142 DESCRIPTIONS OP NEW SPECIES. 



species in my collection, in which the last joint of the antennae in 

 the males is as long as the five preceding, and in the females 

 about as long as the three preceding united. The first interval 

 of the elytra has three punctures behind the middle, the third has 

 six to eight along its whole length, and the fifth has five or six 

 also along its whole length. This species seems quite distinct 

 from any of those of Mexico described by Makliu.* 



HYPORHAGUS THOMSON. 



432. H. opacullis. Ovalis piceus subnitidus, capite thoraceque 

 confertim punctatis, hoc latitudine breviore antrorsum angustato, apice 

 bisinuato, angulis anticis distiuctis, margine apicali lateribusque rufes- 

 centibus, lateribus fere rectis, angulis posticis rectis ; elytris striis punc- 

 tatis, externis duplicatis, extrorsum subcostatis, interstitiis parce obsolete 

 punctiilatis. Long. '21 -23. 



Mas tarsis anticis articulis tribus paulo dilatatis, subtus spongiosis ; gula 

 mox pone mentum fovea impressa, fasciculo parvo acuto pilorum gerente. 



. Two males, collected at Cape San Lucas, Lower California, by 

 Mr. Xantus. This species resembles in sculpture the figure of 

 H. yucatanus Thomson, Ann. Ent. Soc. Fr., I860, pi. 3, f. 8, but 

 the form of body and especially that of the thorax resembles more 

 nearly H. costulatus Thorns., ibid. f. 12; the sexual characters 

 mentioned above also exist in H'. punctulatus. In one of the 

 specimens the color is 'nearly uniform piceous ; the other is 

 darker, with the prosternum, feet, and abdomen reddish piceous.

A very singular insect, of which one specimen was collected 

 in North Carolina, by Prof. Hentz ; recently Mr. Ulke found 

 several specimens near Cresson, Pennsylvania, at the summit of 

 the Alleghanies. It differs remarkably- from the other genera 

 not only by the firmer consistence of the tissues, and the peculiar
