ERYCINA. 393: 
femur=1 coxa, tibia=coxa, tarsus (single-jointed)=% tibia. The terminal tarsal joint 
of the front leg of the female is longer than either of the three preceding joints, and 
has a setose pad beneath ; the first four joints terminate beneath with a pair of strong 
“spines. 
The terminal joint of the palpi is short =+ middle joint, it is dilated towards its base 
but tapers towards its distal end; the basal joint is short, slightly longer than the 
terminal joint. Antenne have fifty-two joints, of which the terminal eighteen form 
a moderate club. 
The secondary male organs have the tegumen normal; the harpagones are bilobed, 
slightly setose externally ; a strap proceeds from near the end of the penis, is directed. 
outwards between the harpagones, and is then bent abruptly backwards to their base. 
The penis itself is swollen towards the base, slightly decurved and pointed towards 
the extremity, whence apparently proceed several filaments furnished with chitinous 
papille. ‘The bursa copulatrix of the female has a pair of chitinous spines, smooth, 
and of the shape of mamme.

Alis nigricante-fuscis, fascia communi mediana punicea in posticis ad marginem internum refracta et ultra eam 
macula ejusdem coloris ; posticis fascia maculosa angusta viridescente micante (in anticas interdum pro- 
ducta), angulo ipso letissime czruleo ; subtus nitidissime ceeruleo-viridescentibus marginibus et fascia com- 
muni lata mediana nigerrimis, macula ad medium posticarum marginis interni coccinea, macula altera infra 
~ eam et ciliis inter venas albis; cruribus anticis nitide ceeruleo-viridescentibus fusco ciliatis. 
2 multo major, alis fuscis albo bifasciatis, fascia interna latiore et utraque coccineo terminata ; posticis macula 
ejusdem coloris ad angulum analem, utraque maculis albis, lutra eas ceruleo micantibus ; subtus fere ut 
supra, fascia externa alba magis distincta.

The late Mr. Wilson Saunders described the female of this species as E. jurgensent, 
and in the same paper the male as E. montezwma, at the same time suggesting that 
they were sexes of one species, a surmise we believe to have been fully justified. We 
have no specimens from Mexico whence the types were derived, but we recognize the 
species in our examples from the rest of Central America, and note the distinction 
between them and Colombian specimens, the true E. atahualpa of Saunders. These 
_ differences are very slight, but, so far as we can see, constant. There is a red spot at 
the anal angle of the secondaries not seen in E. atahualpa; the blue submarginal spots 
of the secondaries are smaller. 
E. jurgensent is nowhere common ; a specimen or two from each of the above localities 
are all we have seen.
