transversely suleate, the sulcation nearly straight. Elytra obso- 
letely depressed below the base, very minutely punctured. 
15. Aulacophora testacea, Fabr. Mant. Ins. i. 1787, p. 87. 
Oblonga, postiee paullo ampliata, convexa, fiava, nitida ; labro, pectore 
abdomiueque nigris; thorace vix pone medium transversim sulcato ; 
elytris infra basin leviter depressis, tenuissime punctatis. Long. 3 lin. 
Mas. Abdominis segmenti analis lobo intermedio transverso-quadrato, 
piano. 
Fcem. Abdominis segmento anali rotundato, integro. 
Sab. India {Fabr.) ; Assam ( Chennell : coll. Bali/). 
Labrum shining black ; antennae entirely flavous. Thorax 
nearly twice as broad as long ; sides nearly straight and slightly 
diverging from the base to beyond the middle ; disk transversely 
suleate immediately behind the middle, the sulcation straight. 
Elytra slightly hut distinctly depressed below the basilar space, 
very minutely punctured. Hinder femora in the male slightly 
stained on their outer surface with piceous. 
The entirely black abdomen, together with the entirely dif- 
ferent structure of the anal segment of the abdomen, will at 
once separate this species from A. foveicollis and A. abdominalis, 
with which insects it is usually confounded; it also differs from 
both in the depression below the basilar space of the elytra. 
16. Aulacophora flaviventris. Late ovata, postice ampliata, 
convexa, nigra, nitida, pectore piceo, abdomine antennisque (articulo 
basali exeepto) pallide flavis ; thorace lsevi, ad latera minute punctato, 
sulco transverso, fere recto, sat fortiter impresso ; elytris convexis, 
infra basin transversim excavatis, minute punctatis. Long. 4 lin. 
Mas. Abdominis segmento anali trilobato, lobo intermedio transverso- 
quadrato, piano, angulis anticis obtusis. 
Fcem. Abdominis segmento anali obtuso, leviter sinuato. 
Sab. Malay Peninsula, Penang, Tringano, Malacca. 
Antennae from the second to the tenth joint slender, filiform 
(the terminal joint broken off). Thorax nearly twice as broad 
as long ; sides nearly straight and slightly diverging from the 
base to beyond the middle, thence obliquely converging towards 
the apex ; upper surface smooth, very finely punctured on the sides; 
discoidal sulcation nearly straight, deeply impressed. Elytra much 
broader than the thorax, dilated posteriorly ; convex, transversely 
excavated below the basilar space, very minutely punctui’ed. 
Similar in form to A. lata, differing in the colour of the thorax 
and lower surface of the body, which is uniform in the three spe-
