burn are all distinctly larger and more coppery than the three males, one of them 

 has a slight purplish gloss on the elytra: the median line of their heads is usually 

 quite distinct, on the males it is absent or ill-defined. The eyes are large and 

 rather close together in the male (although not so close as in the preceding 

 species), the distance between them being about equal to the length of the basal 

 joint of the antennae, on the female they are almost twice as distant ; on both sexes 

 the inter-ocular space is sparsely punctate. The outlines and general appearance 

 are much as in D. congemtus, but the eyes of that species, sex for sex, are about 

 twice as far apart, and the prothorax has more distinct punctures. D. sohrinus. also 

 with very similar outlines, is non-metallic; 77. quadratipcnuis is somewhat wider, 

 with eyes more apart, prothoracic punctures much coarser and legs longer; from 

 D. crihkcps it difTers in having punctures of head very different, legs entirely 

 dark and eyes of female much closer; at first glance it is like metallic specimens 

 of D. pyf/idialis, but the eyes are very different and the prothorax is non-strigose, 

 the latter character also distinguishes it from D. sfrigicollis. 



DITROPIDUS QUADRATIPENNIS sp. nov. 



(J Bronzy ; basal half of antennae reddish, the club more or less deeply 

 infuscated, labrum obscurely diluted with red. Under-surface and legs with sparse 

 pubescence, head still more sparsely clothed. 



Head shagreened and with den.'-e ptmctures. more sharply defined on clypeus 

 than elsewhere. Eyes rather close together. Prothorax at base more than twice 

 the median length, sides strongly diminisjiing to apex: with fairly dense and 

 distinct punctures in middle, becoming coarse on sides. Elytra briefly sub- 

 oblong; with rows of fairly large ptmctures, on the sides set in deep striae; inter- 

 stices with very minute punctures. Legs moderatelv long, front ones slightly 

 long-er than hirid ones. Length (6 9^' ^ '6-3 mm. 



9 Differs in having more sharply defined punctures on head, eyes smaller 

 and about one-third more apart. ]irothorax shorter, elvtra slightly longer, and 

 slightly less narrowed posteriorly, legs shorter and thinner, the front ones no 

 Idiip--!- than the hind ones, and abdomen foveate.

A very compact species with eyes of the male almost as close together as on 

 the ]jreceding species, being but slightly more distant than the length of the 

 basal joint of antennae, but the two species differ in many other respects. .Some 

 specimens have a dark greenish gloss, others are somewhat ci^ppery. The hind 

 angles nf the prothorax are really slightly obtuse, hut from above thev seem
