HYPHINOE. 17 
7. Hyphinoé purulensis, sp. n. (Tab. VI. figg. 4, 4a, 6, 2; 5, 5a, 4, 3.) 
@. Violaceo-brunnea, pronoto elongato, dorso fere recto, fortiter sat remote punctato, margine anguste flava 
ab humeris usque ad apicem nigrum extensd, puncto utrinque sat magno laterali, et altero parvo pone 
cornua, nigro, cornibus modicis, subacutis, apicibus nigris; tegminibus violaceo-brunneis, nitidis, fortius 
punctatis ; pedibus ferrugineis. 
3. Multo minor, metopidio supra viso ante cornua obtuso semicirculariter extenso, laterum maculis majoribus, 
et colore dilutiore. 
Female elongate, shining, olivaceous or violaceous-brown ; the pronotum elongate, almost straight along the 
back, and gradually narrowed into a slender apical process, which is very slightly curved over the tegmina; 
the apex and tips of the horns are black, and there is a black spot on each side and another behind the 
horns; the lateral margins from the shoulders to the apex are narrowly yellow, the colour being distinctly 
marked; the horns are robust, subacute, and directed upwards, with the disc between them broad and 
slightly hollowed ; tegmina dark violaceous-brown, strongly punctured, especially towards the base; legs 
ferruginous. 
Long. 17, cum tegm. 18 millim.; lat. int. corn. Y millim. 
Male much smaller, with the frontal portion of the pronotum semicircularly extended beyond the horns, which 
are blunt; the yellow margins of the pronotum are broader and the lateral black patches much larger ; 
the black patches behind the shoulders are more distinct, and they show a tendency in one or two specimens 
to become linear and to join the black tips of the horns ; in neither sex is there a black subhumeral band. 
Long. 13, cum tegm. 14 millim. ; lat. int. corn. 7 millim. 
Hab. Guatemata, Purula and Sabo in Vera Paz (Champion). 
Besides the specimens from these localities, there is a testaceous example from 
Senahu, Vera Paz, with a minute lateral black spot on each side of the pronotum, and 
no spot behind the shoulders; it has the horns, too, shaped more as in H. cornuta, but 
there is no dark subhumeral band. ‘The horns in several of these allied forms appear 
to vary occasionally, asin Ceresa, and it is possible that, when more specimens are forth- 
coming, some of the described species of Hyphinoé may prove to be not really distinct. 
In our collection there is also a small cornute male, from Cerro Zunil, Guatemala 
(Champion), which closely resembles H. purwlensis, except that it is of a lighter colour 
than the ordinary form, and has no black spot behind the shoulders; at first sight it 
looks like a distinct species, but it agrees almost exactly in size and shape with a 
dimorphic cornute male of H. asphaltina which has been before referred to. I have, 
therefore, though with considerable hesitation, included it as a dimorphic form of the 
male of H. purulensis. 
8. Hyphinoé vulpecula, sp.n. (Tab. VI. figg. 6, 6 a, b.) 
Elongata, brunnea, nitida, cornibus apicem versus et apice ipso pronoti nigris, tegminibus brunneis; pronoto 
elongato, leviter subrugoso, sat fortiter remotins punctato; cornibus longioribus, leviter curvatis ad 
apicem obtuse rotundatis ; dorso paullo post medium sensim declivi; processu longo usque ad apicem 
tegminum extenso ; pedibus testaceis. 
Elongate, very shining, of a unicolorous brown colour, with the dorsal ridge almost straight, very slightly 
sinuate behind the middle, and prolonged into a narrow process behind, which almost reaches the apex of 
the tegmina; tegmina brown or brownish-testaceous, the basal half strongly punctured; legs testaceous. 
Underside variable, but darker than the rest of the body. 
Long. 16-17 millim.; lat. int. corn. 10 millim.
