ECTINOCEPHALUS.—CONODES. 107 
rounded and rather strongly margined, broadly inflexed beneath ; apex rounded. Abdomen with the 
pygidium exposed. Legs robust, bright yellow. Underparts rufo-testaceous. 
Hab. Guaremaa, Capetillo (Champion). ‘Two examples. 
The prominent and wholly exserted head, which, from its peculiar form, cannot be 
withdrawn, but is fitted by an elevated ridge to the anterior margin of the thorax, is 
alone sufficient to distinguish this species from all which have hitherto been discovered. 
CONODES *, gen. nov. 
Corpus conicum, depressum, pubescens. Caput sessile, deflexum; oculis magnis. Pronotwm antice excisum, 
angulis posterioribus haud productis. Hlytra longa, postice attenuata, apicibus rotundatis. Antenne haud 
geniculate, articulis decem composite, sexto quam septimo majore, clava valde incrassata. Prosternum 
permagnum, inter coxas elevatum, et postice dilatatum ; episternis parvis, angustis; epimeris magnis, 
receptacula coxarum late complexis. Mesosternwn longum ; episternis longis, angustis ; epimeris sat parvis, 
ad coxas non extensis. Metasternum modicum, ad latera corporis non extensum ; episternis longis. 
Venter segmentis quinque compositus, primo permagno, apicali precedente duplo longiore. Pedes modici, 
simplices; tarsis brevibus, robustis; unguitus longis, gracillimis, antice convergentibus. 
Body conical, depressed, pubescent. Head not concealed by the thorax, sessile, deflexed ; eyes large, not 
prominent; gular region convex; mouth prominent; antenne inserted some distance in front of the eyes. 
Thorax excised in front, the posterior angles not produced. Scutellwm large and broad, slightly rounded. 
Elytra long, attenuated posteriorly, separately rounded at the apex, broadly inflexed beneath. Abdomen 
with the pygidium exposed, Antenne not geniculated, 10-jointed—1 long, robust, slightly recurved, 
2 smaller than 1, incrassate, 3, 4,5 very small, 6 larger than 7, 8-10 much incrassate, forming a rather close 
gradually incrassated club, the apical joint larger than the preceding, rounded. (Parts of the mouth not 
dissected.) Prosternum very large, elevated between the cox, produced and dilated posteriorly ; epesterna 
small and narrow; epimera large, broadly enclosing the coxal cavities, the cavities oval, oblique. Meso- 
sternum rather large ; episterna very long and narrow; epimera rather small, not extending to the cavities. 
Metasternum moderate, not extending to the sides of the bedy; episterna very long ; epimera concealed 
by the elytra ; hinder margin of the metasternum straight. Venter composed of five segments—l1 very 
long, longer than the metasternum, broadly depressed at the sides to receive the femora, 2~4 nearly equal 
in length, 5 nearly twice as long as 4, obtuse and simple. Legs: anterior with the trochanters small, 
triangular; femora robust; tibie simple, much dilated towards the apex; tarsi short, robust, 4-jointed— 
1 rather longer than 2, 2 and 3 equal, 4 rather short; claws very long and slender, converging ante- 
riorly ; intermediate similar to the anterior, the tarsi rather longer ; posterior similar to the preceding, the 
trochanters with the interior angle much produced and acute. Cove: anterior moderately separated, 
not prominent; intermediate rather distant; posterior widely separated, pyriform, rather short, not 
extending to the sides of the body. 
This interesting genus is distinguished from the rest of its family by its depressed 
conical form, deflexed and sessile head, and by the excavation of the front of the thorax. 
Like Ectinocephalus it bears an outward resemblance to the Cryptophagide, but its 
anatomy is strictly Corylophide; on account of their rarity I have not ventured to 
dissect the organs of the mouth in this genus, or in Ectinocephalus, or Microum, and 
have therefore refrained from attempting to describe them, although the more prominent 
parts are sufficiently visible under a high power to satisfy any one that they are of the 
usual Corylophide type, especially in the shape of the maxillary palpi. 
The single species from Guatemala now described is the only one known to me.
