NEW SPECIES OF COLEOPTEROUS INSECTS. 367 



particularly prominent in the female ; the meso- and metatihi(B 

 have also two teeth, but the upper tooth is frequently indis- 

 tinct ; in the males of Dia. dorsalis the protibice are unarmed, 

 in the females they have one tooth only. 



Colour of the male, {Dia. Ulysses). — Lamellw of the an- 

 ^ew^ce dusky ferruginous ; head black: prothoraa: iestsiceousy 

 with a large, amorphous, discoidal, black spot, which does 

 not reach any portion of the margin, except that immediately 

 adjoining the scutellum; in a single specimen I have also seen 

 it prolonged anteriorly to the head : scutellum black ; elytra 

 testaceous, with a black sutural stripe, w^hich is not dilated in 

 the middle ; the podex is testaceous, the abdomen black, with 

 a few lateral testaceous spots ; legs black. 



Colour of the female, [Dia. Penelope). — Antennae, head, 

 abdomen and legs as in the male : prothorax black, with the 

 anterior lateral margin femiginous ; elytra black, with a lon- 

 gitudinal, ferruginous, abbreviated line on each, between the 

 shoulder and scutellum: podex black, with two large and 

 somewhat quadrate ferruginous spots. 



Inhabits Kangaroo Island, Australasia. Mr. A. H. Davis 

 has presented to the cabinet of the Entomological Club, both 

 sexes of this insect. 



Genus. — Hispa, Linneus. 



Hispa higeneris. Nigra: antennariim articulus hasalis spinam acutam 

 ferens: prothorax spinis 5 acutis utrinque armatus: elytra profunde 

 puncta, margine dentato. (Corp. long. '2 unc. lat. '08 unc.) 



This singular insect combines the spinous prothorax of 

 the ijY^cdl HispcB of Europe with the smooth unarmed elytra 

 of the North American species : the colour is black ; the ba- 

 sal joint of the antenn<B bears a long, acute, porrected spine: 

 prothorax armed with five spines on each lateral margin; the 

 elytra are without spines, glabrous, and impressed with large, 

 deep, and almost confluent punctures, and the margin is arm- 

 ed with a series of short regular teeth.
