1919] Californian Species of Mathodes 35 



punctate, disk biimpressed at middle, sometimes only feebly so. Length 

 about 2^/2 mm. 



Abdominal sexual characters. Seventh ventral of male simple and 

 not produced; genital appendages short, consisting of two piceous 

 slender lateral processes, hooked (abruptly bent at right angles and 

 acuminate) at tip; a central piece, pale in color, broad at base, with a 

 very thin laminate keel beneath and a curved terminal filamentous 

 process. 



California. Described from Santa Cruz Island. Specimens 

 in my collection are from Riverside, Pomona, Pasadena, Mt. 

 Wilson and San Bernardino Mts., May, July. 



The abdominal characters of the male as given by Le Conte 

 in his synopsis of the Lampyridas (Trans. Am. Ent. Soc, 1881, 

 p. 60), do not seem to apply to the species here described, but 

 the fact remains that there are no males in the Le Conte col- 

 lection. Two females only represent the species, the first 

 (on the label) being the original Santa Cruz Island type, while 

 the second— a later acquisition — is evidently a different species. 

 Specimens of the species I have described above were carefully 

 compared with the Santa Cruz type and are to all appearances 

 identical. 



Malthodes magister sp. nov. 



Piceo-testaceous, head darker, thorax f ulvotestaceous with a blackish 

 discal spot in the type which is nearly obsolete in a second example. 

 Antennae entirely fuscous, passing the elytral tips in the male; joints 

 2-4 distinctly increasing in length, the intermediate joints fully four 

 times as long as wide. Head (cf") distinctly wider than the thorax, eyes 

 only moderate in size, separated in front by more than twice their own 

 width as seen from the front. Thorax but slightly wider than long, the 

 front angles a little prominent and reflexed, sides behind the angles 

 narrowly margined, surface finely sparsely punctulate. Length 4.5 to 

 5 mm. 



Abdominal sexual characters. Male: Sixth ventral deeply, broadly 

 emarginate; seventh moderately produced, tip gradually narrowed and 

 rounded, entire. Within the seventh ventral is a broad tongue-like 

 process which is emarginate at tip. The terminal dorsal segments 

 project considerably beyond the ventral at apex. Female not known. 



California. Humboldt Co. The type collected at Blair's 

 Ranch, Redwood Cr., Sept. 6, by H. S. Barber; the second 

 example at Green Point, June 4, by Dr. F. E. Blaisdell. This is 

 the largest species yet discovered in our fauna and is quite 

 distinct in the male sexual characters.
