1. Celenopsis uropodoides, sp.n. (Tab. XVI. figg. 4-4 d, and Tab. XIX. figg. 
3, 3a, 6,2.) 
3 latet. 
. Corpus oblongo-ovatum, depressum, supra minime convexum, postice indistincte acuminatum. Scutum 
dorsuale limbo angustissimo, subnitidum, setulis brevibus in superficie et in margine suberectis munitum. 
Color badius. Sculptura microscopica e sulculis anastomosantibus confecta, qui areolas oblongas irregu- 
lares circumscribunt. In harum areolarum medio puncta seriatim disposita impressa sunt. Palpi et 
pedes marginem corporis superant. Superficies ventralis depressa, eandem structuram microscopicam 
sicut dorsualis preebens. Scutum ventrale magnum, postice acuminatum, marginem posticum corporis 
non attingens, orificium anale prope apicem ferens. Coxe utriusque lateris approximate. Inter coxas 
secundi atque tertii pedum paris orificium genitale (a clarissimo hujus generis auctore “ epigynium ” 
appellatum) in parte anteriore scuti ventralis situm est, magnum, subpentagonum, antice latum, angulo 
postico rotundatum. In epigynio distinguenda sunt :—(1) crista epigynica jugiformis, lateribus deflexis, 
transversa, antice arcuata ; (2) valva vulve utriusque lateris aleformis, interne atque antice rotundata, 
ad angulum internum anticum et prope marginis externi medium seta munita; (3) scutum parvum tri- 
gonum a margine postico epigynil inter valvas utriusque lateris paullo prodiens; (4) fulcra vulva clavi- 
formia, obliqua, arcuata. Ante epigynium scutum sternale hexagonum situm est, cuius margo anterior 
excavatus, lateralis in angulum rotundatum productus est. Ante angulum et prope marginem posticum 
in utroque latere setula inserta est. Scuta lateralia angusta, longa, prope marginem corporis posticum 
rima triangulari angusta, albida separata. Spiraculum parvum, prope coxas posticas externe situm. 
Pedes primi paris graciles, eorum tarsus unguibus carens, longus, setis numerosis ad apicem tactilibus, 
sicut articulus palporum extremus, munitus. Pedes ceteri inermes, crassiores, setulis muniti. Palpi 
inermes, sat longi. Epistoma trigonum, apice in mucronem acutum desinens. Mandibularum chel 
brachiis gracilibus, denticulatis ; dentes brachii mobiles ineequales ; ad apicem parvuli, conferti, infra inter 
se distantes, majores, pauci; in brachio fixo subsquales, apicem versus magis conferti ac breviores. 
Hypostoma in linguam antice rotunde truncatam desinens, ex qua processus duo longi setiformes nascuntur. 
Corniculi labiales basi lata in cornu extrorsus curvum acutum pellucidum desinunt. Brachium mobile 
membrana pellucida marginibus sinuatis longa imperfecte obtectum. Apparatus cibarius totus difficillime 
eruendus. 
Long. 0°75 millim. ; Jat. 0°50 millim. 
Hab. British Honpuras, R. Hondo (Blancaneauz). 
Male unknown. Body of the female ovate, depressed, moderately shining, bearing 
some short suberect hairs on all parts and showing a microscopic texture, consisting of 
a network of very fine irregular anastomosing furrows, which leave long irregular spaces 
between them, each space having a series of impressed points. The ventral plate is 
large and acute behind, and does not reach the end of the body. Anal orifice small, 
oblong, situated in the posterior angle of the ventral plate. ‘The space between the 
two rows of coxe rather narrow. ‘The genital orifice (called ‘ epigynium” by 
Mr. Berlese) is situated in the anterior portion of the ventral plate ; it is large, some- 
what pentagonal in shape, broad at its anterior margin, rounded behind. ‘The sternal 
plate is hexagonal, excavate at its anterior margin, the lateral margin forming a rounded 
angle. ‘The lateral pieces are long and narrow, separated from the ventral piece by a
