TOMASPIS. 189 
our collection is almost entirely of a fuscous colour, and has the pronotum rather more 
distinctly punctured ; it possibly belongs to a distinct species. 
I have been enabled to identify Stal’s insect through the kindness of Dr. Aurivillius, 
who lent me a typical specimen. 
We figure two examples from Omilteme, one of which (fig. 28) is a variety. 
34. Tomaspis lineata. (Tab..XI. figg. 29, 29a; 30, 30a, var. similis.) 
Sphenorhina lineata, Walk. List of Homopt. Ins. iii. p. 691 (1851) *. 
Sphenorhina parallela, Walk. loc. cit. p. 694°. 
Sphenorhina bivitta, Walk. loc. cit., Suppl. p. 181 (1858) *. 
Sphenorhina cruciata, Walk. loc. cit., Suppl. p. 183 *. 
Sphenorhina similis, Walk. loc. cit., Suppl. p. 182’. 
Tomaspis vittatipennis, Stal, Stett. ent. Zeit. xxv. p. 64 (1864) °. 
Tomaspis ornatipennis, Stal, loc. cit. p. 647. 
Hab. Mexico (Sallé?45; Mus. Holm.8* and coll. Signoret®), Pinos Altos in Chihuahua 
(Buchan-Hepburn), Amula and Chilpancingo in Guerrero, Teapa in Tabasco (H. #. 
Smith), Atoyac in Vera Cruz (Schumann), Valladolid in Yucatan (Gaumer); Honpuras 
(Dyson ', in Mus. Brit.) ; Nicaragua, Chontales (Janson).—Sourn AMERICA ?. 
This is a very variable insect, the ground-colour varying from bright scarlet to a 
dirty testaceous, and the smallest specimens being about half the size of the largest. 
It is not, therefore, to be wondered at that a considerable number of species have been 
described which must be sunk as synonyms; a glance over our series and the specimens 
in the British Museum will show how they lead one into the other. 
There can be little doubt that all the above-mentioned so-called species might be 
referred to Sphenorhina lineolata, Amyot and Serville [Hist. Nat. des Ins., Hémipt. 
p. 563, t. 10. f. 7 (1843)]; but, as their description is very meagre and the locality is 
given as “ Amérique méridionale?” I prefer to adopt the above synonymy. 
We figure two specimens—one, of the ordinary form, from Chilpancingo, and a 
variety (=S. similis, Walk.) from Teapa. 
35. Tomaspis nuptialis. (Tab. XI. figg. 31, 31a.) 
Tomaspis nuptialis, Stal, Stett. ent. Zeit. xxv. p. 64 (1864) 
Hab. Mexico (coll. Signoret 1, in Mus. Vind. Cas.). 
I am inclined to regard this as an extreme variety of the preceding species; but it 
has the metopidium a little less produced, and is very strikingly coloured. It is not 
represented in our collection. 
A specimen of Stl’s in the Vienna Museum collection is figured.
