description. The specimens from Gamangui, Basoko, and ]\Iedje 

 agree very closely with each other in every particular and have a facies 

 which is somewhat different from the specimens taken at Faradje. 

 When an analysis of the facts is made, however^ it clearly appears that 

 the only real difference is due to the uniform enlargement of the various 

 spots upon the wings. As Neave points out, this insect is a close mimic 

 of Pardopsis pundatissima. This is particular!}^ true of the specimens 

 with the enlarged spots. From P. pauJi Staudinger the insect may be 

 discriminated by the fact that the elongated marginal spots, one in each 

 interval of the upper and lov/er wings, do not entirely reach to the margin, 

 as they do in P. pauli (cf. Rhop. iEthiopica, p. 261. where Aurivillius 

 has given us a figure of that species), but constitute a distinct and regular 

 submarginal series, separated from the thin marginal line by an appreci- 

 able interval. Many of the spots are, as Neave points out, "monili- 

 form," — I should say having the shape of a dumb-bell, especially in the 

 apical region of the fore wing. The species is in my judgment valid and 

 not to be confounded with P. pauli, which in size and general appearance 

 it somewhat reseml^les. I discover that we have a series of fineb/ 

 preserved specimens of the species from the interior of Cameroon, collect- 

 ed some years ago by Mr. A. I. Good and awaiting a convenient season 

 for its study, which the arrival of the Lang-Chapin material has created. 



(335) 2. Pentila cloetensi Aurivillius (?) 



Plate XII, Figure 9, d"

In the markings of the fore wing agreeing entirely with the descrip- 

 tion and figure of P. cloetensi given by Aurivillius, but quite different in 

 the form and arrangement of the spots on the outer border of the hind 

 wing. In the specimens before me the marginal row of spots on the 

 secondaries arc located at the tips of the veins and are quite large, 

 sagittate, pointing inwardly and running for some distance along the 

 nervules basad, much as in P. aiiga Karsch, or in some heavih' marked 

 specimens of P. abraxas Doubleday and Hewitson. I refer the specimens 

 provisional^ to P. cloetensi Aurivillius, with which they agree more 

 closely than with any other species, realizing that there is in this genus 

 more or less variabilit,y in the number and size of some of the markings, 

 as is shown by long suites of many of the species in my possession. It is a 

 doubtful procedure to erect species in the genus Pentila, basing them 

 upon the presence or absence of some of the spots, or their size 



The collection contains two males taken at Medje, one in August, 

 the other in September.
