70 U. S. p. R. R. EXl*. AND SURVEYS ZOOLOGY 47TH PARALLEL. 



A very fine species found by Mr. Gibbs at Steilacoora. Belongs to the group named Adi- 

 monia ; I am not prepared to adopt it as a genus, as I have failed to discover sufficient reason 

 for its separation. 



G. consjmta, elongata, luteo-testacea^ pubescens, confertim minus subtiliter punctata, capita 

 Unea media nigra, thorace canaliculato et untrinque ad latera vage impresso, vitta dorsali 

 nebulaque laterali nigris ; elytris intra humeros oblique, et versus latera a humeros postice late 

 impressis, sutura elevata guttisque plurimis parvis nigris; subtus fusca, pedibus testaceis nigro- 

 punctatis. Long. "15. 



San Jose, California. The lateral impression of the elytra extends from the humerus for two- 

 thirds their length, running a little inwards from the margin, and becoming obsolete ; the black 

 spots along its inner margin are frequently confluent into a vitta. 



G. guttulata, elongata, fusco-testacea, valde cinereo-pubescens, dense fortius punctata, thorace 

 brevi late canaliculato, ad latera inaequali ; elytris intra humeros oblique impressis, ad mar- 

 ginem late sulcatis, guttis rotundatis nigris parce subseriatim notatis. Long. '19. 



One specimen, San Francisco. Larger than the preceding, with the suture not elevated, and 

 not black. 



G. morosa, elongata, piceo-nigra, tenuiter cinereo-pubescens, capite subtiliter dense punctato, 

 callis duobus supra antennas laevibus, thorace valde punctato, inaequali, medio profunde, versus 

 latera vagius foveato ; elytris thorace parum latioribus convexis, confertim minus subtiliter 

 punctatis, sutura elevata, versus scutellum jilaua. Long. "25. 



One specimen, San Francisco. 



PSTLLOBORA Muls. 



P. laedata, rotundata, supra pallida, thorace maculis (juatuor obscuris, elytris subtiliter 

 parcius i)unctulatis, maculis magnis testaceis nigro-variegatis confluentibus ; subtus testacea, 

 parapleuris pedibusque pallidis. Long. 'lO. 



San Francisco, abundant. Smaller than P. 20-maculaia Muls.; the elytra are less strongly 

 and less densely punctured ; the spots are larger and confluent, of a paler color, with only some 

 portions black ; thejiarapleurae are also entirely white. 



Chilocorus Leach. 



C. fralcrmis, niger, nitidus, thorace lateribus rotundatis, elytris macula rotundata rubra 

 utrinque ornatis, disco vix conspicue, versus marginem distinctius punctatis abdomine rufo, 

 segmento primo medio nigro ; epipleuris oblique declivibus parum concavis. Long. -2. 



One specimen, Sacramento, Mr. Wittick. Eesembles in every respect C. hivulnerxis Muls., 

 except that the punctures of the elytra are less distinct and almost obsolete, and by the epipleurae 

 being less concave anteriorly. 



HiPi'ODAMiA Muls. 



H. moesta, rufescente-nigra nitida, dense subtiliter punctulata, macula rhomhoidea frontali, 

 thoracis margine laterali antice posticeque latiore, linea dorsali antica, guttisque dorsalibus. 

 duabus albis ; elytris thorace latioribus, macula laterali alba triangulari ad dodrantem ornatis 

 Long. -3.
