Head with a small depression near the base of each antenna ; the punctures 

 barely discernible and scattered. Antennae reaching beyond base of prothorax, 

 second joint the smallest, ninth to eleventh forming a loose club, the eleventh 

 ovate-acuminate, with the inside lightly emarginated. Prothorax not much 

 longer than wide, sides roundly dilated near the middle, before apex with a 

 curved, moderately deep, transverse impression, and with a straight one at the 

 base. Very finely and sparsely punctured, the punctures somewhat more dis- 

 tinct near the apex than elsewhere, the sides at the middle with a fev/, more or 

 less distinct, transverse wrinkles. Elytra wider than prothorax and not quite 

 three times as long, sides subparallel to beyond the middle, then gently rounded 

 off towards apex. The punctures small, but distinct, arranged in double rows, 

 less distinct in the posterior half than in the forepart, the alternate interstices 

 slightly raised. Under-surface lightly punctured ; on the abdomen the punctures 

 are placed, more or less, in transverse rows. Posterior legs longer and more 

 slender than the anterior and intermediate ones. Length, 85 mm. 



Hab. — Queensland: Brisbane (H. Pottinger). Type (unique), in author's 

 collection. 



The dark portion of the head is represented by a round, fuscous spot on 

 the top, midway between the eyes, and is joined to the dark apex of the pro- 

 thorax, the latter having also three dark spots near its lateral margins. The 

 submedian fasciae on the elytra are narrowly infuscated at the suture. The 

 peculiar sculpture of the elytra should make this species easily recognizable ; it 

 is closely covered with large, somewhat shallow, reticulate punctures, with the 

 interstices longitudinally slightly carinate ; and in each of these depressions are 

 placed two smaller ones, side by side, which give the elytra the appearance of 

 having double rows of small punctures, with the alternate interstices carinate. 

 This species differs from the description of 0. cylindricus, Gorh., by not having 

 the head thickly and coarsely punctured, the prothorax only lightly punctured, 

 not at all granulose, and without a pale subapical macula. 



Orthrius tricolor, Schenk. 



A specimen from Sydney, New South Wales, differs from the author's 

 description by having the labrum, and all the tibiae at the apex, testaceous ; 

 and with a small, irregularly-shaped, black macula on the top of the head, 

 midway between the eyes. 



TlIANASIMOMORPHA. 



Mr. Edward A. Chapin, of the Bureau of Animal Industry, V\"ashington, 

 has pointed out to me that the insect determined by Blackburn as Thanasinio- 

 niorpha bipartita, Blanch., is not the species Blanchard described from Guam ; 

 with this opinion I quite concur. 



Gorham remarked (Cist. Ent., ii., p. 62) that Tillus hipartitus, Blanch, 

 (which was subsequently pointed out by Lesne as being a synonym of T. 

 notatus, Klug), did not belong to the Tillides, and that it resembled a Tliana- 

 simus. Blackburn observed this and (Trans. Roy. Soc. S. Austr., 1891, p. 303) 

 proposed the new genus Thanasiniouiorpha, with hipartita, as the type of it. 

 This insect is conspecific with his iiitricata (pi. xv., fig. 3), which he added to 

 the above genus in the same paper that he proposed the new generic name. As 

 the genus Thanasiinomorpha was, apparently, founded as much upon iiitricata 

 as the insect determined as hipartita, Blanch., I consider, in the absence of any 

 definite ruling on this particular point by the International Code, that Black- 

 burn's name for the genus should stand, with intricata, Blackb., as its type, 

 and hipartita, Blackb. (nee Blanch.), as a variety of the above.
