COLEOPTERA 



221 



This species has a good deal the shape of the European Platyni. The margins 

 of the thorax and elytra are dilute in colour to a variable extent. The var. fuscipes is 

 represented by only four specimens : three of them have the elytra more deeply striate, 

 especially at the tip, but the fourth agrees in this respect with the pale-legged form.

(14) Atelothrus platynoides, sp. nov. 



Subdepressus, nigro-piceus, antennis, palpis pedibusque fusco-testaceis ; thorace 

 subplanato, basin versus fortiter angustato ; elytris posterius latioribus, profunde 

 striatis, ad apicem fortiter sinuatis, apicibus parum productis, fere singulatim rotundatis. 

 Long. 6J — 7^ mm. 



WdLV. JIavipes, var. nov. Pedibus flavis. 



This is extremely similar to A. depresses var. fuscipes, but is slightly broader, has 

 the elytra a little more sinuate behind, and the fourth joint of the hind tarsus quite 

 distinctly bilobed. 



I originally described this species from a single specimen, and quite recently have 

 received three others from Mr Perkins that confirm its distinctness. The tarsal structure 

 approaches that of ^. dyscoleus and of Metromenus pabiiac. There is no difference in 

 form in the tarsi of the two sexes. Of the W3.r. flavipes only a single specimen has been 

 found. I see no distinction in it except the colour of the legs, and in this group of 

 Atelotliriis this character does not appear to me to indicate specific distinctness. This 

 variety is very near A. gracilis, though the form in platytioides is considerably narrower, 

 and the tarsi are distinctly more slender.

(15) Atelothrits transiens, sp. nov. 



Piceo testaceoque variegatus, antennis pedibusque flavis ; prothorace inaequali, basin 

 versus angustato ; elytris sat nitidis, piceis, flavo-marginatis, interstitiis elevatis, angulatis, 

 alternis saepius altioribus. Long. 6 — 7 mm. 



In this extraordinary species the setae on the thorax are very rarely present, though 

 their pits are always evident on the inner face of the side-margin quite near to, if not on, 

 the summit. It differs from all the other species of the genus in its sculpture, and in 

 this respect resembles the aberrant forms of McsothHsciis and Meh'omenus from the 

 same island — Kauai. The head is black. Thorax a good deal narrowed behind, 

 yellowish, more or less infuscate, with the margins pale, the surface always more or less 

 crumpled, sometimes strongly so. The elytra are rendered somewhat dull by an
