. 

 Tile metanotnm bears several bristles in front of the anterior row. There are 

 one or two short apical spines. The short hairs on the mesothoracical episternum 

 are rather more numerous. 



Abdomen. — The first abdominal tergite bears three rows of bristles and some 

 additional hairs on the back in front of them. The other tergites, except the 

 seventh, have also a few bristles in front of the anterior row. The anterior row 

 of hairs on the seventh tergite is restricted to the back, consisting of five hairs 

 on the two sides together. There are three bristles at the apex of the seventh 

 tergite. The basal sternite of the abdomen bears one ventral bristle on each side 

 and a small lateral hair. The seventh sternite is much less obviously sinuate. 



Legs. — The first hindtarsal segment bears six pairs of bristles on each side 

 and a ventral row of three or four smaller bristles on the posterior (outer) side. 

 The second and third segments bear such a ventral row on each side. The 

 measurements of the mid- and hiudtarsus are as follows : — 



modified Segments. — The eighth tergite (PI. XIV. fig. 70) is much less 

 emarginate at the ajiex than in C. allatlinis. 



Length, 3-4 mm. 



We have two ? ? collected by Mr. J. A. Wolii'sohu at Valparaiso, Chile, from 

 Marmosa elegans. 



This species is also closely allied to C. cidifornicus Baker, but differs from that 

 insect in having the mesonotum much more hairy on the back, the metanotum of 

 C. endymionis having also several additional hairs in front of the two rows. 



25. Ceratophyllus agrippinae spec. nov. (PI. XII. fig. 50. 57 ; XIII. fig. 02. 04). 



Head. — The head is slightly but evenly rounded iu both sexes, resembling in 

 outline somewhat that of the ¥ of Pidcx irrilaiis. On the front there is a groove 

 from which projects a heart-shajied si)ine (PL XIII. fig. 02). The forehead 

 bears two rows of bristles between the antenual groove and the maxillary palpus, 

 the rows being close together, the upper consisting of three or four bristles, the 

 lower of three longer ones. Below the eye, at the antenual groove, there is a long 

 spine-like structure, which is not completely free, being separated from the genal 

 process only by an impressed line. The hinder part of the head bears one bristle
