obsolete), the humeri prominent (formed by the extended margin); anterior tibie coarsely, the inter- 
mediate ones more finely, denticulate on their outer edge; outer apical angles of all the tibie produced and 
dentiform, the spurs strong; tarsi short, the basal joint of the posterior pair stout and a little longer than 
the two following joints united, the last joint thin and about as long as the first ; prosternum broad, 
subhorizontal, the apex a little produced and rounded; metasternum short; intercoxal process broad, 
rounded in front; epipleurse broad, and extending to the apex of thé elytra. 
The above characters have been drawn up to receive a single species from British 
Honduras. 
From Delognatha, Lac., of which several species have been described from Tropical 
South America, this genus may be known by its much shorter and more convex form, 
the lateral margins of the front not swollen, the almost obsolete scutellum, the more 
prominent humeri, the comparatively much shorter elytra, &c.; allied also, but more 
distantly, to Pycnochilus, Waterh. 
The sexes appear to be externally similar as in Phrenapates. 
1. Daochus mandibularis. (Tab. VII. fig. 2; 2a, labium; 26, maxilla and 
maxillary palpus.) 
Oblong ovate, broad, very convex, reddish brown or black, shining. Head and labrum coarsely and closely 
punctured; prothorax strongly transverse, the anterior angles produced and prominent, but obtuse, 
widest about the middle, narrowing a little at the base, the base truncate (without fovez), the surface 
very coarsely and somewhat closely punctured (rather more sparingly than the head), the space between 
the punctures (seen under a strong lens) exceedingly minutely and closely punctured ; elytra the width of 
the prothorax at the base, very short and convex, slightly rounded at the sides, widest about the middle, very 
coarsely and deeply punctate-striate (the punctures transverse and closely placed), the interstices becoming 
strongly convex outwardly, and almost smooth ; beneath shining, coarsely and rather closely punctured. 
Length 6—7 millim.

Two examples. 
Group ULOMIDES. 
This group will contain a large number of genera, many of which will doubtless 
eventually have to be separated, but for the purposes of this work I have not thought 
it necessary to divide it. As understood here, it will include the genera placed in it 
by Lacordaire, except Anepsius, and those from Hypophleus onwards; and also those 
included in it by Leconte and Horn (Class. Coll. N. A. 1883, p. 381), with the exception 
of Evoplus, which is here referred to the group “ Diaperides,” to which group Hypophleus 
is also now considered to belong. I have also included in it Sitophagus and Doliema 
(=Sitophagus, Horn), which seems to me to be more nearly allied to the “ Ulomides,” 
notwithstanding the differences in the structure of the male antennez and the slightly 
gaping middle coxal cavities (the small trochantin in consequence slightly visible, as is 
also the case in Mophis), than to the “ Tenebrionides,” with which Doliema is associated 
by Dr. Horn: possibly they wiil form the types of a new group. 
For the reception of the numerous Central-American species many new genera have
