3. Bolbonota pictipennis. 
Bolbonota pictipennis, Fairm. Aun. Soc. Ent. Fr. sér. 2, iv. p. 258°.

This species, of which we have received a large series from Chiriqui, appears to be 
very variable in size and to a certain extent in sculpture and in the colour of the 
tegmina. The largest specimens are about 34 millim. in length; they are dull black, 
fuscous-black, or brownish insects, with the dorsum, if viewed from the side, almost 
straight until just before the apex, where it is abruptly depressed. The elytra are 
dark, with yellow or whitish spots, and with the apex distinctly hyaline; in one 
example from Panzos in Vera Paz the yellow colour covers the whole centre of the 
tegmina, and the dorsum is less abruptly depressed than is usual with the species. 
On an examination of typical specimens from Signoret’s collection I have little doubt 
but that B. nisus, Germ., and B. pictipennis, Fairm., are identical; if this is the case, 
the first name must be adopted. As, however, Signoret’s specimens are somewhat 
broken and imperfect, I prefer to leave the species as they are for the present. 
Walker’s Tetraplatys atomarius (List of Homopt. Ins. ii. p. 510) is either this or a 
closely-allied species. 
Var. levior. 
Minor, levior, minus rugosa, apice pronoti evidenter magis prolongato. 
Closely allied to the type form, but differs in being smaller and less rugose, with the apex of the pronotum 
evidently more prolonged. 
Long. 24-3 millim.; lat. max. 2 millim. 
Hab. Panama, Volcan de Chiriqui, Bugaba (Champion). 
It is possible that this may be a distinct species, but in the large series of the type 
form and the variety from the Volcan de Chiriqui the gradations are so regular that it 
is very difficult to divide the variety from the type, although no one would hesitate in 
describing the extreme examples as distinct. The smallest examples are only about 
24. millim. in length. 
Besides the examples above referred to there are two specimens from San Juan in 
Vera Paz (Champion) which appear to belong to this variety, although they differ 
slightly in one or two particulars. 
4. Bolbonota inconspicua, sp.n. (Tab. II. figg. 5, 5 a.) 
Minima, brevis; capite pronotoque opacis, dense punctatis, hoc carind centrali supra viso integra, distincta, 
duabusque utrinque distinctis supra humeros ; dorso a latere viso equali vix sinuato, ante apicem obtusum
