HYDROPHILUS, » Geoffr. 

 H. qnadristriatus, n. sp. — t^longate oval, more attenuate in front, black with 

 slight olivaceous tinge ; surface densely, finely and equally punctured. Head 

 vith sigmoid of row coarser punctures on each side, meeting at the vertex. An- 

 tennte and palpi testaceous. Thorax with a small fovea on each side near the 

 anterior margin within the jiosition of the eyes, and an angulate row of punc- 

 tures on each side near the middle and a few coarse punctures irregularly dis- 

 pose<l. Elytra with four strife of moderate punctures, two strise sutural, ex- 

 tending nearly from base to apex, enclosing at base a short scutellar row; 

 two strife subhumcral obliterated at base and extending nearly to apex, becom- 

 ing confused and extending toward the inner rows. Body beneath black, 

 opaque and pubescent, abdomen with a row of brownish patches at the sides. 

 Legs pale testaceous, femora at base and tarsi black. Length .38 inch ; 9.5 lum. 



Resembles lateralis ia form but is more narrowed before than be- 

 hind. The elytra are evenly punctured and the body along the me- 

 dian line moderately convex. It differs from all our species by the 

 four stria) of punctures on each elytron. The outer two rows corres- 

 pond with an eiuhth and ninth while traces of a third, fourth and fifth 

 are evident at base. 



Collected by Prof. Verrill, near the sea coast of New Jersey. 



PHYTOSUS, Curtis. 

 P. littoralis, n. sp. — Head brownish testaceous, moderately shining, sparse- 

 ly clothed with yellowish hairs, front feebly concave; parts of mouth and an- 

 tennae testaceous, the latter darker at tips. Thorax paler than the head, as 

 broad as long, disc depressed, sides strongly rounded in front, behind the mid- 

 dle sinuate, base truncate feebly emarginate at middle, and slightly broader 

 than half the width of thorax at middle; surface sparsely punctured and pub- 

 escent. Elytra pale testaceous, sparsely punctured and pubescent, short, sides 

 strongly divergent behind, body apterous. Abdomen elongate oval broader be- 

 hind the middle, shining and very sparsely pubescent. Legs pale testaceous. 

 Last segment of abdomen % slightly prolonged at middle, and sinuate on each 

 side. Length .08 inch; 2 mm. 



The male resembles in its sexual characters /'. haltum, Kraatz, but 

 the median prolongation of the last abdominal segment is broader. 

 The penultimate segment is subearinate along the median line poster- 

 iorly. The mandibles are more prominent than in our California spe- 

 cies. 



One specimen collected by Prof. A. S. Verrill, on the sea coast of 

 New Jersey. 



* Note. — This and the next species were obtained from a small collection 

 made on the Jersey coast and descriptions and a list of the other species pre- 

 pared for Prof. Verrill. Owing to the delay in publication and desirability of 

 keepiug descriptions of new species close together and not widely scattered in 

 many journals, permission has been obtained to present them in these Transac- 

 tions.
