those of the type are laterally compressed. Quelle’s profwsa [not examined] is 
probably obtectus Say. 
BIOLOGY AND HABITS. The larvae of D. fasciata (Linnaeus) has been described 
by Perris (1876: 169). The larvae are predaceous and live in wood, probably 
in the galleries of wood-boring insects (Kirk, 1933). 
SPECIES INCLUDED IN THE GENUS 
Four species are at present assigned to the genus. Three of these were included 
in Delox by Quelle. The fourth, obtectus Say, is probably the species which was 
known to Quelle as profusa. 
Danosoma brevicornis (LeConte) comb. n. 
Adeloceva brevicornis LeConte, 1853 : 491. 
Adelocera profusa Candeze, 1857 : 54. [Synonymized by Arnett, 1952 : 115.] 
Adelocera vetusta Walker, 1866 : 324. [Synonymized with profusa by Candeze, 1891Ic : 13.] 
Adelocera (Delox) brevicornis (LeConte); Quelle, 1932 : 208. 
Lepidotus (Danosoma) brevicorms (LeConte) Arnett, 1952 : I15. 
Lacon (Lacon) brevicornis (LeConte); Arnett, 1953 : 7. 
Adelocera brevicornis LeConte. LECTOTYPE (present designation). U.S.A.: 
9, light blue-grey paper disk [=Lake Superior, see p. 277]; Type 2377 [MCZ 
curatorial label]; Ad. brevicornis LeC. Lac. Sup. [LeConte] (MCZ, Harvard). 
Paratypes: I g, 2 9, all with light blue-grey paper disks and labelled “brevicornis 
4, 3 and 2 respectively (MCZ, Harvard). 
Adelocera profusa Candéze. Holotype. U.S.A.: g, Laf. Oregon; Janson coll. 
1903.130; Oregon. Coll. Reiche; A. profusus Cdz., type [Cand.]; Holotype 
Adelocera profusa Cand. M. C. Lane 1964 [M. C. Lane]; Adelocera profusa Cdze, 
Cand. type (ex coll. de Laferté) [Janson] (BMNH). 
Adelocera vetusta Walker. LECTOTYPE (present designation). CANADA: dg, 
Brit. Colum./64.18 [BMNH registration number = presented by J. K. Lord]; 
vetusta [Walker]; Adelocera vetusta Walker, Brit. Columbia (J. K. Lord) [Gahan]; 
holotype Adelocera vetusta Walk., M. C. Lane 1964 [Lane] (BMNH). 
Candéze (1891c : 13) lists Adelocera cavicollis LeConte, 1859 : 86 as a synonym. 
The description is based on a single specimen found on the shores of Tlamath Lake 
[? Upper Kalmath Lake, Oregon, Arnett, 1952: 115] by Dr Newberry. Arnett 
(1952 : 115) states that this specimen is not in the LeConte collection. I have 
been unable to trace Dr Newberry’s collection. 
Arnett (1952: 115) believes that operculatus Say, 1836, nomen nudum, may 
belong to this species. 
Danosoma conspersa (Gyllenhal) comb. rev. 
Elater conspersa Gyllenhal, 1808 : 377. 
Danosoma conspervsa (Gyllenhal) Thomson, 1859 : 103.
