GYPONA. 297 
2. Gypona bimaculata. (Tab. XX. fige. 4, 4a, b, 9.) 
Gypona bimaculata, Spingb. Bihang till K. Sy. Vet.-Ak. Handl. v. 3, p. 237. 
Hab. Mexico} (Bilimek, in Mus. Vind. Cws.), Chilpancingo in Guerrero, 4600 feet 
(HI. H. Smith). 
This insect is closely allied to G. germari, but may be distinguished by the two 
minute but distinct black spots on the pronotum, and by the last ventral segment of 
the female being a little longer than the penultimate, feebly sinuate at the tip, and with 
a very slight subemarginate lobe in the centre. In the male the last ventral segment 
is about as long as the penultimate, and subtruncate at the apex. The specimen 
figured is from Chilpancingo. 
3. Gypona unicolor. 
Gypona unicolor, Stal, Stett. ent. Zeit. xxv. p. 84’. 
Hab. Nortu America, Colorado (Mus. Vind. Ces.).—MeExico!, Teapa in Tabasco 
(Hl. H. Smith); Guatemata, Cerro Zunil (Champion). 
This appears to be a very obscure species. I have seen two specimens belonging to 
the Vienna Museum labelled “G. wnicolor”: one, from Colorado, presented by 
Spangberg; the other, which apparently ought to be referred to G. germari, from 
Mexico, and presented by Signoret. I have doubtfully identified two insects in our 
collection as small examples of G. unicolor, which appears chiefly to differ from 
G. germari in the subtruncate or only slightly sinuate last segment of the abdomen in 
the female, and in the absence of pale bands on the head and pronotum; but these 
latter are often untraceable in dead and faded specimens of G. germari. 
4, Gypona delicata, sp. n. (Tab. XX. figg. 5, 5a, 4, 2.) 
Parva, hyalina, dilute flavescens, immaculata ; capite sat magno et producto, antice rotundato, pronoto haud 
angustiori, oculis leviter prominulis, ocellis approximatis ; pronoto brevi, capite vix longiori, levissime 
transversim rugoso; scutello #quilaterali; tegminibus hyalinis, venis corii crassatis (reticulatis) ; alis 
hyalinis ; corpore subtus et pedibus dilute testaceis. 
Mas ignotus. Femina segmento ultimo ventrali plus minusve late emarginato. 
A small, transparent, pale testaceous species, with the head rather large, as broad at the base as the pronotum 
and of about the same length; eyes only slightly prominent; ocelli approximate; pronotum short, very 
finely rugose transversely ; scutellum equilateral; tegmina transparent, with the veins on the corium 
strongly raised and reticulate ; wings transparent ; legs and underside pale testaceous. 
Male unknown. Female with the last segment of the abdomen more or less broadly emarginate. 
Long. 7 millim.; lat. ad hum. 3 millim. 
Hab. Mexico, Chilpancingo, Xucumanatlan, and Amula in Guerrero, 4600 to 7000 feet 
(H. H. Smith). 
A very distinct species, at first sight closely resembling a faded example of 
G. germari. The specimen figured is from Amula,
