TrYPOCOLASPIS SINUATA, 11. Sp. 



o' . Brassy or brassy-green : under-surface black, in part& 

 with a coppery-gloss, antennae and palpi somewhat flavous,. 

 the former with some of the apical joints infuscated at apex, 

 legs partly dark. 



Head with somewhat shorter antennae, but otherwise 

 much as on hiimjn'essa. Vroihonix much the same, except 

 that the two subfoveate impressions are entirely absent. Elytra 

 with rows (mostly regular) of rather large, deep punctures; 

 some of the interstices elevated above their fellows. Abdomen 

 with a small, circular median fovea. Middle tibiae wider at 

 apex than the others, hind pair rather strongly narrowed from 

 middle to base; basal joint of four front tarsi rather strongly 

 inflated. Length, l|-2 mm, 



9 . Differs in having the abdomen non-foveate, in having 

 thinner tibiae, and in the tarsi. 



Tiab. — Queensland: Cairns district (A. M. Lea). Type, 

 I. 3407. 



A beautiful little species, and apparently the smallest of 

 the subfamily in Australia. The elytra are without distinct 

 markings, but as some parts are more brassy than others they 

 do not appear to be quite uniformly coloured : the femora, 

 except near the base, are usually deeply infuscated, sometimes 

 almost black ; the hind tibiae are also sometimes infuscated : 

 one specimen has the whole of the upper-surface of a beautiful 

 violet colour. The striation of the elytra is not well impressed, 

 despite the regularity of the punctures, but posteriorly it 

 becomes deeper, the subsutural stria, however, is without 

 punctures on the apical slope : across the middle of each elytron 

 the third, sixth, and ninth interstices are slightly elevated 

 above their fellows, but elsewhere ^^"^^ their elevation is less 

 pronounced ; starting from each shoulder (but concealed from 

 above) there is a distinctly elevated interstice that commences 

 as the fourth (counting the margin as the first), rather 

 abruptly curves downwards to become the second, and con- 

 tinues till at the apex it joins the second and third subsutural 

 ones. 



Trypocolaspis ventralis, n. sp. 



c? . Brassy-green or brassy-blue ; elytra with metallic 

 spots, under-surface black, labrum and appendages more or 

 less reddish, but apical half of antennae infuscated. 



Head much as on biimpressa, except that the median 

 depression is more distinct and that the second joint of 

 antennae is shorter. Prothorax much the same, except that 



(97) Elsewhere their numbers differ owing to the brevity of 

 some of the rows of punctures.
