368 MEMOIRS ON THE COLEOPTERA 



red in cruentata; it also differs in its very much coarser elytral 

 punctures. 



Goes tessellatus Hald., differs from the other species in its larger 

 size, stouter form, in the longer basal joint of the antennae, in the 

 form and vestiture of the scutellum and in having two very faint fine 

 raised lines on each elytron; it occurs exclusively in the southern 

 Atlantic States and a specimen recently received from Mr. Manee, 

 taken at Southern Pines, North Carolina, agrees very well with the 

 type of Hammoderus amplipennis Csy., from the Levette collection, 

 the Colorado label on the latter being erroneous in all probability; 

 the type of amplipennis is shorter and relatively somewhat broader 

 than the Carolina specimen and has a shorter and more transverse 

 prothorax, but they are evidently very closely related. While 

 tessellatus belongs to a special group of Goes, I am not prepared to 

 conclude finally that it belongs truly to Hammoderus, although 

 agreeing almost exactly with typical forms of that genus as depicted 

 in the Biologia. 



The following species is a very distinct member of the typical 

 Goes, as represented by pulverulentus Hald., having a much shorter 

 basal antennal joint than in tessellatus and being devoid of any trace 

 of elevated elytral lines but differing especially in the form of the 

 scutellum, this being smaller, shorter and with strongly parted 

 longer and coarser vestiture, agreeing with pulverulentus and allies 

 in this respect. In tessellatus the scutellum is larger and flatter, 

 with much finer and shorter, dense and even vestiture, which is not 

 definitely parted along the middle. In the Carolina specimen al- 

 luded to, which I hold to be typical tessellatus, the scutellum is 

 rather longer than wide, but in the type of amplipennis it is broader 

 and more parabolic in outline. 



Goes robinsoni n. sp. Form stout, parallel, piceous-black, densely 

 clothed with short coarse ochreous hairs, condensed in spots about half 

 as large as the scutellum, which are scattered sparsely and without order 

 over the elytra, the latter without trace of fasciae, nubilous or otherwise; 

 head slightly narrower than the prothorax, with a fine entire median 

 incised line; antennae slender, a fourth longer than the body, the basal 

 joint twice as thick as the succeeding joints, feebly obconic, two and one- 

 half times as long as wide, very finely punctulate and with close small 

 decumbent hairs, with a few longer erect black bristles above and beneath, 

 two-thirds as long as the third joint; prothorax not quite one-half wider 

 than long, of the usual form, the spine acute, the surface rather coarsely 

 and densely punctato-rugose and with short close-set hairs; scutellum
