CHELONARIUM. 689 
7. Chelonarium scabrosum, sp. n. 
Oblongo-ovale, piceum vel rufescens ; elytris pube variegata e setis albidis et fulvis composita, ante apicem 
fascia irregulari albida ; abdomine densissime scabroso-punctato ; antennis elongatis. 
Long. 53-7 millim. 
Hab. Mexico, Tuxtla (Sailé), Cerro de Plumas, Tapachula (Hoge); GUATEMALA, 
Zapote, San Isidro (Champion). 
Very similar to C. succinctum, but with the antenne much longer (almost 3 millim, 
long), and the abdominal punctuation remarkably dense, coarse, and rough, It is rather 
straighter at the sides, and therefore more oblong in form. There is a very evident 
setosity scattered all over the thorax, and a broad band of punctuation round the 
margins. The setosity of the elytra consists of a preapical irregular white band (very 
variable) and rather numerous white flecks elsewhere, and also of many tawny sete. 
When the pubescence is removed, the surface is seen to be dull and the sculpture much 
effaced. The metasternum is punctured all over. Nine specimens. 
8. Chelonarium gravidum, sp. n. 
Oblongo-ovale, nigricans, elytris copiose albido-setosis, ante apicem guttis irregularis quasi fasciam formantibus ; 
abdomine fortiter denseque punctato; antennis parvis. 
Long. 7 millim. 
Hab. Mexico, Acapulco, Tapachula (Hége). 
One of the largest and apparently darkest in colour of the white-clothed species of 
Chelonarium. Notwithstanding its large size, the antenn are scarcely 2 millim. long. 
Except for this, some of the specimens would be with difficulty separable from certain 
varieties of C. scabrosum. The punctuation of the ventral segments is extremely dense 
and confluent, so as to give rise to a very rough appearance, except along the middle of 
the basal two or three. Three specimens. 
I have referred to this species, as probably varieties, five specimens of smaller size, 
d-0# millim. long. Four of them are from Guatemala (Teleman and San J uan), the 
fifth from Mexico (Cerro de Plumas). 
9. Chelonarium prolixum, sp. n. 
Oblongo-ovale, elongatum, rufescens, sat nitidum, parce setosum et punctatum ; elytris guttis albidis, parum 
discretis, hinc inde sparsis ; corpore subtus dense fortiterque punctato, opaco. 
Long. 7, lat. 3 millim. 
Hab. Mexico, Cerro de Plumas (Hége). 
This is comparatively the most elongate, narrow, and parallel of the species. We 
have only one specimen and the antenne are imperfect; they appear to be slightly 
shorter than in C. scabrosum, but considerably longer than in C. gravidum. The 
definite sculpture of the elytra is more like that of the species of the C. mexicanum- 
group than that of the C. succinctum-group ; the surface is polished, sprinkled with
