410 MR. MAKTIX JACOB Y ON NEW SPECIES [Nov. 28, 



and very strongly thickened at the anterior angles, the latter 

 produced but not dentiform, the surface impunctate, nearly 

 white ; scutellum dark brown ; elytra of the same colour or dark 

 fuscous, shining, impunctate, each with two white markings, the 

 first at the middle in shape of a transverse band not quite extend- 

 ing to either margin, the second of rounded shape, near the apex ; 

 the breast piceous ; the legs dark fulvous ; the abdomen testaceous 

 or flavous ; claw-joint rather strongly swollen ; prosternum very 

 nai'rovv and parallel. 



JIab. Colombia. 



In some specimens the ground-colour of the elytra is much 

 paler. The absence of a thoracic flattening of the sides and 

 the position and colour of the elytral maikings distinguish this 

 species. 



ASPH^RA BIPLAGIATA, Sp. n. 



Black, thorax and the femora fiavous ; elytra nearly impunctate, 

 the lateral raargins, a large discoidal patch, and the apex flavous ; 

 apex of the posterior femora black. 



Length 5-6 millim. 



Head black, with one or two punctures near the eyes ; antennfe 

 black, the lower two joints flavous below, third and following- 

 joints nearly equal ; thorax nearly twice as broad as long, the 

 sides rounded anteriorly, wath a broad flattened sulcus, the anterior 

 angles thickened but not produced, the surface impimctate, flavous ; 

 scutellum black ; elytra impunctate ; under side, the apex of the 

 posterior femora, and the tibiee and tarsi black, rest of the femoi-a 

 flavous.

This Asjjhcera resembles almost exactly A. episcojxdis 111. in the 

 elytral pattern, which consists of a transverse black band at the 

 base and another near the apex connected by a very narrow 

 sutural stripe, the disc in shape of a large oval patch and the apex 

 as well as the lateral margins being flavous. The diflerences 

 which separate this species are : the entirely black head, without the 

 whitish fi/ontal tubercles ; the anterior angles of the thorax, wdiich 

 are not produced ; the position of the posterior elytral band, which 

 is placed much lower down than in the above-named species ; and 

 the colour of the legs. I have i^eceived several specimens from the 

 La Plata Museum without a special locality. 



ASPH^RA ERICHSONI, Sp. U. 



Black; thorax testaceous, the sides straight, the surface 

 impunctate ; elytra nearly black, the lateral margins and an 

 exti'emely narrow transverse straight band at the middle flavous. 



Length 6 millim. 



Head with a few j)nnctures above the eyes, black, the frontal 

 elevations very broad and flat, scai^cely raised, the base of the 

 antennae flavous; the antennae very long and slender, black, 

 the fourth joint longer than the third ; thorax only about one-
