drawn from the Chilian insect. The Mexican insect remains unknown to me, and also 
to M. Fauvel; but the latter authority considers the genus a valid one, so far, at any 
rate, as its Chilian exponents are concerned. 
1. Leptoglossa puberula. 
Homalota puberula, Solsky, Bull. Mose. xiii. p. 259°. 
Hab. Mexico (Boucard'). 
Described from a unique individual, whose habitat is not known more precisely. 
LEPTONIA. 
Coxe intermedi sat late distantes ; processus mesosternalis inter eas parum productus, apice lato, rotundato- 
truncato. Gen obsoletissime marginate. Tarsi posteriores graciles, elongati, tibiis breviores, arti- 
culis quatuor basalibus subequalibus, articulo primo quam secundus vix longiore, articulo quinto quam 
quartus duplo longiore. 
I have established this genus for an insect which tends to connect Myrmedonia, 
Thamiarea, and Homalota; it differs from the former genus by the structure of the 
hind tarsi, and from Thamiarwa and Homalota by the more widely separated middle 
coxee, with short, broad mesosternal lobe. Calodera syntheta, Sharp, should belong to 
it: when describing that insect (Trans. Ent. Soc. Lond. 1876, p. 59) I stated that the 
anterior tarsi were five-jointed; and such is apparently the case; but I have mounted 
an anterior leg of Leptonia picta in Canada balsam, and it is then evident that the 
appearance of division of the terminal joint is illusory, and the front tarsi are certainly 
only four-jointed, the terminal joint being very long, considerably longer, in fact, than 
the other three together, while the middle and hind feet possess really five joints. 
1. Leptonia picta. (Tab. V. fig. 15.) 
Gracilis, antennis laxe articulatis, articulo ultimo perelongato ; capite thoraceque nigro-submetallescentibus, hoc 
sat fortiter punctato, transversim subquadrato; elytris fuscis basi testaceis; abdomine apicem versus 
subacuminato, nigro-testaceo variegato, parum punctato, nitidulo. 
Long. 3-43 millim. 
Hab. Mexico, Cordova (Sallé); British Honpuras, Belize (Blancaneaux) ; Guats- 
MALA, Cerro Zunil 4000 to 5000 feet and San Gerdnimo (Champion); Nicaragua, 
Chontales (Janson); Panama, Bugaba and Volcan de Chiriqui 3000 to 4000 feet

Antenne elongate, rather slender, the four basal joints yellow, the others darker; 
third joint elongate and slender, rather longer than second; fourth joint twice as long 
as broad, tenth about long as broad; terminal joint remarkably elongate, as long as the 
three preceding together. Head a good deal narrower than the’ thorax, rounded 
behind the large eyes, only very obscurely punctate. ‘Thorax not quite so long as 
broad, a little narrowed behind and sinuate near the hind angles, which are distinct
