K62 COLEOPTERA. 



than fourth, truncate behind, sixth of nearly similar length, with a trans- 

 verse median fovea. 



The short thorax and elytra, remarkably dilated femora, tarsal structure, 

 and abbreviated metasternum will enable entomologists to identify it readily.

Wadestown, near Wellington . A single male sent on the 10th August, 

 1916. Another of Mr. A. C. O'Connor's novelties 



•4250. Somatidia o'connori sp. now 



Elongate, narrow, moderately convex, subopaquc ; castaneous. but with 

 the sides of the elytral dorsum from behind the base to near the extremity, 

 and a band across the top of the hind slope nigrescent ; antennae of a paler 

 chestnut hue near the base, but with the apical half of joints 5-10 dark- 

 fuscous, the basal almost testaceous ; femora fuscous, as is the upper portion 

 of the tibiae, the lower part and the tarsi testaceous ; pubescence mostly 

 short, depressed and greyish, flavescent on the back of the head, on the 

 front of thorax, and along the middle near the base, and forming about 

 six small elytral crests, two of these, however, are dark at the base. 



Head with very few fine punctures and a thin median carina in front, 

 rather darker and broadly bisulcate above. Thorax oviform, very slightly 

 longer than broad, evidently more convex and wider at the middle than 

 elsewhere, distinctly but not closely punctate, even less closely just behind 

 the middle. Scutellum yellowish, elongate, triangular. Elytra of same 

 width as thorax at the base, fully double its length, very elongate-oval, 

 before the middle only slightly broader than the thorax ; their punctation 

 is subseriate, as distinct as that of the thorax but a little finer towards the 

 apices : third interstices indistinctly elevated, with an obtuse blackish crest 

 tipped with yellow before the middle, on each, and a small yellow one on top 

 of the hind slope, half-way between these but nearer the outside there is 

 another small yellow one. 



Legs elongate ; femora slender near the base, moderately clavate beyond ; 

 basal joint of anterior tarsi hardly as broad as the second. 



Antennae nearly as long as the body, their elongate third joint does not 

 reach the thoracic base, fourth rather longer than fifth. In 1052 and 3345 

 the third antenna! joint just passes the shoulder. 



Underside dark fuscous ; abdomen elongate, basal segment in the middle 

 double the length of the next, 2-4 become shorter and narrower, their 

 pubescence yellow at the extremity. Coxae fusco-nifous. Mesosternal 

 process cuneiform, tapering towards the back of the middle coxae. Pro- 

 sternal process slightly arched and obtusely carinate along the middle. 



This should be placed near S. uuyusta (1052), which, however, has the 

 thorax more finely and quite closely punctured. S. nodularia (3345) has 

 a pair of smooth nodules on the thorax, and in both of these the back of 

 the head is depressed and usually intensely black. The structural details 

 of the lower surface are also very different.
