- HYDNOCERA.: * 175 
19. Hydnocera cyanipennis. 
Nigra, oblonga, parallela; supra eneo-micans, elytris cyaneis, crebre et fortiter rugose punctatis ; ore, palpis, 
antennarum basi trochanteribusque flavis. Long. 5 millim. 
Hab. Guatemata, Calderas, Capetillo, Quiche Mountains (Champion). 
A very much narrower, more parallel and slightly built species than H. nigro-cnea. 
The underside is shining black, the only yellow parts being the mouth (the labrum 
excepted), palpi, antennz (excepting the upperside of the last joint and one or two 
preceding it), and trochanters; sometimes, however, the anterior tibie are obscurely 
pale. The disk of the thorax is finely and irregularly rugulose; the widest part is a 
little in front of the middle; the upright pile and the pubescence is much less dense | 
than in H. nigro-enea. . The elytra are greenish blue, with coarse, closely packed, and 
occasionally confluent punctures, irregularly disposed but uniformly distributed. There 
is a very indistinct commencement of a fascia of ashy hairs on the middle of the margin. 
The elytra cover the abdomen completely, and are together rounded at their apices. 
Nine specimens from Calderas, one from each of the other localities. 
20. Hydnocera cincta. (Tab. IX. fig. 8.) 
Hydnocera cincta, Spin. Mon. ii. p. 48, t. 39. fig. 5°. . 
Hab. Muxico (Sallé); Guatnmata, Capetillo, Duefias, Zapote, Cerro Zunil, Las 
Mercedes, Rio Maria Linda, Guatemala city; Panama, Boquete, Volcan de Chiriqui 
(Champion).—Soutu America, Cayenne 1, Amazons (Bates, coll. Gorham). 
The specimen figured is one from Cerro Zunil. Varies in the colour of the legs, 
from nearly black with pale bases, to pale with only the knees, hind tibie, and tarsi 
darker. 
Although found in such widely separated localities, I have no doubt that my own 
specimen from South America and the series collected by Champion belong to one 
species; and I think there is hardly any doubt I have identified it correctly with 
Spinola’s species. 
Section B ii. Elytra covering the abdomen; shoulders carinate, lateral margin 
sinuate posteriorly. 
21. Hydnocera cryptocerina. 
Nigra, obscure czrulescens, fortiter subrugose punctata; elytris medio albo-fasciatis, fascia ad suturam intérrupta, 
ad marginem latiore; capite prothoraceque obsoletius punctatis; pedibus basi, genis et antennis (apice 
excepto) testaceis, humeris etiam nonnunquam puncto pallido notatis. Long. 4—5 millim. 
Hab. GUATEMALA, Chacoj, Teleman, El Reposo, El Tumbador (Champion).

In the section to which this species belongs the humeral callus is prolonged as a 
curved carina towards the suture, and the margin is a little reflexed and beyond the
