Oriental Scolytide of economic importance. 429 
rotundatis, dorso medio transverse elevato, postice in medio dense 
subtiliter cribrose punctato et breviter hirto, linea media longitudinali 
subelevata ; elytris prothorace longioribus, perindistincte lneato- 
punctatis, interstitiis irregulariter punctatis, apice oblique truncato- 
retuso, margine per totum acuto, subcirculari, fundo utrinque ad 
suturam gradatim elevato et medio subimpresso, haud omnino opaco, 
subirregulariter lineato-punctato, interstitiis haud perspicue punctatis, 
Long. 3°3 millim. 
Fem. Closely allied to X. amputatus, Blandf. (Trans, Ent. Soc., 
Lond., 1894, p. 575). Rather larger and more robust. Front 
(concealed in the type of X. amputatus) convex, subopaque, rather 
closely and finely punctate with a short shining elevated longitudinal 
line above the middle of the shining blackish epistoma ; eyes rather 
deeply emarginate. Sides of the prothorax nearly straight behind the 
middle, its surface as in X. amputatus but with the basal patch of 
piliferous punctures more conspicuous. Elytra much darker apically, 
nearly black, the fundus of the apical retuse surface distinctly less 
opaque (in X. amputatus it has not the slightest gloss), not concave 
on each side but gradually raised towards the suture, with a some- 
what irregular surface, due to a slight impression on each side, the 
rows of punctures somewhat wavy, the punctures rather large, shallow 
subnitid impressions (in X. amputatus the rows are perfectly straight 
and the punctures are small and not shining), interstitial punctures 
not perceptible (evident in X. amputatus). 
Hab. CrE8yYLon (£. £. Green). 
This species, though really distinct from 1. amputatus 
upon comparison, is so far alike that I was unable to 
separate it by means of my former description, and was 
obliged to have recourse to my type of the latter species, 
which Mr. Lewis kindly lent me for the purpose of com- 
parison. 
AXyleborus discolor, sp. n. 
Q. Forma X. brevi, Eichh., proxima, sed multo minor, elytris 
brevioribus, colore distincta. Curta, cylindrica, laete testacea ; 
elytris nigris abrupte truncatis, truncatura circulari, breviter fulvo- 
pilosa. Long. 1.8 millim. 
Fem. Allied to X. brevis, Eichh., but much smaller. Short, 
cylindrical, bright testaceous, with the elytra black. Head dull, 
the front rather finely punctate, with a fine raised median longi- 
tudinal line ; mouth infuscate ; eyes deeply emarginate. Prothorax 
as long as broad, the sides nearly straight behind, gradually rounded 
to the apex in an ellipse ; discal elevation post-median, indistinct ;
