Genera and Species of Coleoptera. 121 



Docalis [Tenebrionidae]. 

 Head rounded, exserted, the antennary orbit nearly dividing the eye. 

 Antennae short, covered with numerous small flattish hairs, the first 

 three joints longest, the rest transverse, the tenth larger than the 

 eleventh. Mandibles stout, bifid at the apex. Palpi robust, terminal joint 

 of the maxillary short, stout, of the labial obconic, obtuse ; external 

 maxillary lobe short, triangular, fringed, the inner narrow, toothed. 

 Mentum arising within the jugular plate. Pro thorax subquadrate, 

 scarcely wider than the head. Elytra ovate-oblong, broader than the 

 prothorax. Legs short, the intermediate furnished with trochanters ; 

 coxae not contiguous ; tibiae not spurred; tarsi with all the joints ex- 

 cept the last very short and fringed with spiny hairs. Prosternal pro- 

 cess quadrate. Mesosternum depressed. 



The Tagenia funerosa of the Eev. F. W. Hope is, I think, refer- 

 able to this genus ; and, trusting solely to recollection of his type, 

 now in the Taylor Institute at Oxford, it is very close to, if not 

 identical with, my D. degener ; but without certainty on this point, 

 it is better to assume that they are distinct. The genus seems to 

 be referable to the Scaurinse, and, so far as my knowledge of the 

 group extends at present, it might follow Ammojphorus. The struc- 

 ture of the mouth, in reference to what I have called the " jugular 

 plate," but which appears to be the " sow-menton " of M. Lacordaire, 

 is very similar, judging from that author's description, to that of 

 Nyctoporis, which genus immediately precedes Ammophorus. The 

 larger penultimate joint of the antennae is suggestive in a slight 

 degree of the club of many Colydian genera ; indeed, there are so 

 many points of resemblance between several of the Heteromera and 

 the Colydiidae, as to justify a doubt whether they may not be more 

 than mere analogies. 



Docalis exoletus. (PI. VIII. fig. 9.) 



D. oblongo-ovatus, fuscus ; prothorace transverso. 



Hah. Australia (Melbourne) ; Tasmania. 



Oblong-ovate, dark brown, everywhere covered, but not very closely, 

 with semi-erect, stiff black scales (hairs), intermixed, especially on 

 the head and prothorax, with rusty-white ; prothorax slightly broader 

 than long ; scutellum rounded behind j elytra coarsely seriato-punctate, 

 marked with several slightly elevated longitudinal lines, which are 

 severally crested with a row of whitish scales ; body beneath punctured, 

 each puncture enclosing a short rusty hair. Length 2 to 3 lines. 



For my knowledge of this and the species of the two preceding 

 genera, I am indebted to Robert Bakewell, Esq., who informs me 

 that they, and many other insects as well, are found beneath the
