174 MALACODERMATA. 
Head wider than the thorax across the tubercular swellings, with some shining hairs 
in front, of a ferruginous colour, finely rugulose. Thorax darker than the head, 
granulate punctate, rough, the sides suddenly swollen in front of the middle, the basal 
and front margins and sometimes the whole thorax ferruginous. ‘The elytra are thickly 
and coarsely punctured; at the extreme apex the punctures are obsolete, and the front 
of the white portion there is clothed with silky white hairs; about the middle there is 
a curved white fascia, turning towards the apex at the suture; there is also a badly 
defined oblique line of white hairs from the humerus, meeting at the suture. The 
elytra are usually brown at their base, but are darker between the fascia and the apex, 
and are sometimes dark in the basal half, excepting at the margins. They have often 
a bluish eneous tinge. Seven specimens were collected at Las Mercedes, only one or 
two in each of the other localities. I cannot distinguish the sexes. ‘The specimen 
figured is one from El Tumbador. 
17. Hydnocera intricata. 
Fusca, parum nitida; capite prothoraceque eneo-micantibus, hoc disco intricato ruguloso, antennis et palpis 
fuscis, basi dilutioribus; elytris distincte parcius punctatis, basi apiceque conjunctim cum sutura late 
pallidis, marginibus fuscis, medio albido-fasciato; pedibus basi pallidis, femoribus apice tibiisque 
saturatius brunueis, vel piceis. Long. 6—7 millim. 
Hab. GuatEMALA, Sinanja valley, Vera Paz (Champion). 
Like H. corticina, but more parallel, the elytra not contracted at the middle of the 
margin. The rugulose thorax, which, with the head, is brassy, seems to indicate a 
distinct species. 
18. Hydnocera nigro-znea. 
Hydnocera cerulea (Dugés, coll. Sallé). 
Nigro-cerulea, parum nitida, lata, parcius distincte punctata, nigro-pilosa, pube brevi cinerea depressa parce 
vestita ; corpore infra cum pedibus nigris. Long. 53 millim. 
Hab. Mexico, Guanajuato (Dugés, coll. Sallé), Puebla (Sallé). 
Head and thorax black, very obscurely brassy, very finely and obsoletely punctured, the — 
sculpture almost hidden by the numerous upright hairs and rough depressed pubescence. 
Antenne and palpi dark brown. ‘Thorax as wide as long. FElytra very nearly covering 
the body, wider than the head, very densely covered with small punctures; narrowed 
a little to the apex, and with depressed ashy hairs and upright pile which is black ; 
obscurely brassy black. This is a robust and moderately convex insect, differing from 
the one which follows in many respects, notably in its much finer puncturing of the 
elytra and broader form. ‘There is only one specimen in the Sallé collection (No. 579), 
which is bluish black; others from the same locality, six in number, and one from 
Puebla, agree in being brassy (Nos. 578, 580, 581, 582), and pertain, without doubt, to 
one species. ‘The mouth and anterior tibie are obscurely red in some examples.
