290 HEMIPTERA-HETEROPTERA. 
1. Acholla ampliata, (Tab. XVIII. figg. 1, la, 2.) 
Acholla ampliata, Stal, Enum. Hemipt. ii. p. 72 (9) *. 
Hab. Mexico, Oaxaca (Mus. Holm. 1). 
This species is closely allied to the North-American A. multispinosa (De G.), but 
differs from that insect in having the head shorter, with the post-ocular portion more 
tumid anteriorly, and the pronotum broader, with the tubercles on the anterior lobe 
more raised. ‘The type is figured. 
2. Acholla tabida, (Tab. XVIII. figg. 2,2a,3; 38, 2.) 
Ascra tabida, Stal, Stett. ent. Zeit. 1862, p. 446 (¢)*. 
Acholla tabida, Enum. Hemipt. ii. p. 72°; Uhler, Bull. U.S. Geol. & Geogr. Surv. i. p. 326°. 
Hab, Norta America, California ?—Mexico!23, Orizaba (Bilimek, in Mus. Vind. 
Ces.; H. H. Smith; Godman); Guatemata, Capetillo (Champion). 
We possess three specimens of this species, and I have seen four others belonging 
to the Vienna Museum, including the type. A. tabida also is very like A. multispinosa 
(De G.) (an example of which has been sent me by Prof. Uhler); but it has a less 
elongate head, and the spiniform elevations on the head and anterior lobe of the 
pronotum are not nearly so prominent. The males (unknown to Stal) have a narrow 
abdomen. We figure a pair from Orizaba. 
SINDALA. 
Sindala, Stal, Stett. ent. Zeit. 1861, p. 188; Hemipt. Afr. iii. p. 47; Enum. Hemipt. ii. pp. 67, 71. 
This genus is closely allied to Sinea, but differs from it in the unarmed anterior tibie. 
1. Sindala brevis, n. sp. (Tab. XVIII. figg. 4, 4a, 2.) 
Q. Very like S. granuligera, Stal, but much less elongate; the antenna shorter; the head shorter than the 
pronotum, the latter not longer than broad and with acute, outwardly directed, lateral angles; the head 
with shorter spines above and more numerous short spines beneath; the abdomen more dilated beyond 
the middle, with the outer apical angles of the fourth and fifth segments somewhat rounded, those of 
the fourth being prominent ; the spines on the lower side of the anterior femora very much shorter, there 
being four only in the series at all prominent; the legs much shorter and stouter. 
Length 9,;, breadth 33 millim. 
Hab. Panama, Bugaba (Champion). 
One specimen. This insect is so like 8. granuligera, Stal, from Colombia and 
Brazil (the type of the female * of which is before me), that the comparative differences 
mentioned above are sufficient for the purposes of identification. 
- * This specimen has the abdomen abnormally formed, the outer apical angle of the fourth connexival 
segment being produced into a stout dentiform process on the right side only.
