Paragia perkinsi, sp. n. 



2 . Niger ; antennis infra, clypco basi, macula interantennali, 

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

 rufis ; abdomine nigro, segraentis dorsalibus secundo et tertio 

 lateribus apice late, segmento ventrali secundo duabus maculis 

 flavo-rufis; segmentis dorsalibus quarto et quiuto plerumque, 

 segmento sexto omnino flavis ; pedibus nigris, tibiis tarsisque 

 ferrugineis ; alls hyalinis, margine costali infuscato. 



Clypeus subtruncate, as broad as long, somewhat produced 

 towards apex ; head as broad as thorax ; mesonotum with 

 two small tubercles on tlie 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. The 

 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. Peikins, by whom all three new species were presenteii. 

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

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

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

 species in which the whole thorax with the exception o£ the 

 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 AIj)ha, Dalla Torre), 

 whereas the first abdominal segment in the nearly allied 

 species is distinctly narrower than the second, and divided 

 Irom it by a constriction (group BetUj Dalla Torn). P. pter- 

 kinsi is a larger insect. 



LXXXVII. — Some probable and possible Instancesof Warning 

 Characteristics amongst Insectlcorovs and Carnivorous 

 Matnmals. By 11. I. POCOCK, F.K.8. 

 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.
