THIONIA. 123 
2. Thionia brevior, sp.n. (Tab. XII. figg. 17, 17 a.) 
Brevis, testacea, fusco obscure irrorata; vertice brevi, fronte fere subquadrata, nigrescente; oculis permagnis; 
pronoto antice leviter rotundato, postice fere recto; tegminibus sat nitidis, venis crassis, postice plus 
minusye reticulatis, basim versus leviter contractis, pone medium latioribus; tibiis posticis robustis, 
spinis duabus magnis. . 
A short and broad species, testaceous, with obscure, closely-set, fuscous markings; head (viewed from above) 
very short, together with the large eyes as broad as the base of the tegmina; frons almost subquadrate, 
dark, with minute lighter markings at the sides; pronotum bow-shaped; tegmina (viewed from above) 
broadest at the middle and then distinctly, though gently, contracted and narrowed to the base, 
the margins strongly rounded posteriorly ; legs testaceous, with fuscous markings, posterior tibise with 
two stout spines before the apex. 
Long. cum tegm. 5-6 millim.; lat. ad hum. 34-4 millim. 
Hab. Mexico, Atoyac in Vera Cruz (Schumann); Panama, Bugaba, Volcan de 
Chiriqui (Champion). 
This species may be easily distinguished from the preceding by the shorter and 
comparatively wider vertex, the shorter form, and the contraction of the tegmina just 
before the middle. A specimen from Bugaba is figured. 
8. Thionia maculipes. 
Thionia maculipes, Stal, Stett. ent. Zeit. xxv. p. 51’. 
Hab. Mexico (Mus. Vind. Ces.'). 
A small, obscure insect, of a pale testaceous colour, the tegmina semitransparent, 
and the femora with a black spot at the apex. 
4. Thionia scutellata, sp.n. (Tab. XII. figg. 18, 18 a.) 
Issus scutellatus, Sign. in litt. 
Brevis, testaceus, capite sat magno, vertice subquadrato, fronte haud lata, lateribus apicem versus sensim 
angustatis; pronoto antice late angulato, ad medium biimpresso ; tegminibus brunneo-testaceis, vitta 
irregulari fused pone humeros, ante medium rotundato-angulatis, apicibus oblique rotundato-truncatis ; 
corpore subtus pedibusque plus minusve testaceis. 
Mas segmento ultimo ventrali ad medium producto, penultimo et precedente ad medium callosis, illo 
semicirculariter producto, processu anali longo et robusto apicem versus angustiori. 
Short, testaceous, with the head somewhat large, the vertex subquadrate ; the forehead rather long and narrow, 
gently rounded, very gradually narrowed towards the vertex, which extends slightly before the eyes ; 
pronotum angled in front, with the hind margin before the scutellum almost straight, the dise with two 
distinct impressions ; scutellum with dark markings; tegmina testaceous, with one or two irregular 
fuscous bands, rather broad, distinctly, though roundly, angled behind the shoulders, the humeral callosity 
evident, the apex obliquely rotundate-truncate ; underside and legs testaceous, with fuscous markings. 
In the male the last ventral segment is distinctly produced in the middle, and the penultimate segment is 
produced semicircularly, both furnished with greyish callosities edged behind with dark colour. 
Long. cum tegm. 6 millim.; lat. ad hum. 24-3 millim. 
Hab. Mexico (Mus. Vind. Ces.), Atoyac in Vera Cruz (H. H. Smith). 
Several specimens. There is also in our collection an example from the Volcan de 
Atitlan, Guatemala, which appears to belong to the same species.
