2. Phrictus quinquepartitus, n. sp. (Tab. IV. figg. 8, 8a, 83.) 
¢. Head castaneous, the prolongation armed on each side with two pairs of spines arranged one above the 
other, with their apices fuscous, the apex recurved as in P. diadema, but furnished with five spines or 
angles, the central longest; this prolongation terminates posteriorly behind the eyes in a long, suberect 
and posteriorly directed black spine on each side, with their bases deeply excavated ; beneath is a central 
rugosity, on each side of which it is deeply excavated. Pronotum pale castaneous, with a prominent 
central longitudinal carination, on each side of which it is distinctly foveate, and with the lateral angles 
acute and ornamented with a broad black fascia on each side. Mesonotum ochraceous, tinged with 
fuscous, with three black spots, one near each anterior angle, and one larger and less well defined near 
apex. Abdomen above black, with the base more or less suffused with a white waxy excrescence, and with 
the apical margin pale castaneous. Body beneath ochraceous, suffused with fuscous ; the legs fuscous, 
with the knees castaneous; posterior tibie armed with a series of five spines, and with an irregular 
cluster of spines at apex. Tegmina bright castaneous, crossed by a waved subapical fascia, bifurcate 
posteriorly, and inwardly white and outwardly pale obscure ochraceous ; and more or less margined on 
each side with black ; before this fascia the veins are greenish ochraceous ; and beyond are a number of 
greenish ochraceous suffusions ; a costal series of black spots, an obscure outer submarginal black line 
preceded by some small spots of the same colour. Wings with the abdominal area pale fuscous, and with 
the reticulated veinlets greyish ; basal area red, marked with some large irregular blackish spots and a 
few minute whitish spots ; apical area blackish, with a few very pale bluish spots. 
Long. ¢ 30 to 34 millim., 9 37 to 41 millim., exp. tegm. ¢ and @ 68 to 80 millim. 
Hab. Panama (Boucard), Volcan de Chiriqui 3000 to 4000 feet, Bugaba (Champion). 
—CotomBia, Bogota (Chesterton, coll. Dist.). 
This species is at once structurally differentiated from both P. diadema and 
P. ocellatus by the five-spined lobate apex of the prolonged head.
