750 Mr. R. I. Pocock on Warning Characteristics 



Paragia perhinsi, sp. n. 

 5 , Niger ; autennis infra, clypeo basi, macula interantennali, 

 oculis margine interno, macula postoculari, pronoto angulis, flavo- 

 rufis ; abdomine nigro, segraeutis dorsalibus secundo eb tertio 

 lateribus apice late, segmento ventrali secundo duabus maculis 

 flavo-rufis; segmentis dorsalibus quarto et quinto plerumque, 

 segmento sexto omnino flavis ; pedibus nigris, tibiis tarsisque 

 ferrugineis ; alls h3'alinis, margine cos tali infuscato. 

 Clypeus subtruncate, as broad as long, somewhat produced 

 towards apex; head as broad as thorax; mesonotum with 

 two small tubercles on the disc; scutellum prominent, nar- 

 rowing somewhat posteriorly, median segment with a con- 

 spicuous tubercle on each side, surface of truncation of 

 median segment with two shallow parallel furrows. 



First abdominal segment not constricted at apex. Tlie 

 whole covered with a sparse fulvous pubescence, most con- 

 spicuous on the legs. 



Punctured, head, thorax (except median segment and 

 postscutellum) coarsely ; postscutellum, median segment 

 (both laterally and on the surface of truncation), and first 

 abdominal segment more finely, remaining abdominal seg- 

 ments very sparsely punctured. 



Length 12^ mm. (to apex of second abdominal segment).

 I have much pleasure in naming this species after Dr. R. 

 C. L. Perkins, by whom all three new species were presented. 

 The species comes into my key to the genus (Ann. & Mag. 

 Nat. Hist. (8) V. p. 31, 1910) after A. h\ the most nearly 

 allied species being P. odgneroides and P. hidens, the two 

 species in which the wliole thorax with the exception of tiie 

 pronotal angles is black. P. perkinsi differs from them in 

 having the first abdominal segment at apex as broad as the 

 second abdominal segment at base (group Alpha, Dalla Torre), 

 whereas the first abdominal segment in the nearly allied 

 species is distinctly narrower than the second, and divided 

 from it by a constriction (group Beta, Dalla Torre). P. per- 

 kinsi is a larger insect. 



LXXXVII. — Some probable and possible Instances of Warning 

 Characteristics amongst Insectivorous and Carnivorous 

 Mammals. By R. I. PocoCK, F.R.S. 

 The views put forward in the following pages are an 

 extension of those I have already published in the ' Pro- 

 ceedings of the Zoological Society ' * on warning attributes 

 in porcupines and musteline carnivora. 



* P. Z. S. 1906, p. 902 (on porcupines) ; 1908, pp. 944-959 (on 

 musteline carnivora) ; 1911, ]>p. .559-560 (on Fntorius nigvipes).
