3. DiSTYPSIDERA PaSCOEI. 



Cyaneous-black, the head and thorax a little coppery. Head as 

 in the last-described species, but rather more hollowed between the 

 eyes, without the yellow spot below the insertion of the antenna?, 

 the striolation generally finer, and the outer side of the 

 mandibles white nearly to the tip. The thorax is shaped like that 

 of D. Jlavipes, but much more smoothly sculptured. The elytra 

 are transversely rugose and thinly punctured. A round spot on 

 the base near the suture, larger humeral spots with a lunulate 

 extension towards the middle of the disk, and two spots about one 

 third from the apex, narrowly joined together, one touching the 

 lateral margin, the other not reaching the suture yellow. The 

 apex of the suture is slightly pointed. The thighs are reddish 

 yellow with a brownish tint on the outside and towards the apex, 

 the tibife and tarsi are all somewhat brownish. 



Length, 7^ lines. 



Hab. — Cairns. 



This s])ecies seems to resemble Mr. Pascoe's species, D. Grutii, 

 from Lizard Island, but Mr. Pascoe's description differs in some 

 respects so much from the present insect, that they cannot possibly 

 be the same. I have named it after that distinguished Ento- 

 mologist. 



4. DiSTYPSIDERA PARVA. 



Brassy-green on the head and thorax, darker and bluish on the 

 elytra, and cyaneous beneath with yellow legs. The head is large, 

 finely acuducted, and less depressed between the eyes than in the 

 other species ; the eyes are very lar'ge and prominent ; the labrum 

 is sti'ongly toothed and white except an unusually narrow stripe 

 on each side ; the palpi are entirely whitish-yellow. The thorax 

 is much naiTOwer than the head, longer than broad, and trans- 

 versely divided as in the other species, but the central section less 

 rounded and nearly parallel-sided. Elytra broader than the thorax 

 and twice the length, transversely rugose and rather densely 

 punctate, rounded at the apex and slightly broader than at the 

 shoulders, the basal third of a dull reddish-yellow, and about the
