144 HEMIPTERA-HOMOPTERA. 
‘appear to be confined to the New World. They differ very considerably in facies, but 
it is hard to draw a line between them in the present state of our knowledge; I have, 
therefore, thought it best to include Heliria, which was separated off by Stal entirely 
on the form of the dorsal protuberance. | 
1. Telamona excelsa, (Tab. IX. figg. 4, 4a.) 
Thelia eacelsa, Fairm. Ann, Soc. Ent. Fr. sér. 2, iv. p. 310’. 
Hab. Mexico (coll. Signoret ! & Sichel, in Mus. Vind. Ces.). 
This is a large and very remarkable insect, the pronotum being very strongly, broadly, 
and evenly elevated for the greater part of its extent. 
2. Telamona mexicana. (Tab. IX. figg. 5, 5 a-c.) 
Telamona mexicana, Stal, Ofv. Kongl. Vet.-Ak. Férh. 1869, p. 249°. 
Hab. Mexico (Mus. Holm.?). 
This species, though considerably smaller than the preceding, and in many points 
different, is yet certainly allied to it. We are indebted to Dr. Aurivillius for the 
opportunity of figuring the typical specimen in the Stockholm Museum. 
3. Telamona cristata. (Tab. IX. figg. 6, 62.) 
Thelia cristata, Fairm, Ann. Soc. Ent. Fr. sér. 2, iv. p. 311°. 
Heliria cristata, Stal, Ofv. Kongl. Vet.-Ak. Férh. 1867, p. 5562. 
Hab. Mexico (coll. Signoret ', in Mus. Vind. Ces.). 
This is a very curious-looking insect, very different from the two preceding, and 
closely related to the species that follow. 
4. Telamona sinuata, sp.n. (Tab. IX. figg. 7, 7a, 3.) 
Preecedenti affinis, sed paullo major, humeris multo magis prominentibus, late auritis, protuberantidque dorsali 
antice magis quam postice elevaté ad medium sinuata, angulo antico late rotundato, postico acuto; colore 
griseo vel albido-griseo, fusco-variegato ; tegminibus hyalinis, apicem versus fuscatis, venis fuscis partim 
brunneis. 
Very like the preceding, but rather larger, and easily known by the much more broadly prcminent shoulders, 
and by the shape of the dorsal protuberance, which is more raised in front (where it forms a second 
rounded protuberance) than behind, and is sinuate in the middle, the hinder angle being acute; the 
colour is griseous, variegated with fuscous. 
Long. cum tegm. 11 millim.; lat. int. hum. 7 millim. 
Hab. Mexico, Amula 6000 feet and Xucumanatlan 7000 feet, both in Guerrero 
(H. H. Smith). 
A male from Amula and a female from Xucumanatlan. This species appears to be 
closely allied to 7. ¢ristis, Fitch, as well as to T. salvini, Dist., and 7. spreta, Goding. 
The male is figured.
