surface is market! with a number of shallow scattered punctures, 

 having a brassy greenish tinge. The white spots are sometimes more 

 and sometimes less developed ; the anterior discoidal spot is some- 

 times linear, and clavate at its posterior end ; it is the hinder portion 

 of what in other species is the humeral lunule ; the lateral line is 

 sometimes absent ; the apical virgula narrows off, and does not reach 

 the sutural angle.

 strigosis, aureo-cupreis, late cyaneo marginatis ; elytris obscure 

 cupreis, sutura viridi, lateribus cyaneo limbatis, cequaliter di- 

 stincte punctatis, lunula humerali brevi, macula parva trans- 

 versa laterali apud medium alterisque duabus apicalibus albis ; 

 capite inter oculos valde depresso, utrinque multistriato ; labro 

 utroque sexu testaceo, medio dente valido, margine anterior e 

 recto, angulis lateralibus distinctis ; antennis gracilibus, elon- 

 gatis ; elytris dente suturali acuto ; subtus pedibusque elon-

Closely allied to C. craspedota, Schaum, from Celebes, differing 

 in being rather more elongated, with the elytra opake instead of 

 shining, and in having a humeral lunule and a spot at the sutural 

 apex of the elytra. The thorax is elongate, narrow, and almost per- 

 fectly cylindrical. The head is strongly depressed between the eyes ; 

 the labrum has in both sexes a longish central tooth, and its front 

 edge forms a straight line from the tooth to the lateral angles, which 

 are distinct. The antennae are long and slender ; the palpi pale 

 yellow, with the terminal joints brassy green. The head and thorax 

 are of a rather bright coppery hue with a golden tinge, and with 

 their sides broadly margined with greenish hlue. The elytra are dull 

 copper, and uniformly covered with largish and distant punctures ; 

 the suture is shining green, and the lateral borders dark greenish 

 hlue ; the humeral lunule is short and slender, the marginal spot in 

 the middle is broader than long, the subapical marginal spot is small 

 and reniform. 



COLLYRIS EORMOSANA. 



Cyanea, nitida, elytris viridi-cceruleis, capite et thorace late vio- 

 laceis, labro chalybeo ; antennis subelongatis, a.rticulis basali- 

 bus cyaneis, 3°-/ m rufo-piceis (ccetera desunt); capite pone ocu- 

 los subquadrato, angulis rotundatis, front e bisulcata, intersfifio 

 longitudinaliter elevato; thorace capite paulo longiore, prope 

 apicem et basin modice strangulato, parte media rotundata ; 

 elytris cequaliter usque ad apices punctatis, apice ( $ ) jlexuoso- 

 truncatis, angulo suturali product o ; femoribus anticis et inter- 

 mediis rufis, geniculis cum tibiis et tarsis jriceis ; pedibus pos- 

 ticis nigris, femoribus basi rufis, trochanteribus omnibus rufis.
