Longiconiia of Mexico and Central America. 261 



Tcssarecplwra araclinoides, Thorns. 



To the localities previously known for this species 

 may be added Acapulco in Guerrero, from which Herr 

 Hoge has sent one example. This appears to he the 

 most northern limit yet recorded. 



HoM(EOPHL(Eus, gen. nov. 

 Female. Form broad aucl robust. Head flattened in front, 

 widened out at the base, with the cheeks rather long and promi- 

 nent. Eyes emarginate, with the lower lobes somewhat trans- 

 verse. Autennge about one-third longer than the body, ten-jointed, 

 with the tenth joint very short, the first joint stout and clavate, the 

 third longer than the first, and slightly thickened towards the apex. 

 Prothorax transverse, with two tubercles on the disk, and furnished 

 on each side with a median conical tubercle, and, lower down, a 

 smaller anterior tubercle. Elytra much broader across their base 

 than the base of the prothorax ; their length to their united breadth 

 in the ratio of about 3 to 2; sides subparallel ; apices broadly and 

 conjointly rounded. Femora strongly clavate ; tibisE regular, those 

 of the middle pair grooved obliquely on their outer face. Claws 

 of tarsi divaricate. Intercoxal processes of the pro- and meso- 

 sterna very broad and flat. Cotyloid cavities open on the outside. 



This genus appears to be allied to Omjchocerus, Serv., 

 the species of which it closely resembles by its rather 

 short robust form, the inequalities of its elytral surface, 

 and its general bark-like style of coloration ; it has, 

 however, much broader sternal processes than Oni/cho- 

 cerus, and is further to be distinguished by the less 

 number of joints to, and the absence of a claw-like 

 terminal joint from, the female antennae. 



Homceophloeus licheneus, sp. n. (PI. XII., fig. 6). 



Cinereo-pubescens, atro fuscoque plagiatus ; prothoracis disco 

 medio fusco tuberculis duobus nigris nitidis munito ; elytris basi 

 sparsim granulatis, utrisque tuberculo magno basali et costis tribus 

 oblusis, munitis. Long. 21, lat. 10 mm.

Pubescence ashy grey in colour, with blackish and brownish 

 patches. Head sparsely punctured, ashy grey on the sides and 

 lower part of the front, brown above. Prothorax sparsely punc- 

 tured, the punctures almost wholly confined to the sides and mur-
