new Species o/Histeridaj. 167 



propygidium is rather densely punctured at the sides, the 

 points becoming finer and less close in the middle, especially 

 behind the base ; the pygidium is evenly and densely punc- 

 tured ; the prosternum is very finely punctulate, and the 

 points are most visible at the base ; the mesosternum emar- 

 ginate, marginal stria complete and well-marked. 



The facies of this species resembles 77. punctistrius, Mars. 

 H. tuber cidipy ejus, Sch., If. fortunatus, 77. Marseuli, Sch., 

 and 77. ebenninus, Er., are the only species I know in this 

 genus in which the mesosternal stria is complete, and the 

 generic name Diospyros has been used for the last two species. 



Hob. Chapada, Matto Grosso (77. H. Smith) . 



Ulster tardigradus, sp. n. 



Ovalis, subconvexus, niger, nitidus ; fronte leviter convexa, stria 

 antice recta, labro seruicirculatiin inciso ; pronoto lateribus nigro- 

 ciliato, stria interna antice, externa pone oeulos, interruptis ; 

 elytris, striis 1-3 integris, 4 basin leviter abbreviata, 5 et suturali 

 brevissimis punctiformis ; pygidio densissime punctato ; tibiis 

 anticis tridentatis. 



L. 12 mill. 



Oval, rather convex, black and shining ; the head, labrum 

 is cut out on the middle of the anterior edge in the form of a 

 semicircle, and the parts adjacent on each side of the incision 

 project a little, the incision occupies rather less than a sixth 

 part of the edge, frontal stria straight anteriorly, not deep but 

 clearly marked, surface feebly convex, not impressed ; the 

 thorax ciliate laterally, outer lateral stria terminating behind 

 the eye, inner stria interrupted behind the neck, within the 

 inner stria on the basal edge is a small oblique impression ; 

 the elytra, stride 1-3 complete, 4 slightly shortened at the 

 base, 5 and sutural very short and consisting of only a few 

 apical punctures, the apical margin of the elytra where the 

 four dorsal stria? end is irregularly strigose ; the propygidium 

 has a small transverse smooth space on either side near the 

 base and opposite to the fourth stria, sides densely punctate 

 and feebly foveolate, median area less closely punctured ; 

 the pygidium is very densely punctate ; the prosternum, 

 anterior lobe obtusely pointed and marginate ; the meso- 

 sternum is smooth, anteriorly emarginate, with the marginal 

 stria interrupted behind the emargination ; the anterior tibise 

 are strongly 3-dentafe. 



The species most similar to the above is 77. robusticeps, 

 Mars. Marseul does not describe the propygidium of his 

 species, but there are two small circular spaces on it which 

 correspond as regards their position with those of If. tardi-
