ably less difference between its prothorax and elytra in height 

 (viewed from the side). Also in urticarum the eyes are less 

 widely separated from each other and the elytral interstices are 

 equal (or nearly so). The other species have their elytral inter- 

 stices equal.

ETHADOMORPHA (gen. nov. ErirhinaruTTi). 

 Corpus plus minusve squamosum ; rostrum (? utriusque sexus) 

 gracillimum valde elongatum (speciei typical quam pro- 

 thorax sat longius) arcuatum ; scrobes prasmedian^e, oblique 

 sub rostrum vergentes ; antenme minus elongatte, scapo 

 oculura haud plane attingenti, funiculo 7-articulato (articulis 

 basali sat robusto sat elongato, ceteris parvis inter se sub- 

 ?equalibus, apicalibus 3 gradatim paullo dilatatis) ; oculi 

 ovales grosse granulati ; prothorax transversus, antice 

 breviter subtubuliformis, lobis ocularibus nuUis, lateribus 

 leviter arcuatis, basi subrecta ; scutellum minimum ; elytra 

 quam prothorax sat latiora ; prosternum antice sat emargin- 

 atum, ante coxas minus elongatum, longitudinaliter nullo 

 modo concavo ; coxse antic?e fere (sed haud plane) contiguii?; 

 femora inermia ; tibiae anticse intus ad apicem breviter 

 mucronatse ; tarsi breves sat lati (articulis 3° bilobo, 4" 

 3""^ haud superanti) ; unguiculi minutissimi simplices ; seg- 

 menta ventralia basalia 2 inter se sat sequalia, 3"" 4° que 

 brevissimis. 

 The very small JErirhinid for which I propose this name can- 

 not be referred to any hitherto characterised genus. Its most 

 distinctive feature is in its tarsi which are short and broad, not 

 very unlike those of a Misophrice but with a minute claw joint 

 (in the emargination of the third joint) ending in two very 

 small simple divergent claws. In my tabulation of the Erirhinid 

 genera of Australia this one falls besides Omorophiiis (Tr. R.S., 

 S.A., 1894, p. 149), from which it is distinguished as follows : — 

 NN. Ocular lobes wanting. 



O. Apical joint of tarsi well developed .. .. Omorophius 



00. Apical joint of tarsi very minute and rob pass- 

 ing third joint ... ... . . ... Ethadomorpha 



It does not resemble Omorophius superficially, but has the 

 facies of Ethas which however has the fourth tarsal joint nor- 

 mally developed, the prothorax with ocular lobes, &c. Its tarsal 

 structure is nearest to that of Niphoholus (of known genera), but 

 that genus has considerably larger claws and very different ros- 

 tral and antennal characters. The apical mucro of the front 

 tibise is very small and little noticeable but I think 1 am right 

 as to its presence, — though in so minute an insect it is difficult 

 to be quite certain without breaking a specimen.
