ACANALONIA. | 49 
Il. Head truncate or obtusely and slightly produced. 
9. Acanalonia virescens. (Tab. VII. figg. 7, 7a.) 
Acanonia virescens, Stal, Stett. ent. Zeit. xxv. p. 56°. 
Hab. Mexico (Mus. Holm.!; Bilimek, in Mus. Vind. Cos.; Sallé), Orizaba 
(Ff. D. Godman & H. H. Smith), Temax and Valladolid in Yucatan (Gaumer) ; 
GuaTEeMALA, Lanquin, Cahabon, and San Gerénimo in Vera Paz, El Reposo (Cham- 
pion); Panama, Caldera, Bugaba, Volcan de Chiriqui (Champion). 
I have felt great difficulty with regard to this insect, and it is possible that there may 
be two species in our series ; in fact, I had described one as distinct from A. virescens, 
but the occurrence of intermediate examples, in one instance from the same locality, 
led me on further examination to withdraw it. The specimen in question has the 
tegmina more oblong and less rounded on the costal margin, but otherwise does not 
appear to differ in any material point. 
An example from Bugaba is figured. 
10. Acanalonia delicatula, sp. n. (Tab. VII. fig. 8.) 
Parva, pallide virescens, hyalina; capite perbrevi, vertice subtruncato; pronoto perangusto; scutello longo, 
leviter tricarinato; tegminibus sat angustis, subparallelis, virescenti-hyalinis, marginibus extremis 
peranguste brunneis. 
A very small, pale green insect, with transparent tegmina; head very short, plainly ridged between the vertex 
and the frons, subtruncate in front; scutellum long, with traces of three carine; tegmina narrow, 
subparallel, of a transparent pale greenish colour, with the extreme edges brownish ; wings large, milky- 
white. 
Long. 63 millim.; lat. vix 2 millim. 
Hab. Panama, Bugaba (Champion). 
11. Acanalonia concinnula, sp.n. (Tab. VII. figg. 9, 9a.) 
Parva, dilute virescens; capite perbrevi, haud producto; pronoto brevissimo ; scutello lato, simplici; tegmi- 
nibus amplis, latis, rotundatis, margine externo corii testaceo-brunneo ; alis parvis, lacteis. 
A very small, light green species, with the head very short, not much longer than the pronotum, truncate and 
not produced, the eyes prominent, large ; scutellum broad, smooth ; tegmina large, strongly rounded, rather 
finely reticulate, with the outer edge of the corium brownish-testaceous ; wings small in proportion to the 
tegmina ; legs fuscous, but probably more or less green in life. 
Long. 5 millim.; lat. ad hum. 1-14 millim. 
Hab. Mexico (Bilimek, in Mus. Vind. Ces.), Jalisco (Schumann), Chilpancingo in 
Guerrero 4600 feet (H. H. Smith). 
One of our specimens from Chilpancingo appears to have two dark markings on the 
outer margin of each tegmen, but they are evidently nothing but stains when closely 
examined. 
An example from Chilpancingo is figured.
