and the elytra are very minutely punctured ; the two 

 specimens before me seem to belong to the female sex 

 only. 



Gyriodera mblsevicollis, sp. n. 



Below and the head black, thorax strongly transverse, nearly 

 impunctate, fulvous, elytra strongly and closely punctured, fulvous, 

 a spot on the shoulders, and two others placed transversely below 

 the middle, black ; tibiae and tarsi flavous. 



Mas. Mandibles robust, the anterior legs eloDgate as well as the 

 first joint of their tarsi. 



Fern. Smaller, thorax less strongly transverse, the anterior legs 

 less elongate. 



Length J 7, ? 6 millim. 



Short and robust, the head finely and closely punctured at the 

 vertex, transversely grooved between the eyes, the space between the 

 latter closely rugose, the clypeus shining, sparingly punctured, its 

 anterior margin concave, mandibles robust, antennae nearly extending 

 to the base of the thorax, black, the lower three joints fulvous, the 

 fourth and the following joints strongly transverse ; thorax more 

 than twice as broad as long, the sides obliquely narrowed anteriorly, 

 strongly rounded near the base and widened at the same place, the 

 basal margin nearly straight, the median lobe scarcely produced, and 

 narrowly black, the disc swollen at the middle, obsoletely grooved 

 at each side near the anterior and posterior margin, the sides with 

 some very fine punctures, the anterior margin with a more strongly 

 punctured slight depression at the middle, the rest of the surface 

 impunctate ; scutellum elongate, raised and pointed, black ; elytra 

 not more than twice as broad as long, slightly narrowed posteriorly, 

 strongly and closely punctured in irregular rows, the interstices 

 finely wrinkled and very minutely punctured, fulvous, a round spot 

 on the shoulders, a very small spot near the scutellum (absent in 

 the female) and two others directly below the middle, black, below 

 and the femora black, the tibiae and tarsi fulvous, the latter robust, 

 the anterior first joint as long as the following joints together.

Gyriodera seems to me to be the only genus for the 

 reception of this species on account of the swollen disc of 

 the thorax, the comparatively short elytra, and the non- 

 mucronate tibiae ; the sculpturing of the thorax differs 

 from that of the other species of this genus in not being 

 rugose; for the convenience of determination Gyriodera 

 is, I think, rightly separated from Titubcea by Lacordaire,
