The insects dealt with in this part are mostly fnngus-freqnenting species. It will 

 l)e noticed that Diphijllus and DipJocoelus are referred to the Erotylidae, instead 

 of to the Mycetophagidae, the former family being now ijonsidered l)y many 

 anthors to be their trne location. 



COLASPOIDES CUPREOVIRIDIS sp. nov. 



$ Bright metallic coppery-green, nnder-surface less conspicnously metallic 

 and tip of abdomen reddish; labrnm, legs, antennae and palpi reddish, tips of 

 antennae infuseated. . 



Head with fairly dense bnt irregular punctures between eyes, becoming 

 smaller and sparser about base, and more crowded on dypeus; median line well- 

 defined. Antennae rather long and tliin, third joint no shorter than fourth. 

 Prothorax about tAvice as wide as the median length, sides evenly rounded, all 

 angles slightly armed; middle with rather small and not very dense punctures, 

 l)ecoming larger but not much denser on sides. Scutellum impunctate. Elytra 

 rather short; with fairly large punctures, subgeminately arranged in parts, 

 posteriori}- confined to distinct striae, larger than elsewhere and transversely 

 confluent behind shoulders. Apical segment of abdomen feeldy transversely 

 impressed, but in middle shallowly foveate. I^egs rather short and stout ; front 

 femora acutely dentate ; basal joint of front and middle tarsi dilated, of hind pair 

 as long as the two following combined ; hind tiliiae longer than the others, gently 

 emarginate on lower-surface beyond middle, and then dilated to apex. Length, 

 5-5-25 mm.

A bright-green species like C. hicarinata, elegantuhi, and foveivent7'is, but 

 readily distinguished from these by the abdomen and hind tibiae: the latter are 

 distinctly dilated near apex, but less suddenly and strongly than in foveiventris, 

 and the abdominal fovea is shallower, with its outline less circulai-,
