Tlic structure of the clypcus is very distinct from any 

 other species. In some points tliis approaches l£. blanda, 

 Ei'ichs. 



Ephutomorpha latideniata, sp. n. 



2 . Nigra ; mandibulis, clypeo, antonnis, verticc, thorace supra, 

 eej»mento dorsali sccundo macula lua^iia laterali utrinque, tro- 

 chanteribus, tibiis basi, tarsisque furniu;ineis ; segraeiito dorsali 

 primo apico late testaceo, argeuteo-jiiloso ; seciiiido apice macula 

 magna bilobata, tertio, quarto (piintoque fascia transversa 

 argeuteo-pilosis ; capite late rectangulari, fronte inter antennas 

 porrecta, lamellata, apice bidentata, thorace angulis posticis 

 bidenticulato. 

 Long. 7-9 mm. 



? . Head very large, rectangular, fully half as broad agiin 

 as long, much broader than tiie thorax, closely punctured, 

 the punctures more or less confluent longitudinally, the 

 front produced between the anteume into a broad lamella, 

 l)ilobed or broadly bidentate at the apex, an oblique carina 

 running from the eye to the base of the anteunaj. Man- 

 dibles with a small but distinct tooth on the inner margin 

 near the apex; second joint of the flagellum twice as long 

 as the third. Thorax coarsely puncturefl, median segment 

 coarsely reticulate, pleurfe smooth ; the thorax and median 

 segment combined n-early twice as long as tiieir greatest 

 breadtii, rounded anteriorly, the prothoracic tubercles 

 marked by a minute tooth, narrowed posteriorly and 

 obliquely truncate, a small tooth at each angle above the 

 truncation. Abdomen sessile, the first segment with a 

 tooth on each side at the base beneath ; second dorsal 

 segment very closely and finely punctured. Pygidial area 

 distinct, smooth and shining. Intermediate and hind tibiie 

 with three or four delicate spines on the outer side.

This species seems to be the western representative of 

 E. sanguiniceps, Andre, from which it differs in the presence 

 of a tooth on the inner margin of the mandibles, the coarser 

 sculpture of the head, the much more strongly produced 

 frontal lamella, and the broader second abdominal segment. 

 The colour is also ditl'erent, but E. sanguiniceps differs mueli 

 in colour in diflcrent hjcalities. In the present species the 

 head is often black, without any red on the vertex. The 

 frontal lamella is somewhat similar to that of scutifrons, 

 Andre, but in that species the head is small and much 

 narrower than the thorax.
